skip About-row brand mark on macOS

NSMenuItem.setImage stretches the row to the leading image's pixel
size regardless of the surrounding rows, so any non-empty bitmap on
the About entry made it visibly taller than the rest of the tray
menu — leaving 16, 18 or 22 px versions all looking wrong next to
the unadorned rows above and below.

Drop the macOS brand mark and gate the SetBitmap call on a non-empty
byte slice; iconMenuNetbird is now nil on macOS, so the About row
falls back to text only. Windows and Linux still ship the brand mark
through their per-platform embed files.

-## Discuss changes with the NetBird team first
-
-Changes to the **public API**, **gRPC protocols**, **functionality behavior**, **CLI / service flags**, or **new features** should be discussed with the NetBird team before you start the work. These surfaces are part of NetBird's contract with operators, self-hosters, and downstream integrators, and changes to them have compatibility, security, and release-planning implications that benefit from an early conversation.
-
-Open an issue or reach out on [Slack](https://docs.netbird.io/slack-url) to talk through what you have in mind. We'll help shape the change, flag any constraints we know about, and confirm the direction so the PR review can focus on implementation rather than design.
-
-Typical bug fixes, internal refactors, documentation updates, and tests do not need pre-discussion — open the PR directly.
-
 ## Directory structure
 
 The NetBird project monorepo is organized to maintain most of its individual dependencies code within their directories, except for a few auxiliary or shared packages.

 **NetBird combines a configuration-free peer-to-peer private network and a centralized access control system in a single platform, making it easy to create secure private networks for your organization or home.**
 
 **Connect.** NetBird creates a WireGuard-based overlay network that automatically connects your machines over an encrypted tunnel, leaving behind the hassle of opening ports, complex firewall rules, VPN gateways, and so forth.
 
 **Secure.** NetBird enables secure remote access by applying granular access policies while allowing you to manage them intuitively from a single place. Works universally on any infrastructure.

 ### A bit on NetBird internals
-- Every machine in the network runs the [NetBird agent](client/), which manages WireGuard.
-- Every agent connects to the [Management Service](management/), which holds network state, manages peer IPs, and distributes updates to agents.
-- Agents use ICE (via [pion/ice](https://github.com/pion/ice)) to discover connection candidates for peer-to-peer connections.
-- Candidates are discovered with the help of [STUN](https://en.wikipedia.org/wiki/STUN) servers.
-- Agents negotiate a connection through the [Signal Service](signal/), exchanging end-to-end encrypted messages with candidates.
-- When NAT traversal fails (e.g. mobile carrier-grade NAT) and a direct p2p connection isn't possible, the system falls back to a [Relay Service](relay/) and a secure WireGuard tunnel is established through it.
+-  Every machine in the network runs [NetBird Agent (or Client)](client/) that manages WireGuard.
+-  Every agent connects to [Management Service](management/) that holds network state, manages peer IPs, and distributes network updates to agents (peers).
+-  NetBird agent uses WebRTC ICE implemented in [pion/ice library](https://github.com/pion/ice) to discover connection candidates when establishing a peer-to-peer connection between machines.
+-  Connection candidates are discovered with the help of [STUN](https://en.wikipedia.org/wiki/STUN) servers.
+-  Agents negotiate a connection through [Signal Service](signal/) passing p2p encrypted messages with candidates.
+-  Sometimes the NAT traversal is unsuccessful due to strict NATs (e.g. mobile carrier-grade NAT) and a p2p connection isn't possible. When this occurs the system falls back to a relay server called [TURN](https://en.wikipedia.org/wiki/Traversal_Using_Relays_around_NAT), and a secure WireGuard tunnel is established via the TURN server. 
+ 
+[Coturn](https://github.com/coturn/coturn) is the one that has been successfully used for STUN and TURN in NetBird setups.

+# NetBird Wails UI — Working Notes
+
+This is the Wails v3 desktop UI for NetBird. Go services live in `services/`; the React/TS frontend lives in `frontend/`; bindings between them are generated under `frontend/bindings/`.
+
+> **Keep these notes current.** When working in this directory with Claude, update this file (and `frontend/CLAUDE.md` for frontend-only changes) whenever you add a service, change an event name, shift a convention, rename a key directory, or land any other change that future-you would want to know about before reading the code. The goal is that a cold-start agent can orient itself from these notes without re-deriving the codebase.
+
+## Layout
+
+### Go (top-level package `main`)
+- `main.go` — app entry. Builds the shared gRPC `Conn`, constructs services, registers them with Wails, creates the main webview window, then starts (in order) the Linux SNI watcher → tray → `peers.Watch` → `app.Run`. CLI flags: `--daemon-addr`, `--log-file` (repeatable; first user-provided value drops the seeded `console` default), `--log-level` (`trace|debug|info|warn|error`, default `info`).
+- `tray.go` — `Tray` struct + menu. Subscribes to `EventStatus`, `EventSystem`, `EventUpdateAvailable`, `EventUpdateProgress`. Owns per-status icon/dot, Profiles submenu, Connect/Disconnect swap, About → Update, session-expired toast.
+- `tray_linux.go` — `init()` sets `WEBKIT_DISABLE_DMABUF_RENDERER=1` to avoid the blank-white window on VMs / minimal WMs.
+- `tray_watcher_linux.go`, `xembed_host_linux.go`, `xembed_tray_linux.{c,h}` — in-process SNI watcher + XEmbed bridge for minimal WMs. See `LINUX-TRAY.md`.
+- `signal_unix.go` / `signal_windows.go` — `listenForShowSignal`. Unix uses SIGUSR1; Windows uses a named event `Global\NetBirdQuickActionsTriggerEvent`. Mirrors the legacy Fyne UI's external-trigger contract so the installer / CLI keep working.
+- `grpc.go` — lazy, mutex-protected gRPC `Conn` shared by every service. `DaemonAddr()`: `unix:///var/run/netbird.sock` on Linux/macOS, `tcp://127.0.0.1:41731` on Windows.
+- `icons.go` — `//go:embed` tray/window PNGs. macOS uses template variants (`*-macos.png`); Linux ships light + dark PNGs; Windows reuses the light PNG (multi-frame `.ico` never redrew on Wails3's `NIM_MODIFY`).
+
+### Wails services (`services/*.go`)
+Each service is registered via `app.RegisterService(application.NewService(svc))`. Every method becomes a TS function in `frontend/bindings/.../services/`. Frontend-facing details (TS signatures, push events, models) are in `frontend/WAILS-API.md`. After editing any `services/*.go` or the proto, regenerate with `wails3 generate bindings -clean=true -ts` (or `pnpm bindings` from `frontend/`). `frontend/bindings/**` is gitignored.
+
+For frontend-side conventions (routing, providers, contexts) see `frontend/CLAUDE.md`.
+
+## Services rundown
+
+All services live in `services/` and assume a build tag `!android && !ios && !freebsd && !js`. Each takes a shared `DaemonConn` (`conn.go`) and is registered in `main.go`.
+
+| Service | File | Responsibility |
+|---|---|---|
+| `Connection` | `connection.go` | `Login` / `WaitSSOLogin` / `Up` / `Down` / `Logout` / `OpenURL`. `Up` is always async (`Async: true`); status flows back through `Peers`. `Login` Down-resets the daemon first to dislodge a stale WaitSSOLogin. `OpenURL` honors `$BROWSER`. |
+| `Settings` | `settings.go` | `GetConfig` / `SetConfig` (partial update — pointer fields are sent, nil fields preserved) / `GetFeatures` (operator-disabled UI surfaces). |
+| `Profiles` | `profile.go` | `Username` / `List` / `GetActive` / `Switch` / `Add` / `Remove`. `List` populates `Email` from the **user-side** state file (`profilemanager.NewProfileManager().GetProfileState`) — the daemon runs as root and can't read it. |
+| `ProfileSwitcher` | `profileswitcher.go` | `SwitchActive` — the single entry point both tray and frontend should use for profile flips. Applies the reconnect policy (see "Profile switching" below), mirrors the daemon switch into the user-side `profilemanager`, drives optimistic feedback via `Peers.BeginProfileSwitch`. |
+| `Peers` | `peers.go` | Daemon status snapshot + two long-running streams (`SubscribeStatus` → `EventStatus`, `SubscribeEvents` → `EventSystem`). Emits synthetic `StatusDaemonUnavailable` when the socket is unreachable. Owns the profile-switch suppression filter (`BeginProfileSwitch` / `CancelProfileSwitch` / `shouldSuppress`). Fan-outs update metadata into dedicated `EventUpdateAvailable` / `EventUpdateProgress` events. |
+| `Networks` | `network.go` | `List` / `Select` / `Deselect` of routed networks. |
+| `Forwarding` | `forwarding.go` | `List` exposed/forwarded services from the daemon's reverse-proxy table. |
+| `Debug` | `debug.go` | `Bundle` (debug bundle creation + optional upload) / `Get|SetLogLevel` / `RevealFile` (cross-platform "show in file manager"). |
+| `Update` | `update.go` | `GetState` / `Trigger` (enforced installer) / `GetInstallerResult` / `Quit`. The install-progress UI lives in its own auxiliary window (`/#/install-progress`), opened by `WindowManager.OpenInstallProgress` — the daemon goes unreachable mid-install so it can't be inside the main window. |
+| `WindowManager` | `windowmanager.go` | `OpenSettings(tab)` / `OpenBrowserLogin(uri)` / `CloseBrowserLogin` / `OpenSessionExpired` / `OpenSessionAboutToExpire(seconds)` / `OpenInstallProgress(version)` / `CloseInstallProgress`. `OpenSettings("")` opens the General tab; pass a tab id (e.g. `"profiles"`) to deep-link, encoded as `?tab=…` in the start URL. `OpenInstallProgress` is `AlwaysOnTop` and hides every other visible window for the duration of the install (restored on close). Auxiliary windows are created on first open and **destroyed** on close (Wails-recommended singleton pattern; prevents the macOS dock-reopen from resurrecting hidden windows). |
+| `I18n` | `i18n.go` | Thin facade over `i18n.Bundle`. `Languages()` returns the shipped locales (`_index.json`); `Bundle(code)` returns the full key→text map for one language so the React layer can drive its own translation library. |
+| `Preferences` | `preferences.go` | Thin facade over `preferences.Store`. `Get()` returns `{language}`; `SetLanguage(code)` validates against `i18n.Bundle.HasLanguage`, persists, and broadcasts `netbird:preferences:changed`. |
+
+`DaemonConn` is defined in `services/conn.go`; `ptrStr` (string-to-*string helper for proto pointer fields) lives there too.
+
+## Daemon proto
+- Proto source: `../proto/daemon.proto`. Generated Go in `../proto/*.pb.go`.
+- Regen: `cd ../proto && protoc --go_out=. --go_opt=paths=source_relative --go-grpc_out=. --go-grpc_opt=paths=source_relative daemon.proto`
+- Pinned versions (see `daemon.pb.go` header): `protoc v7.34.1`, `protoc-gen-go v1.36.6`. CI's `proto-version-check` workflow fails on mismatch.
+- After proto regen, also regen Wails bindings so the TS layer picks up new fields.
+
+## Events bus
+
+`main.go` registers five typed events for the frontend: `netbird:status` (`Status`), `netbird:event` (`SystemEvent`), `netbird:profile:changed` (`ProfileRef`), `netbird:update:available` (`UpdateAvailable`), `netbird:update:progress` (`UpdateProgress`). `netbird:profile:changed` fires from `ProfileSwitcher.SwitchActive` after a successful daemon-side switch — both the React `ProfileContext` and the tray subscribe so a flip driven from one surface paints in the others (the daemon itself does not emit a profile event). Plus three plain-string events:
+
+- `EventTriggerLogin = "trigger-login"` — tray asking the frontend's `startLogin()` to begin an SSO flow.
+- `EventBrowserLoginCancel = "browser-login:cancel"` — the `BrowserLogin` window's Cancel button or red-X close. `startLogin()` listens and tears down the daemon's pending `WaitSSOLogin`.
+- `preferences.EventPreferencesChanged = "netbird:preferences:changed"` — emitted after every successful `SetLanguage` (payload `{language}`). Both the tray menu rebuild and the React `i18next.changeLanguage` subscribe so a flip from any window paints everywhere.
+
+Daemon connection status strings (`services/peers.go`) mirror `internal.Status*` in `client/internal/state.go`: `Connected`, `Connecting`, `Idle`, `NeedsLogin`, `LoginFailed`, `SessionExpired`, plus the synthetic `DaemonUnavailable` emitted by `Peers` when the socket is unreachable.
+
+## Profile switching
+
+`services/profileswitcher.go` is the single source of truth for the reconnect policy. Both the tray (`tray.go switchProfile`) and the frontend's `screens/Profiles.tsx` call `ProfileSwitcher.SwitchActive`; identical inputs give identical state transitions.
+
+Reconnect policy (driven by `prevStatus` from `Peers.Get`):
+
+| Previous status | Action | Optimistic UI | Suppressed events until new flow begins |
+|---|---|---|---|
+| Connected | Switch + Down + Up | Connecting (synthetic) | Connected, Idle |
+| Connecting | Switch + Down + Up | Connecting (unchanged) | Connected, Idle |
+| NeedsLogin / LoginFailed / SessionExpired | Switch + Down | (no change) | — |
+| Idle | Switch only | (no change) | — |
+
+Only Connected/Connecting trigger `Peers.BeginProfileSwitch`. That:
+1. Sets a 30s `switchInProgress` guard.
+2. Emits a synthetic `Status{Status: StatusConnecting}` so both tray and React paint immediately.
+3. Tells `statusStreamLoop` to drop the daemon's stale Connected updates (peer count drops as the engine tears down) and the transient Idle in between Down and the new Up.
+
+`shouldSuppress` releases the guard as soon as a status that signals the new flow began arrives:
+- **Suppressed**: Connected, Idle
+- **Pass through and clear**: Connecting / NeedsLogin / LoginFailed / SessionExpired / DaemonUnavailable
+- **Timeout fallback**: 30s elapsed → clear flag, emit normally.
+
+`Peers.CancelProfileSwitch` aborts the suppression — called by `tray.go handleDisconnect` so the user's "Disconnect while Connecting" click paints through immediately.
+
+Also: `ProfileSwitcher.SwitchActive` mirrors the daemon switch into the user-side `profilemanager` (`~/Library/Application Support/netbird/active_profile`). The CLI's `netbird up` reads this file and sends the resolved profile name back; if it diverges from the daemon's `/var/lib/netbird/active_profile.json`, the daemon silently flips back. Mirror failures don't abort the switch — surfaced as a warning.
+
+## Auxiliary windows (`WindowManager`)
+
+The main window is created up front in `main.go`. Auxiliary windows are created on demand by `services.WindowManager`:
+
+- **Settings** (`/#/settings`) — opened from the header gear icon (`layouts/Header.tsx → WindowManager.OpenSettings("")`), the tray's Settings menu entry (`tray.go openSettings`), and the profile dropdown's "Manage Profiles" entry (`WindowManager.OpenSettings("profiles")`, which sets `?tab=profiles` in the start URL — `Settings.tsx` reads it via `useSearchParams`). The window hosts every settings tab — including **Profiles** (`SettingsProfiles.tsx`, `UserCircle` icon, sits between Security and SSH), which lists profiles in a table with Deregister/Delete in a per-row kebab and an Add Profile button. Both call sites go through `WindowManager` so the user sees the same dedicated frameless window from either trigger — the tray used to repurpose the main window via `SetURL("/#/settings")`, which replaced the main UI in place. Frameless-look (translucent macOS backdrop, hidden inset title bar), fixed 900×640, no resize, no minimise/maximise.
+- **BrowserLogin** (`/#/browser-login?uri=…`) — opened by the connection toggle's SSO flow (`layouts/ConnectionStatusSwitch.tsx`). 460×440, fixed size. The close button (red X) fires `EventBrowserLoginCancel` so the JS-side `startLogin()` can tear down the daemon's pending `WaitSSOLogin`. `WindowManager.CloseBrowserLogin` closes it programmatically when the flow completes.
+- **SessionExpired** (`/#/session-expired`) and **SessionAboutToExpire** (`/#/session-about-to-expire?seconds=<n>`) — opened by `WindowManager.OpenSessionExpired` / `OpenSessionAboutToExpire(seconds)`. 460×380, fixed size, `AlwaysOnTop: true` (the user can't miss them). The React-side buttons close the window via `WindowManager.CloseSession*` and (for Sign-in / Stay-connected) emit `EventTriggerLogin` so the main window's `startLogin()` orchestrator handles the SSO flow. Currently triggered only by the DEV-only "Development" Settings tab; daemon-status integration is a follow-up.
+- **InstallProgress** (`/#/install-progress?version=<v>`) — opened by `WindowManager.OpenInstallProgress(version)` from `ClientVersionContext` (force-install branch on `installing` flip, user-driven enforced branch from `triggerUpdate`). 360-wide auto-sized via `useAutoSizeWindow`, `AlwaysOnTop`. Owns its own polling loop against `Update.GetInstallerResult` with the 5-second daemon-down-grace (sustained gRPC failure = success → call `Update.Quit()`). Hides every other visible window on open (restored on close). The DEV-only "Development" tab has a "Show updating dialog" button that opens this window directly for preview.
+
+All five auxiliary windows are **destroyed** on close (mutex-guarded singleton; `closing` hook nils the field). Destroying rather than hiding is deliberate — Wails' macOS dock-reopen handler resurrects hidden windows, which we don't want for auxiliaries.
+
+The main window is **hidden** on close (the `WindowClosing` hook calls `e.Cancel(); window.Hide()`). The user reaches "really quit" through the tray → Quit menu entry.
+
+## Localisation (i18n)
+
+The locale tree under `frontend/src/i18n/locales/` is the single source of truth for both Go (tray, OS notifications) and React (every user-facing string). Layout: `_index.json` lists shipped languages (`code` / `displayName` / `englishName`); `<code>/common.json` per language. `en/common.json` must exist (the `Bundle` loader hard-fails without it); languages listed in `_index.json` without a bundle are skipped with a warning. Placeholders are single-braced (`"Install version {version}"`) — Go substitutes via `Bundle.Translate(lang, key, "name", value, ...)`; React uses i18next with `interpolation: { prefix: "{", suffix: "}" }`.
+
+Adding a language: drop a `<code>/common.json`, append a row to `_index.json`, add the static import in `frontend/src/i18n/index.ts`, rebuild. Embed lives in `client/ui/main.go`'s `embed.FS`.
+
+Package layout:
+- `client/ui/i18n/` — pure `LanguageCode` / `Language` / `Bundle` loader. No Wails / no daemon. Reads the tree from an `fs.FS` passed in by `main.go`.
+- `client/ui/preferences/` — `Store` persists `UIPreferences{language}` to `os.UserConfigDir()/netbird/ui-preferences.json` (per-OS-user, shared across daemon profiles). Validates against an injected `LanguageValidator` (`*i18n.Bundle`). No file → in-memory default `en`, persisted on first `SetLanguage`. Broadcasts via in-process pub/sub + optional Wails event emitter.
+- `services/i18n.go` + `services/preferences.go` — Wails facades. Preferences emits `netbird:preferences:changed` (payload `{language}`) on every `SetLanguage`.
+
+Key conventions: `tray.*` / `notify.*` (Go-side), `common.* / connect.* / nav.* / profile.* / settings.* / update.* / browserLogin.* / sessionExpired.* / peers.*` (frontend). Keep keys stable — renames cascade everywhere.
+
+## Linux tray support
+
+The in-process `StatusNotifierWatcher` + XEmbed host that lets the tray work on minimal WMs is detailed in `LINUX-TRAY.md` (sibling). Touch that doc when modifying `tray_watcher_linux.go` / `xembed_host_linux.go` / `xembed_tray_linux.{c,h}`.
+
+## Wails Dialogs (frontend, `@wailsio/runtime`)
+
+API surface — `Dialogs.Info` / `Warning` / `Error` / `Question` / `OpenFile` / `SaveFile`, options shape, per-OS behaviour, and the Go-side frameless-window pattern — lives in `WAILS-DIALOGS.md` (sibling). The conventions for **when** to use a native dialog vs inline UI are in the "Conventions" section below.
+
+## Conventions in this codebase
+
+### Errors → native dialogs
+
+User-actionable operation failures (config save, profile switch, debug bundle, update, etc.) surface via `Dialogs.Error` with an action-named title — "Save Settings Failed", "Switch Profile Failed", not "Error" / "Something went wrong". The dialog itself already says "Error" visually.
+
+Confirmations use `Dialogs.Warning` with explicit `Buttons`. The promise resolves with the **button Label string**, not an index — pin the label into a variable before comparing (especially with i18n, where labels translate). Full API in `WAILS-DIALOGS.md`.
+
+**Skip native dialogs** for: inline form validation (`Input.tsx`, URL-format checks — too heavy for keystroke feedback); transient link errors on the dashboard (flap in/out with daemon — use an inline indicator); "partial success" notes inside an otherwise-OK flow (e.g. "bundle saved but upload failed" stays inline). The install-progress window owns its own error UI in-place (timeout/canceled/failed phases) — no native dialog needed there.
+
+### OS notifications
+
+The tray uses Wails' built-in `notifications` service. One `notifications.NotificationService` is created in `main.go` and passed into `TrayServices.Notifier`. Notification IDs are prefixed for coalescing: `netbird-update-<version>`, `netbird-event-<id>`, `netbird-tray-error`, `netbird-session-expired`. Notifications are gated by the user's "Notifications" toggle (cached in `Tray.notificationsEnabled`, seeded from `Settings.GetConfig` at boot). `Severity == "critical"` events bypass the gate, mirroring the legacy Fyne `event.Manager`.
+
+### Profile switching invariants
+
+`ProfileSwitcher.SwitchActive` is the only switch path on the TS side — `ProfileContext.switchProfile` and `screens/Profiles.tsx` both call it. The Go side captures `prevStatus`, drives the optimistic-Connecting paint via `Peers.BeginProfileSwitch`, mirrors into the user-side `profilemanager`, and conditionally fires Down/Up per the reconnect-policy table above.
+
+**Never call `Connection.Up` on an Idle/NeedsLogin daemon** — the daemon's internal 50s `waitForUp` blocks until `DeadlineExceeded`. `Connection.Up` from the frontend is reserved for the explicit Connect button (`ConnectionStatusSwitch.connect`) and the post-SSO resume inside `startLogin`; the gating for profile-switch reconnects lives Go-side in `ProfileSwitcher.SwitchActive`.
+
+## Build / dev tasks
+
+`task dev` (Wails dev, live reload), `task build` (prod build for the current OS, dispatches to `build/{darwin,linux,windows}/Taskfile.yml`), `task build:server` / `run:server` / `build:docker` / `run:docker` (server-mode variants in `build/Taskfile.yml`). **No** `task generate:bindings` alias — run `wails3 generate bindings -clean=true -ts` directly from this directory. CLI flags + log-target semantics are documented in the `main.go` bullet under "Layout".

+# Linux tray support (StatusNotifierWatcher + XEmbed)
+
+Minimal WMs (Fluxbox, OpenBox, i3, dwm, vanilla GNOME without the AppIndicator extension) don't ship a `StatusNotifierWatcher`, so tray icons using libayatana-appindicator / freedesktop StatusNotifier silently fail. `main.go` calls `startStatusNotifierWatcher()` *before* `NewTray` so the Wails systray's `RegisterStatusNotifierItem` call hits the in-process watcher we control.
+
+- `tray_watcher_linux.go` — owns `org.kde.StatusNotifierWatcher` on the session bus if no other process has it. Safe to call unconditionally.
+- `xembed_host_linux.go` + `xembed_tray_linux.{c,h}` — when an XEmbed tray (`_NET_SYSTEM_TRAY_S0`) is available, also start an in-process XEmbed host that bridges the SNI icon into the XEmbed tray. Reads `IconPixmap` over D-Bus, draws via cairo+X11, polls for clicks, fetches `com.canonical.dbusmenu.GetLayout` for the popup menu, fires `com.canonical.dbusmenu.Event` on click.
+
+Build is gated on `linux && !386`; the 386 build (no cgo) and non-Linux builds use the `tray_watcher_other.go` no-op.

+# NetBird desktop UI (Wails3 + React)
+
+Replaces `client/ui` (Fyne). One binary on Windows / macOS / Linux,
+talks to the NetBird daemon over gRPC, renders a React frontend in a
+WebView.
+
+## Prerequisites
+
+- Go ≥ 1.25, Node ≥ 20, **pnpm** (`corepack enable && corepack prepare pnpm@latest --activate`)
+- `wails3` CLI: `go install github.com/wailsapp/wails/v3/cmd/wails3@latest`
+- `task`: `go install github.com/go-task/task/v3/cmd/task@latest`
+- A running NetBird daemon (default: `unix:///var/run/netbird.sock`,
+  Windows `tcp://127.0.0.1:41731`)
+- Linux only: `libwebkit2gtk-4.1-dev`, `libgtk-3-dev`,
+  `libayatana-appindicator3-dev`
+
+## Develop without rebuilding
+
+```bash
+cd client/ui
+task dev
+```
+
+`task dev` runs Vite (port 9245) + the Go binary + a `*.go` watcher.
+Frontend edits hot-reload instantly. Go edits trigger a rebuild and
+relaunch. Pass daemon flags after `--`:
+
+```bash
+task dev -- --daemon-addr=tcp://127.0.0.1:41731
+```
+
+For pure UI work (no native window, fastest loop):
+
+```bash
+cd frontend && pnpm dev
+```
+
+## Production build
+
+```bash
+task build
+```
+
+Output in `bin/`. Frontend assets are embedded into the binary.
+
+### Cross-compile Windows from Linux
+
+Install the mingw-w64 toolchain once:
+
+```bash
+sudo apt install gcc-mingw-w64-x86-64           # Debian/Ubuntu
+sudo dnf install mingw64-gcc                    # Fedora
+sudo pacman -S mingw-w64-gcc                    # Arch
+```
+
+Then:
+
+```bash
+CGO_ENABLED=1 task windows:build
+```
+
+Produces `bin/netbird-ui.exe`. macOS cross-compile from Linux is not
+supported (signing and notarization need a real Mac).
+
+### Windows console build (logs in the terminal)
+
+Default `windows:build` links the binary as a Windows GUI app, which
+detaches from the launching console — `logrus` output, `fmt.Println`,
+and panics go nowhere visible. To debug tray/event/daemon issues:
+
+```bash
+CGO_ENABLED=1 task windows:build:console
+```
+
+Produces `bin/netbird-ui-console.exe`. Run it from `cmd.exe` /
+PowerShell / Windows Terminal and stdout/stderr land in that
+terminal. Same flag works on a native Windows build (drop the
+`CGO_ENABLED=1` if your toolchain already has it set).
+
+## Regenerating bindings
+
+When a Go service signature changes:
+
+```bash
+wails3 generate bindings
+```
+
+`task dev` does this automatically on `*.go` save.
+
+## Tray icons
+
+Source SVGs live in `assets/svg/` (state.svg + state-macos.svg). After editing
+any SVG, rasterize to the PNGs the Go side embeds:
+
+```bash
+task common:generate:tray:icons
+```
+
+Requires Inkscape. Commit the resulting `assets/*.png` files alongside the
+SVG change so CI doesn't need Inkscape installed.

+# Wails Dialogs (frontend, `@wailsio/runtime`)
+
+The frontend dialog API lives in `@wailsio/runtime` as `Dialogs`. Authoritative signatures are in
+`frontend/node_modules/@wailsio/runtime/types/dialogs.d.ts`.
+
+See `CLAUDE.md` for project conventions on *when* to use these (errors vs. inline validation, confirmation flow, etc.).
+
+## Message dialogs
+
+```ts
+import { Dialogs } from "@wailsio/runtime";
+
+await Dialogs.Info({ Title, Message, Buttons?, Detached? });
+await Dialogs.Warning({ Title, Message, Buttons?, Detached? });
+await Dialogs.Error({ Title, Message, Buttons?, Detached? });
+await Dialogs.Question({ Title, Message, Buttons?, Detached? });
+```
+
+All four return `Promise<string>` resolving to the **Label** of the button the user clicked. With no `Buttons` provided you get a single OK button — the promise just resolves when the user dismisses.
+
+`MessageDialogOptions` fields:
+- `Title?: string` — window title (short).
+- `Message?: string` — the body text.
+- `Buttons?: Button[]` — custom buttons. Each `Button` is `{ Label?, IsCancel?, IsDefault? }`. `IsCancel` is what Esc/⌘. triggers; `IsDefault` is what Enter triggers.
+- `Detached?: boolean` — when `true`, the dialog isn't tied to the parent window (no sheet behavior on macOS).
+
+## File dialogs
+
+`Dialogs.OpenFile(options)` and `Dialogs.SaveFile(options)` — see `dialogs.d.ts` for the full `OpenFileDialogOptions` / `SaveFileDialogOptions` field set (filters, ButtonText, multi-select, hidden files, alias resolution, directory mode, etc).
+
+## Per-OS behavior
+
+| Platform | Behavior |
+|---|---|
+| **macOS** | Sheet-style when attached to a parent window. Up to ~4 custom buttons render naturally. Keyboard: Enter = default, ⌘. or Esc = cancel. Follows system theme. Accessibility is built-in. |
+| **Windows** | Modal `TaskDialog`-style. Standard button labels are nudged toward OS conventions. Keyboard: Enter = default, Esc = cancel. Follows system theme. |
+| **Linux** | GTK dialogs — appearance varies by desktop environment (GNOME/KDE). Follows desktop theme. Standard keyboard nav. |
+
+Behavioural notes that affect us:
+- The promise resolves with the **button label string**, not an index. Compare against the literal `Label` you passed (e.g. `if (result !== "Delete") return;`).
+- `Buttons[]` on Linux/Windows uses the labels you supply, but the OS layout/styling is fixed.
+- `Dialogs.Error` plays the platform error sound and uses the platform error icon. Don't use it for confirmations — use `Dialogs.Warning` or `Dialogs.Question`.
+- Don't fire dialogs in a tight loop or from every keystroke — they interrupt focus and (on macOS) animate in/out. Debounce or guard with a `busy` flag.
+
+## Frameless / custom-window dialogs (Go side)
+
+When the native dialog API isn't enough — rich content, embedded webview, multi-screen flow — open a regular Wails window. This is done on the **Go side** via `app.Window.NewWithOptions(application.WebviewWindowOptions{...})`. Useful options:
+- `Parent` — attach to a parent so OS treats it as a child.
+- `AlwaysOnTop: true` — float above the parent.
+- `Frameless: true` — no titlebar/chrome.
+- `Resizable: false` (also `DisableResize: true` in v3) — fixed-size dialog feel.
+- `Hidden: true` initially, then `dialog.Show()` + `dialog.SetFocus()`.
+
+We **do** use this pattern, but pragmatically: `WindowManager.OpenSettings` and `OpenBrowserLogin` are regular small webview windows (not modal sheets) with no resize, hidden minimise/maximise buttons, and a translucent macOS title bar. They're not classic "OS modal dialogs"; they're just lightweight ancillary windows that look the part. Modal behaviour (`parent.SetEnabled(false)`) is intentionally not used — the user can still click back to the main window.
+
+In-app modals (`NewProfileDialog`, delete-profile confirmation, etc.) are Radix `Dialog` primitives inside the main webview. Reach for a custom OS window only when content must escape the main window (BrowserLogin is the canonical example — its lifecycle is tied to the SSO wait) or when the window needs its own taskbar entry / dock icon.
