 * add a viewport-narrow banner; the partial responsive classes stay

 * and may help if the decision ever reverses).
 *
 * Banner triggers at < 1024px (Tailwind `lg` breakpoint — the layout
 * starts visibly cramping below this). It's a single fixed bar at the
 * top of the viewport, doesn't block interaction (z-index high, but
 * pointer-events: none on the rest of the body), and dismisses with a
 * one-click "Dismiss" affordance that persists to localStorage.
 *
 * Operators who explicitly want narrow-viewport access (responsive
 * design work, mobile demo, screen-recording at portrait orientation)
 * can dismiss and the banner stays gone for that browser.
