const characterAnchorPrompt = `Create the canonical character reference for an original collectible-art series.

CANONICAL CHARACTER — LOCK THIS IDENTITY:
Create one original anthropomorphic silver-gray raccoon named RIFT.
Permanent visual features:
- charcoal-black raccoon eye mask with a clean, recognizable shape
- creamy white muzzle, cheeks and chest
- large expressive amber-gold eyes
- small rounded ears; one tiny notch in the RIGHT ear
- short broad muzzle and a subtle confident half-smile
- oversized head with compact athletic humanoid proportions
- thick striped raccoon tail with exactly five dark rings
- soft sculpted stylized fur clumps, never photographic fur
- friendly, clever, confident personality

WARDROBE FOR THE ANCHOR ONLY:
A simple charcoal utility overshirt with no logos, no writing and no theme-specific accessories. Keep the outfit neutral so future images can replace it completely.

COMPOSITION:
Vertical 3/4 character portrait, full torso and most of the tail visible, neutral elegant studio background, clean readable silhouette, centered, no props obscuring the face or tail.

STYLE:
Neutral high-end stylized 3D character illustration, deliberately non-photorealistic, premium animated-feature quality, rounded shapes, rich material detail, cinematic soft key light plus rim light, subtle depth of field, controlled color, polished collectible character reference. Keep the rendering neutral enough that future task-specific style references can deliberately restyle RIFT without changing his identity.

STRICT:
Exactly one raccoon character. No human face. No tiger features. No dreadlocks. No text, numbers, logo, trademark, watermark, card border, UI, duplicate character, photorealistic wildlife or realistic human anatomy.`

REFERENCE IMAGES — SEPARATE IDENTITY FROM STYLE:
Image 1 is the canonical RIFT CHARACTER reference. Use Image 1 only to preserve identity: silver-gray raccoon species, charcoal eye-mask shape, creamy muzzle/chest, amber-gold eyes, right-ear notch, muzzle proportions, head-to-body proportions, five-ring tail and overall face identity. Do NOT treat Image 1's neutral wardrobe, background, lighting or rendering style as fixed.
Image 2 is the TASK STYLE reference. Use Image 2 only for visual language: rendering technique, shape language, material treatment, color behavior, lighting character, texture/detail level and overall illustration mood. Do NOT copy Image 2's subject, species, pose, clothing, cultural symbols, logos, text or composition literally.
Priority rule: identity comes from Image 1; visual style comes from Image 2; wardrobe/theme/scene come from this prompt. If the references conflict, preserve RIFT's identity first and adopt the style reference second.

SUBJECT:
RIFT, one anthropomorphic raccoon character. The character must remain unmistakably animal-like and deliberately stylized rather than realistic or human-faced.

THEME:
%s

RARITY PRESENTATION:
This collectible has rarity tier %s. The illustration itself should feel premium at every tier, but higher tiers may feel more visually spectacular, elaborate or magical in their staging and environmental energy while remaining coherent with the theme.

CLOTHING — PRIMARY VARIABLE:
%s.
The clothing is the main collectible trait. It must instantly communicate the theme, look custom-tailored to RIFT, use premium materials and retain a clear silhouette. No logos or recognizable real-world brand marks.

ACCESSORIES:
%s.

SCENE:
%s.

POSE:
%s.

CAMERA / STAGING:
%s.

COLOR STORY:
%s.

MOOD / LIGHTING:
%s.

ATMOSPHERE:
%s.

SCENE EMPHASIS:
%s.

COMPOSITION:
Vertical 1024x1536 full-art composition. Exactly one dominant character occupying about 65–75%% of the frame. Three-quarter body view with the face and right-ear notch clearly visible and at least most of the striped tail visible. Put the eyes near the upper third. Use foreground/background layering and dynamic depth, but keep the silhouette immediately readable. Leave natural darker breathing room near the very top and bottom so a programmatic collectible-card overlay can remain legible.

VISUAL LANGUAGE — TASK STYLE HAS AUTHORITY:
Follow Image 2 decisively for the rendering language. Recreate its level of stylization, line/edge treatment, brushwork or surface treatment, material abstraction, shading model, texture density, palette behavior, lighting language and finish. The Task Style may be 3D-cartoon, cel-shaded, graphic comic, painterly, watercolor-like, clay/toy-like, low-poly, retro-game-inspired or another deliberately illustrated collectible-art language. Do NOT force RIFT back into the neutral 3D look of Image 1. Preserve the permanent identity markers from Image 1 while translating them naturally into Image 2's visual language. Keep the result premium, coherent, richly art-directed and clearly non-photorealistic.

FULL-ART ENERGY:
The environment should visually merge with the character through thematic particles, light, fabric motion, mist, sparks, petals, snow, dust or other scene-appropriate elements. Create many small visual discoveries while keeping RIFT instantly readable.
