## Architecture du prompt mascotte

| **FIXE** | Forme tête Claude-logo + encoches + style de rendu | ❌ Ne jamais modifier |
| **VARIABLES** | Cheveux, moustache, lunettes, couleur vêtements, accessoires | ✅ Selon l'agent |

---

## Modèles disponibles

## BLOC FIXE — Forme de tête (immuable)

```
A terracotta orange hard plastic head shaped EXACTLY like the Anthropic Claude AI logo — 
a rigid square block with sharp edges, TWO DEEP SYMMETRICAL RECTANGULAR NOTCHES cut into 
the bottom-left corner and bottom-right corner of the lower edge, very slightly rounded 
top corners only. Warm terracotta orange hard plastic surface with glossy sheen.
```

**Règle critique** : Ne jamais supprimer les mentions des encoches (`TWO DEEP SYMMETRICAL RECTANGULAR NOTCHES`). C'est ce qui donne la forme Claude-logo.

### Prompt complet validé ✅

```
Hard plastic toy figurine, collectible action figure, sharp studio lighting, pure white background.

HEAD SHAPE — most important element:
A terracotta orange hard plastic head shaped EXACTLY like the Anthropic Claude AI logo — a rigid square block with sharp edges, TWO DEEP SYMMETRICAL RECTANGULAR NOTCHES cut into the bottom-left corner and bottom-right corner of the lower edge, very slightly rounded top corners only. Warm terracotta orange hard plastic surface with glossy sheen.

EYES: Large cartoon "googly eyes" — very large white sclera dominating the eye area, very small dark brown irises centered, wide-eyed surprised expression.

GLASSES: Fine metallic double-bridge glasses — two horizontal bars connecting the lenses (double bridge), slightly rectangular oval lenses, thin gold/brown metallic frame.

HAIR: Full glossy brown pompadour hairstyle — swept back and up, voluminous wave, shiny hard plastic texture, dark chocolate brown color, sitting on top of the square head.

MUSTACHE: Small neat light beige/blonde walrus-style mustache just above the lip, subtle smile.

COMPOSITION: tight close-up portrait, head centered and filling 80% of frame, pure white background, no body, no text.

STYLE: Hard plastic toy figurine, slightly glossy surface, crisp edges, clean studio shot. NOT soft Pixar — hard toy aesthetic.

## Différences clés Tête Pixar vs Tête Plastique dur

| Dimension | Pixar soft (Tête 1) | Hard plastic toy (Tête 2) ✅ |
|---|---|---|
| Style | `Pixar 3D render, soft lighting` | `Hard plastic toy figurine, NOT soft Pixar` |
| Yeux | Grands iris bruns | `googly eyes — large white sclera, very small dark irises` |
| Rendu | Mat/velours | Brillant rigide |
| Bords | Arrondis/doux | Nets/tranchants |
| Expression | Chaleureuse | Légèrement surprise |

**Règle** : toujours partir du style Hard plastic toy pour la cohérence de la gamme.
