## Design Principles
- **Low-saturation**: Desaturated, muted tones. No neon, no AI-gradient blues/purples.
- **Minimalist**: Generous whitespace, clean geometry.
- **Warm Neutral Base**: Cream/off-white background (Identity Light) as the canvas.
- **Monochromatic Accents**: Accents are desaturated earth/slate tones, not vivid.

## Typography

### Primary Font Stack
- **Heading / Display**: `Styrene A` (Anthropic proprietary) → fallback `"GT Walsheim"` → `"Inter"` → `"Liberation Sans"`
- **Body / Label**: Same stack at smaller sizes
- **Monospace / Technical**: `"IBM Plex Mono"` → `"Courier New"`

### Font Weights
- Display title: **Bold / 700**
- Section labels: **SemiBold / 600**
- Body / annotations: **Regular / 400**

### System Font Fallbacks (Linux)
When proprietary fonts are unavailable, use:
```python
HEADING_FONT_NAME = "DejaVu Sans"  # or "Liberation Sans"
font_paths = {
    "bold":    "/usr/share/fonts/truetype/dejavu/DejaVuSans-Bold.ttf",
    "regular": "/usr/share/fonts/truetype/dejavu/DejaVuSans.ttf",
}
```

## Brand Do / Don't
- Do: Use Identity Light (`#F5F0E8`) as the poster background.
- Do: Pair Corporate Dark (`#1A1A1A`) for primary typography.
- Do: Keep accents muted and earthy.
- Don't: Use neon, electric blue, or high-saturation gradients.
- Don't: Mix more than 3 accent colors in a single composition.
- Don't: Use white (`#FFFFFF`) as background — use Identity Light instead.
