# Design System: ElevenLabs — Do's and Don'ts

## Do

- Use Waldenburg weight 300 for all display headings — the lightness IS the brand
- Apply multi-layer shadows (inset + outline + elevation) at sub-0.1 opacity
- Use warm stone tints (`#f5f2ef`, `rgba(245,242,239,0.8)`) for featured elements
- Apply positive letter-spacing (+0.14px to +0.18px) on Inter body text
- Use 9999px radius for primary buttons — pill shape is standard
- Use warm-tinted shadows (`rgba(78,50,23,0.04)`) on featured CTAs
- Keep the page predominantly white with subtle gray section differentiation
- Use WaldenburgFH bold uppercase ONLY for specific CTA button labels

## Don't

- Don't use bold (700) Waldenburg for headings — weight 300 is non-negotiable
- Don't use heavy shadows (>0.1 opacity) — the ethereal quality requires whisper-level depth
- Don't use cool gray borders — the system is warm-tinted throughout
- Don't skip the inset shadow component — half-pixel inset borders define edges
- Don't apply negative letter-spacing to body text — Inter uses positive tracking
- Don't use sharp corners (<8px) on cards — the generous radius is structural
- Don't introduce brand colors — the palette is intentionally achromatic with warm undertones
- Don't make buttons opaque and heavy — the warm translucent stone treatment is the signature
