Subtitle at 18px Inter weight 400, line-height 1.60, letter-spacing 0.18px, #4e4e4e text. Two pill buttons: black (9999px, 0px 14px padding) and warm stone (rgba(245,242,239,0.8), 30px radius, 12px 20px padding, warm shadow rgba(78,50,23,0.04) 0px 6px 16px)."
- "Design a card: white background, 20px radius. Shadow: rgba(0,0,0,0.06) 0px 0px 0px 1px, rgba(0,0,0,0.04) 0px 1px 2px, rgba(0,0,0,0.04) 0px 2px 4px. Title at 32px Waldenburg weight 300, body at 16px Inter weight 400 letter-spacing 0.16px, #4e4e4e."

- "Create an uppercase CTA label: 14px WaldenburgFH weight 700, text-transform uppercase, letter-spacing 0.7px."
- "Design navigation: white sticky header. Inter 15px weight 500. Black pill CTA right-aligned. Border-bottom: rgba(0,0,0,0.05)."

## Iteration Guide

1. Start with white — the warm undertone comes from shadows and stone surfaces, not backgrounds
2. Waldenburg 300 for headings — never bold, the lightness is the identity
3. Multi-layer shadows: always include inset + outline + elevation at sub-0.1 opacity
4. Positive letter-spacing on Inter body (+0.14px to +0.18px) — the airy reading quality
5. Warm stone CTA is the signature — `rgba(245,242,239,0.8)` with `rgba(78,50,23,0.04)` shadow
6. Pill (9999px) for buttons, generous radius (16px–24px) for cards
