   VECNINE LAB — COMPONENT LIBRARY
   Reusable building blocks for Lab and Lab Pro work surfaces.
   Pattern: prefix `lc-` for "lab component". No clashes with
   existing `vn9-` (nav) or page-local classes.

   Design philosophy:
   - Tighter line-heights than marketing pages (1.5 not 1.85)
   - Smaller heading sizes (16-22px, not 32-58px)
   - Higher information density
   - Color encodes meaning (type / center / Hornevian), not decoration
   - Sentence case, never all-caps inside content
   - One spacing scale, one radius scale
