/* ==========================================================================
   Fort Kovant UI kit — design tokens + reusable components (v3, 2026-09-24)

   Distilled from the pieces that landed well (home practice grid, About page,
   modern header, footer). Build new sections from these tokens/classes rather
   than one-off values. Documented in docs/00-design-system.md.
