/* ============================================================
   Crafta — website/styles.css
   Canonical against DESIGN.md (2026-05-28).

   Updates 2026-05-28 (this revision):
   - Phosphor icon system per §9 (sizing tokens, alignment rules).
   - Display-italic wght 460 applied wherever italic appears at
     display sizes (stat-unit, problem-conclusion em, audience
     tagline em, contact accent) per §2 + Wordmark §4.
   - :focus-visible ring per §14 (2px solid accent, 2px offset).
   - Editorial composition: section kicker ("Field note NN"),
     figure-style stats, sequential phase timeline.
   - Footer wordmark gets size-appropriate tracking per §4 size table.
   - Hero metadata strip (status pill row) per §12 component set.

   Foundation: typography (§2), color (§3), wordmark (§4),
   spacing (§5), radius (§6), grid (§7), iconography (§9),
   motion (§11), accessibility (§14), voice (§15) in DESIGN.md.
