/* ════════════════════════════════════════════════════════════════
   NAADI AI — PROFILE (profile.css)
   ─────────────────────────────────────────────────────────────────
   Loaded LAST in app.html, after practice-v2.css. Adds only .pf-*
   classes — nothing here overrides an existing selector.

   SURFACE: the app shell is light (white cards on --s50), so Profile
   is light too. The one dark element is the gradient hero at the top,
   which is the same blue→teal ramp used everywhere else. No new
   colours. Red appears nowhere: it stays reserved for traps and
   wrong answers.
