   PASS 7–9 — one-screen trainer, coach card, top drawer, XP, progress card, review fixes   (was css/app-v7.css)
   ################################################################ */

/* =================================================================
   PASS 7 (2026-09-25): ONE SCREEN. Trainer = header · coach card at eye
   level · board sized to the space left · bottom action bar. Nothing
   scrolls. Coach text is clean white with one highlighted word. XP pops,
   then flows into a real level bar. Drawer across the full width, board
   slides down. Loaded last.
