/* =============================================================================
   YogaRabble — app.css overlay (v2)

   Loads AFTER app.css. Adds:
   - Pill buttons for primary CTAs (Option B: primaries pilled, utilities rounded).
   - Mobile hamburger nav with slide-in drawer.
   - New utility classes that replace common inline-style patterns.
   - Generous corner radii on cards and stat tiles.
   - Fixes the cramped mobile nav on phones.

   Removable: deleting the <link> to this file restores the previous look exactly.
