/* ===================================================================
   YakTimer marketing / landing page
   Built to WCAG 2.1 AA:
   - 17px readable base, line-height ≥1.5 (SC 1.4.4 resize, 1.4.12 spacing)
   - all body text ≥ 4.5:1 contrast, large text ≥ 3:1 (SC 1.4.3)
   - visible keyboard focus on every control (SC 2.4.7)
   - rem units so text scales/zooms to 200% cleanly
   - reflows to one column with no horizontal scroll on small screens
   Everything is scoped under .yt-home so the app UI is untouched.
