   Fitness Vow — shared base styles
   Used by every public/account web page. Page-specific styles live in their
   own files (e.g. account.css, fees.css). Keep this file purely about:
   - design tokens (CSS variables)
   - reset / typography
   - nav + hamburger drawer
   - footer
   - shared primitives (buttons, cards, msg banners, spinner)
