/* =====================================================================
   app-design.css — Shared design system for the household platform
   Phase 1 of the UI overhaul. Unifies the whole app on the calendar's
   green "household" aesthetic.

   Contents:
     1. Design tokens (light + dark)
     2. Base / body
     3. Bootstrap refinements (low-risk, visual only)
     4. app-* component library (opt-in, used as pages are converted)
     5. Utilities
     6. Responsive

   Loaded globally via partials/theme-head.ejs AFTER Bootstrap so these
   rules win. Nothing here changes page behaviour — visual only.
