/* ==========================================================================
   base.css — the grid, utilities and form/button components this app uses.
   ==========================================================================

   The templates were written against Bootstrap class names (a hangover from
   the original Wt build, where Bootstrap arrived with WBootstrap5Theme).
   Rather than pull in the whole framework for ~80 classes, this file
   implements exactly the subset in use: a 12-column flex grid, the spacing
   and flex utilities, buttons, forms, cards, alerts and list groups.

   It is deliberately small and self-hosted — no CDN, so no CSP exception,
   and nothing render-blocking beyond one file.
