/* ============================================================================
   FUNDIS shared design tokens - THE single source of truth for colour, type,
   radius and motion across every surface: the admin SPA, the worker PWA, and
   the standalone EJS portals (risk, incidents, complaints, SA, shiftplay).

   HOW TO TUNE (the whole point): change a value ONCE here and it flows to every
   surface that loads this file. To restyle the brand accent, edit --accent (and
   its dark override) and nothing else.

   These values MIRROR public/fundis-roster/styles.css :root (the admin SPA still
   defines its own copy for now). Keep the two in step until the SPA is switched
   to @import this file; see docs/DESIGN-SYSTEM.md.

   Dark mode: driven by html[data-theme="dark"] (same hook as the SPA and the
   portals' a11y.js widget). Everything is defined through tokens so a surface
   that uses var(--bg)/var(--ink)/... gets dark mode for free.
