/* ─────────────────────────────────────────────────────────────────────────────
   maps67 admin console — THE stylesheet.

   One file, because `conventions.md` thumb rule #3 is centralize: every colour, radius, space
   and type step is a token declared once at the top and referenced everywhere below. Changing
   the console's density or palette is an edit to the token block, not a hunt through rules.

   UI rules honoured here (conventions.md §UI/UX):
     #1  native look, no emoji — icons come from src/admin/icons.ts, never inline in a view
     #3  fluid, compact-native typography that adapts to viewport
     #7  icon buttons carry tooltips (title attributes) on destructive actions
     #8  spacing from a single scale, so gutters line up at every breakpoint
     #11 colour-theme switching is always present — light/dark, following the OS by default
     #12 data views are modern: sortable-looking tables with filters, not orthodox dumps
