/* PLAN.md 7.1 (SPEC.md §16): app shell theming. Light/dark via CSS custom
   properties keyed off [data-theme] (set by wwwroot/js/theme.js — see its
   own comment for why this is JS interop rather than pure Blazor), plus a
   configurable --accent custom property the org's admin sets (Phase 7.5's
   branding endpoint, wired at startup via OrgBrandingService). Logical
   properties (margin-inline-start, not margin-left) throughout so the RTL
   scaffolding SPEC.md §16 asks for actually works once a right-to-left
   culture exists, not just in principle.

   Audit finding ("premium/2026, not 2000"): visual pass across the whole
   sheet — refined color palette (softer neutrals instead of flat grays),
   card surfaces on shadow rather than heavy borders, a real type scale,
   consistent radius/shadow tokens, table/nav polish, smoother transitions.
   Every existing class name and custom property is unchanged — this is a
   styling pass, not a markup rewrite, so every .razor file that already
   references .btn/.campaign-table/.stat-card/etc. needed zero changes. */
