/* ============================================================
   FinacctERP UI theme v6 - Material Design 3 (content section)
   - Shell (sidebar menu + top bar) keeps the v5 reference look:
     detached rounded panels, blue-gradient topbar, white 260px
     sidebar with 35px glow, menu hover #6c757d -> #00327d.
   - Content section (article.content + overlays it renders)
     uses a full MD3 token system: tonal color scheme generated
     from the brand navy seed #00327d (Material color utilities,
     baseline tone mapping), MD3 type scale, shape corners,
     elevation-as-tonal-surface, MD3 motion easing, state layers.
   - Legacy v5 variable names are re-declared inside
     article.content so the existing page-scoped stylesheets
     resolve to MD3 roles automatically; the shell keeps the
     original values.
   - Theme toggle: body.dark-theme (user-controlled, persisted);
     auto dark also honored on first paint via prefers-color-scheme.
