/* ── Dark scheme ─────────────────────────────────────────────────────────
   §3 requires system-native Light/Dark support. Every component already paints with the
   var(--color-*) tokens above, so flipping the surface/text/border tokens here is what actually
   turns the theme over — no component rules are duplicated.

   The header and footer are deliberately NOT re-themed: they are fixed dark chrome in both
   schemes, and their contrast ratios were computed against #0f172a (see the inline notes in
   MainLayout.razor.css). Re-tinting them would invalidate that work for no visual gain.

   Contrast against --color-bg (#0b1220): --color-body ≈ 14:1, --color-muted ≈ 7.4:1 — both
   clear WCAG AA. Note --color-muted-light is unchanged; it was already a dark-surface token. */
