/* ==========================================================================
   Dark theme — auto-selected from the browser/OS (prefers-color-scheme) by
   default; a manual toggle (site.js) can force either theme via
   [data-theme], persisted in localStorage, and always wins over the system
   setting in both directions. Only the semantic paper-, ink- and border-
   token families flip — the brand hues (navy-, teal-, amber-) stay fixed in both themes.
   The .section-dark islands are a separate, permanently-dark surface built
   from those fixed hues; they use --paper-0-fixed/--paper-50-fixed (defined
   once, above, never flipping) for their own text rather than these
   flipping tokens, which would otherwise go dark-on-dark once this block
   activates - that combination was a real, confirmed contrast bug (WCAG
   ~1:1, effectively invisible) fixed alongside this one.
   ink-400 is bumped further than a simple flip (matching ink-500's value)
   because ink-400's own base value already fails WCAG AA in light mode
   (checked and confirmed 3.1-3.5:1 against every paper-* background, an
   existing gap this pass doesn't otherwise touch) - flipping it verbatim
   would carry that failure into dark mode too (2.75-3.93:1), so dark mode
   gets a value that actually passes (4.6-7.3:1) instead.
