/* ==========================================================================
   SETTINGS · THEME DARK — "After Hours / the humidor". The same reading room
   once the staff have gone home: a single brass lamp, the cordovan club chair,
   the humidor open, oxblood now reading as wine in lamplight. NOT black — black
   is austerity, the opposite of the decadence Epidaurus trades on. This is deep
   tanned leather and espresso, lit from within.

   It re-pitches the ENTIRE look by overriding ONLY the raw pigments from
   _color-palette.css (plus the two shadow tints that can't auto-flip). Every
   semantic role in _color-semantic.css is a color-mix() derivation of these, so
   washes, keylines, band fills, muted text and the inverse CTA all follow for
   free — exactly as the light theme re-pitches from one file.

   The paper stack INVERTS its depth logic: in daylight a raised sheet is
   *lighter* than the page and a sunken well *darker*; under the lamp a raised
   surface is the one *closest* to the light (lighter), the well recedes (darker).

   Sorts last among the colour partials (after _color-palette + _color-semantic)
   so the prefers-color-scheme override at :root wins on source order; the
   [data-theme] selectors out-specify regardless. This file holds NO component
   rules — it is settings only.

   PDF NOTE: dark mode is a screen concern. The print pipeline (lib/pdf/print.css)
   is a deliberately separate, always-light document and must never read these.
