   DARK MODE — guide reading pages adopt the Revetti glow default.
   The base rules above are the light-mode fallback; .mode-dark on
   <html> flips surfaces + text to INK/BONE per Design Brief v4.1.
   guides.css originally hard-coded raw tokens (--bone/--ink/
   --graphite), so it could not respond to .mode-dark — these
   overrides map each guide element onto the dark-safe semantic
   tokens. NOTE: GRAPHITE text on INK is prohibited by the brief,
   so dark body copy uses --text-secondary (ASH), never graphite.
