/* ==========================================================================
   Dark mode - warm-dim theme + the header theme toggle. Added 2026-06-16.
   The site is token-driven, so dark mode is mostly a re-declaration of the
   core tokens under [data-theme="dark"], plus a few targeted overrides for
   places where --ink was used as a dark *fill* (footer, bright chips) or a
   colour was hardcoded (select arrow, poll dot, marker blend mode).
   st.js sets data-theme to the RESOLVED theme (light|dark) and
   data-theme-pref to the user's choice (light|dark|auto); a no-flash inline
   script in each page <head> sets both before first paint. All dark values
   are WCAG-verified: body text 13.6:1, body links 9.0:1 (AAA).
