/* ==========================================================================
   FourHeroes design system
   --------------------------------------------------------------------------
   Direction: "logbook after dark". FourHeroes is a private nightly record, so
   the chrome behaves like a bound notebook rather than a dashboard: a quiet
   cool-paper ground, ink text, one deep-teal accent, and a page header that is
   always night. Headings are set in an old-style serif (the voice of a written
   record); every bounded score is set in tabular mono so columns of numbers
   line up.

   Everything below is driven by the tokens in the first two blocks. Change a
   token, not a rule.

   Colour modes
   ------------
   The document always carries an explicit `data-bs-theme` (the inline script in
   base.html sets it before first paint from localStorage, falling back to the
   OS preference), because Bootstrap 5.3 only switches its own components on
   that attribute. The `prefers-color-scheme` block below is the no-JS
   fallback: our own tokens flip, while a handful of Bootstrap's subtle alert
   backgrounds stay light. Keep the two dark blocks in sync.
