/* ============================================================
   LIGHT/DARK MODE
   :root's bare values above are the dark palette - this site's original,
   and still the overall fallback, look. Light takes over two ways:

   1. No explicit preference stored + the OS/browser prefers light -> the
      prefers-color-scheme media query below (this is what makes the
      DEFAULT auto-follow-system-settings behavior work with no JS involved
      at all).
   2. An explicit preference IS stored (via the nav's toggle button, see
      js/theme.js) -> the inline <script> at the top of every page's <head>
      sets data-mode="light"|"dark" on <html> before first paint (to avoid a
      flash of the wrong theme), and the two attribute rules below apply -
      these win over the media query in both directions, which is why the
      media query's guard is ":not([data-mode="dark"])" rather than nothing.

   Same duplication pattern as the per-phase themes above: every rule
   elsewhere reads var(--bg)/var(--text)/etc., so retheming here needs no
   changes anywhere else in this file.
