/* ---------- Design tokens ----------
   THEME COLORS: the 10 primitives below are the entire palette.
   In the Jekyll build they're overridden by _includes/theme.html,
   which reads the active preset from _config.yml (theme:) and
   _data/themes.yml. Everything else (borders, glows, gradients,
   card backgrounds) is DERIVED from these via color-mix(), so a
   single theme swap recolors the whole site — light or dark.
   Defaults here = the "midnight" dark theme (fallback if no Jekyll). */
