   Palette is deliberately single-theme (dark) — this is a terminal tool
   for people who live in dark-mode terminals, not a page that needs to
   also look right in daylight mode. Every semantic color (conflict /
   confirmed / possible) is lifted directly from conflict-check's own
   CLI output, so the site's "brand colors" are literally the product's
   real vocabulary, not a decorative palette invented for marketing.
   `signal` is the one color that ISN'T semantic — the only accent spent
   on brand rather than meaning.
