/* ---------- Dark theme ----------
   Not an inverted light theme: bg/card match the Flutter app's own
   AppColors.backgroundDark/surfaceDark (#0F172A / #1E293B) for a
   consistent brand across web and app.

   --accent itself (button fills) stays the exact same #2563eb in both
   themes — white text on it is 5.17:1 either way, so there was no
   reason to touch it. --accent-text is the one token that does change:
   it's what every *text*/icon/border use of the brand blue reads from
   instead, because #2563eb measures only ~2.8:1 as foreground text on
   the #1e293b card — below AA. #60a5fa fixes that (5.75:1 on card,
   7.02:1 on bg) without inventing a second brand color.
   --accent-hover lightens instead of darkens in dark mode (the
   opposite direction from light mode) since darkening a button here
   would make it recede into the dark page instead of lifting off it —
   the conventional dark-UI hover direction (Stripe/Linear both do
   this). It's momentary/interactive-only, so its slightly-under-AA
   3.68:1 with white text is an accepted trade-off, not an oversight.
   success/warning/danger are shifted one Tailwind step lighter
   (-400/500) for the same as-text-on-dark-surface reason. */
