/* ============================================================
   DARK-mode readability layer
   The light layer above has existed for a while; there was never a dark
   equivalent, so in dark mode — which is what the dashboards actually run in —
   every template fell through to the raw Tailwind palette. Measured against the
   card background (#0a1125):

     .text-gray-500   3.88:1   FAILS WCAG AA        179 uses on the 3 main screens
     .text-gray-600   2.48:1   fails badly           15 uses
     .text-gray-400   7.39:1   passes, but thin at 10-11px

   Client feedback 21 Jul, six separate times: the grey text is too hard to read.
   The cause was not the templates, it was this missing block.

   Remapped by COLOUR CLASS ALONE, deliberately: ~40% of colour usages carry no
   size class in the same attribute (they inherit size from a parent), so any
   size-scoped selector such as `.text-xs.text-gray-500` would silently miss them.

   Hierarchy is preserved — 14.15 > 10.46 > 7.30 — so the visual ranking of
   heading / meta / subtle still reads, it is simply all legible now.
