/* Colour tokens — the palette in the brief (§8), with one pairing adjusted.
   Every colour in every component reads one of these custom properties; no
   hard-coded hex exists outside this file (acceptance #16).

   CHANGED FROM THE BRIEF, as §8 requires be reported: --ink-3 in both
   themes. It carries metadata at 9–13 px — "2d late", "EVERY 6 MONTHS" —
   so the 4.5:1 body-text threshold applies to it, and it was at 2.37:1 in
   light and 3.56:1 in dark. Now 4.66:1 and 4.66:1 at worst, chosen with
   margin so a rounding difference cannot drop it back under. Hue unchanged;
   only lightness moved.

     light  #949B94 -> #646964
     dark   #6E766F -> #838983

   --ink and --ink-2, which carry actual prose, always passed and are
   untouched. tests/stage3 computes these ratios so they cannot drift.

   The six domain pigments (time, exec, body, mind, people, career) carry
   meaning and appear only as dots, left borders and markers — never as
   background fills. --signal is reserved for the now-line, overdue items
   and expiry alerts, and appears nowhere else. */
