/* =============================================================
   THESIS BOARD
   A machine for remembering what an idea said before reality
   had the chance to answer it.

   Status palette validated against the board surface (#161614)
   with the dataviz six-check validator, all-pairs, dark mode:
     #1baf7a / #c98500 / #9085e9 / #d03b3b  -> ALL CHECKS PASS
     (worst CVD dE 9.9 deutan, worst normal-vision dE 16.9)
   The neutral #898781 is deliberately achromatic: "no signal".
   Every status also carries its own word and its own glyph, so
   colour never carries the meaning by itself.
