/* Colour lives here, not in the state machine (docs/state-machine.md section 3).
   Each state swaps a small set of tokens; nothing else in the sheet knows the
   difference between "normal" and "over six hours".

   The ramp is deliberate: neutral, then green when the feed is due, then amber,
   then red. Green reads as "go" rather than as an alarm, which is what the Feed
   due state means — the feed is wanted, nothing is wrong.

   Dark by preference, because the design constraint is a parent at 3am (§1) and
   a white screen at that hour is its own small cruelty. */
