   The palette runs one discipline, and everything else follows from it:

     WARM CARRIES STRUCTURE.  COOL CARRIES DATA.

   Copper draws every rule, heading accent, and button — it's the shop that built
   the thing. `--signal` (cool blue) is reserved *exclusively* for figures being
   measured: charts, telemetry values, status lamps. It never appears on a button,
   a border, or a decoration. The moment it does, the page collapses into the same
   dark-mode SaaS look as everything else.

   To check that rule still holds: `grep -n "signal" styles.css` and confirm every
   hit sits on something that is a measurement.
