/* ═══════════════════════════════════════════════════════════════════════════
   THE MACHINE — terminal design system
   Mission-control CRT: near-black surface, phosphor readouts, boxed panels.

   COLOR JOBS ARE KEPT SEPARATE. This is the rule that keeps a dense board
   readable, and it is not a matter of taste:
     · STATUS  (--good/--warn/--alarm) is reserved for gauge bands and lights.
       Never reused as a series color. Always shipped with the band WORD and a
       glyph, never color alone.
     · DIVERGING (--div-pos ↔ --div-neg with a NEUTRAL GRAY midpoint) encodes
       polarity on equilibrium and stance bars. Deliberately cyan/amber, not
       green/red, so it cannot be confused with status.
     · CATEGORICAL (--cat-1..4) is for multi-series detail charts only, assigned
       in fixed order and never cycled. A 5th series folds into "Other".
     · INK carries all text. Text never wears the data color — the colored mark
       beside it carries identity.

   Every color below was machine-validated, not eyeballed:
     categorical  → dataviz validate_palette.js, dark mode, surface #05080a:
                    lightness band / chroma floor / CVD separation /
                    normal-vision floor / contrast — all PASS.
     status + ink → WCAG contrast vs surface (phos 15.1, amber 11.0, alarm 5.8,
                    ink 16.7, ink-2 8.0 — all clear AA text).
   Re-run the validator before changing any of them.
