/* ---------------------------------------------------------------------------
   RIGCLEAR — the design system.

   Direct descendant of the RigClear.dc.html canvas: cool steel ground, dark
   slate sidebar, IBM Plex Sans for prose, IBM Plex Mono for numbers and
   micro-labels, Instrument Serif for page titles. Type and spacing run 1.2×
   the canvas (the canvas is a 1440px mock; this is an app people read all
   day) — scaled TOGETHER, per the KATHARINE lesson: a font bump on its own
   overflows every fixed-width column.

   The five status colours are the entire vocabulary:
     cleared  #147D64  green — qualified, compliant, ready to drive
     expiring #8A6A1B  amber — legal today, a clock is running out
     missing  #A8453A  red   — do not dispatch
     review   #2B5FAD  blue  — a human decision is staged
     neutral  #98A1AD  grey  — not applicable / nothing yet
   Nothing else in the product may claim these hues.

   Soft blue ground + dashed edge marks DEMO SCAFFOLDING only — machinery that
   is deleted before launch. The fabricated drivers are NOT marked: they stand
   in for real ones. See CLAUDE.md.
