   Dark-first. The intensity heat ramp of the Live gauge (src/ui/live-draw.js,
   SCALE) is the brand palette: blue calm → cyan → green → yellow → orange →
   red → magenta → white hot ("off the charts").

   Design tokens (every other stylesheet should build on these):
     Surfaces   --bg, --surface, --surface-2, --surface-3, --field
     Lines      --border (hairline), --border-strong, --grid, --track
     Text       --text, --text-2, --muted
     Accent     --accent (magenta, ramp stop 94), --accent-2 (hover),
                --accent-ink (text on accent), --accent-soft (tinted bg),
                --accent-glow
     Data       --series (neutral data line), --ramp (the heat ramp as a
                horizontal gradient over 0 → SCORE_MAX = 125), --ramp-1 … --ramp-9 (its stops)
     Status     --good, --warn, --bad
     Shape      --radius (cards), --radius-sm (controls), --radius-lg (heroes)
     Depth      --shadow (floating layers), --highlight (inset top light)
     Type       --font-ui, --font-display, --font-mono
     Motion     --ease-out, --ease-spring, --dur-fast, --dur
     Scores     --sc is set inline on score elements to their ramp colour
   Themes: dark on :root; light under prefers-color-scheme: light, or forced
   with <html data-theme="light|dark">.
