   (green/amber/red/gray via the --c custom property set inline per card),
   not an arbitrary per-line color like the reference — these are 5
   identical inverters, not 6 distinct factory lines, so status is the
   meaningful signal. Light-mode colors match .dev-card/.dev-metric's
   existing palette; dark mode follows this file's established convention
   of hardcoded light defaults + an html.dark override block using the
   existing --color-* tokens (those tokens are only ever defined inside
