/*
  Design tokens.
  Signature accent (copper) nods to electrical wiring; monospace chrome nods
  to the terminal/CLI work under Skills. Status dots borrow the vocabulary of
  network link lights (built = link up, in design = blueprint blue).
  Contrast checked against WCAG 2.1: text/muted/accent >=4.5:1 on their
  surface in both themes; status colors are decorative indicators (paired
  with a text label, never the only signal) and are checked to >=3:1.
