/*
  Praxas Observability — styles.

  Dense ops-dashboard look: system sans, tabular figures in tables and axes only, hairline
  borders, quiet chrome so the data is the loudest thing. Colours are tokens on :root with a dark
  set chosen (not flipped) for the dark surface; the OS setting applies unless the manual toggle
  sets <html data-theme>. Chart series tokens --s1..--s7 are a validated categorical palette
  (adjacent CVD ΔE ≥ 8 in both modes); status tokens are reserved for state and always ship with
  a text label.
