   The card-header is a *label*, not a banner: light surface, hairline, dark
   grey small type.  Colour on this site is reserved for meaning (red = rating,
   green/red/yellow = verdict), so a saturated header competes with it.
   This is the same treatment `.problem-meta-card .card-header` already used.
   Judge-status headers (.card-uoj-*) and `bg-*` utility headers are more
   specific, so they keep their own colours.
