-cards pin a dark text class alongside every pale background so
-the card stays legible regardless of theme:

-if (order.status === 'ready')  return 'bg-amber-1 text-grey-9'
-if (ageSec > 900)              return 'bg-red-1 text-grey-9'

-return ''   // theme-default branch keeps q-card's own text color
