/* ── Dark theme ──
   Background/text/border tokens shift with the theme. The accent colors
   themselves (--red/--success/--warning/--danger/--info/--purple) stay
   identical in both modes on purpose — they're the ones used as *solid*
   fills with white text (buttons, solid badges) and changing them would
   break that contrast. Only the paired "-light" fill tokens (filled boxes:
   alerts, tags, badges) and their "-text"/"-border" companions (the text/
   border color used *on top of* that fill) get dark-mode overrides, since a
   pastel light-mode fill with dark accent text has no readable dark-mode
   equivalent unless the fill itself darkens and the text lightens together. */
