/* ---------- Toasts ----------
   A card on the app's own surface with a coloured icon chip and an accent edge, rather
   than a solid block of colour: it reads as part of the panel, stays legible in both
   themes, and leaves room for the message to actually be read. Auto-dismiss is shown by
   the progress bar and pauses while the toast is hovered or focused. */
