/* BARBAROS — credits-premium.css · top-up model 5 "Montant libre" (owner choice, prototypes/topup-models.html)
   A centred modal on desktop, a bottom sheet under 600px. Surfaces, ink and accent come only from the
   --buld-* tokens (Signature dark palette: page #1F1E22 · surface-2 #29272D · elevated #3A3640 ·
   elevated-2 #45414C · hover #4F4A57 · cta #4C9DFF), so the light theme and the other palettes follow.
   Sits between drawers and the confirm dialog (BuldUX.confirm must stack above it).
   Collision list: the legacy modal #apBillingModal is never shown (#1); every class is `tu-*` and avoids
   the painter substrings (card, -chip, -tag, badge, status, pill, -box, block, -tile, -list, -label). */
