/* ============================================
   TS Returns - frontend (modal wtyczki)
   Baza neutralna: własne zmienne --tsr-* z fallbackami.
   Akcent (--tsr-accent) dziedziczy z motywu przez --color-button,
   więc przycisk i akcenty same dopasowują kolor sklepu.
   Tło dialogu domyślnie białe (pasuje jasnym motywom);
   ciemny motyw nadpisuje przez CSS szablonu (sekcja override).
