/* ============================================================
   Zakładka „Kategorie ofert" — drugi krok odświeżenia frontu.
   Wszystko SCOPED pod #tab-categories. Część patternów (form-card,
   hint, btn, data-table, state-*, toast) jest zduplikowana z
   similar.css — refaktor do components.css po 3. zakładce.
   Flow „sezonowość" zostaje w starym wyglądzie (osobny krok).
