/* =========================================================================
   POLITYKA backdrop-filter (render-safety + wydajność)
   -------------------------------------------------------------------------
   Chromium ma bug kompozytora: warstwy backdrop-filter potrafią NIE odświeżyć
   się (treść renderuje się pusta do scrolla/hover) — głównie nad animowanym
   rozmytym tłem oraz w poddrzewach przełączanych z display:none (np. taby,
   modale). Każda dodatkowa warstwa to też realny koszt GPU.

   Optimum: backdrop-filter TYLKO na stałym chrome (sidebar, topbar, logo) —
   nieliczne, malowane przy starcie (nie z display:none), i to nad nimi
   przewija się treść, więc frost ma tam sens. Cała reszta (karty, tabele,
   badge, inputy, przyciski, modale, dropdowny) używa półprzezroczystego tła
   bez blur — wygląd „szkła" niosą kolor + obramowanie nad statycznym tłem.
