/* Zawartość przypinamy razem z powierzchnią. `.btn-primary` (kit.css) jedzie
   z --primary, a ciemny motyw rozjaśnia ten pomarańcz do #F26430 i przy okazji
   miesza krawędź candy z bielą - na białym banerze biały napis na nim spada
   do ~2,8:1, a cień robi się jaśniejszy od lica. Przycisk nie znika jak w V2
   (tam --btn-bg w ciemnym to czysta biel), ale przyczyna jest ta sama, więc
   i lekarstwo: przypięte tokeny na banerze, a nie przepisane właściwości
   przycisku. Link z reguły wyżej dostaje to samo.
   Wartości muszą być jasnymi wartościami z v2/bridge.css (to on, nie
   tokens.css, ma ostatnie słowo na stronach legacy) - inaczej przypięcie
   przemalowuje baner także w jasnym motywie. */
