/*
 * Design v3 — warstwa „front”: nagłówki zakładek, ekran logowania / wyboru świata, onboarding, dostępność.
 * Ładowany po arkuszach bazowych; reguły konkurujące z arkuszami funkcji doładowywanymi dynamicznie (account.css, economy.css…)
 * mają prefiks `html body`. ui/front.js przenosi <link> tego arkusza na koniec <head>, więc i tak wygrywa kolejnością.
 * Zdjęcia nagłówków (img/photo/*.jpg) są tłem WYŁĄCZNIE pseudoelementów widocznych paneli, zawsze pod gradientem (kontrast AA).
