/*
 * [2026-09-13] Przejścia z `.claude/skills/transitions-dev` (Marcin: "spróbuj
 * wykorzystać nowy skill transitions.dev na stronie marketingowej"). Zasady
 * skilla: zmienne `:root` raz, snippety CSS WKLEJONE BEZ ZMIAN (selektory
 * `t-*`, `will-change`, blok `prefers-reduced-motion`).
 * Użyte: Text states swap (04), Icon swap (09), Texts reveal (18), Accordion
 * expand (21), Learn more hover (24), Tabs sliding (16) + tokeny ruchu.
 *
 * [2026-09-19] Wydzielone z `home.css` do osobnego pliku - ładowany przez
 * `home_wrapper.php` I `apppanel_wrapper.php`, bo przebudowany uploader
 * (`app/partials/uploader.php`, wspólny dla strony głównej i okna "New
 * transfer") używa Tabs sliding i Accordion expand w obu miejscach.
