/* GLOBAL RESET & BASE STYLES
   ────────────────────────────────────────────────────────────────────────────
   Do 2026-08-08 tej sekcji brakowało faktycznego resetu — niósł go Bootstrap
   Reboot, ładowany zawsze przed app.css. Odkąd landing nie ładuje Bootstrapa
   (nie używa ani jednej jego klasy, a plik jest render-blocking i w 98%
   nieużywany), reset musi stać tutaj.

   Wartości są 1:1 z Reboot 5, więc na stronach `/app` (gdzie Bootstrap nadal
   wchodzi) te reguły tylko nadpisują go tym samym — zero zmiany wizualnej. */
