 * /virtualni-realita/hygiena-headsetu · /virtual-reality/headset-hygiene
 * Komponenta: src/components/pages/virtual-reality/hygiene/page.tsx, načítá se přes <PageStyles name="vr-hygiena" />.
 * Čisté CSS (není zpracované Tailwindem), všechny třídy s prefixem vh-.
 *
 * Web: úvod → list manuálu jako karta → proč na tom záleží.
 * Tisk: jen list (.vh-sheet) na jedné A4. Uvnitř listu jsou rozměry v em → tisk mění jen font-size listu.
 * Po úpravě textů v content.<locale>.ts zkontrolovat náhled tisku (Ctrl+P), že se list vejde na jednu stranu.
