   QRLAB – základní styly šablony (převzato ze šablony QRLAB-template/styles.css)
   Barvy a rozměry upravíte v :root. Úpravy oproti originálu:
   - fotografie jsou samostatné soubory v assets/img (místo CSS výřezů),
   - šablonová karta .card → .tcard (aplikace používá .card pro panely),
   - obecné třídy .icon/.number jsou omezené na své sekce,
   - logo je SVG (assets/logo-mark.svg) místo znaku ▦.
