   8) Utility Notes for Consistency (non-visual)
   ======================================================================== */
/*
  - Use .section, .section--soft, .section--muted for clear content blocks.
  - Use .card for service cards on Eventová nabídka and detail pages.
  - Use .booking-cta as global booking section before Kontakt.
  - Use .hero with .hero__bg and .hero__overlay on main page heroes.
  - Navigation toggle relies on .nav--open class added via JS.
