/* ---------------------------------------------------------------------------
   Verejná rezervačná stránka /reserve (docs/architecture.md, bod 10).

   Načítava sa VÝHRADNE z OrderCreatePage.razor cez <HeadContent>, nie globálne
   v App.razor - po odchode zo stránky Blazor <link> odstráni. Preto sa tu smie
   prepísať aj `body`. Triedy majú prefix rv-, aby sa nezrazili s adminom.

   Farebná schéma je tenantova: stránka dostane dve premenné inline zo servera,
     --rv-ac  farba tenanta z Nastavení
     --rv-on  farba textu na nej (tmavá alebo biela, dopočítaná v TenantTheme)
   a všetko ostatné - svetlé podfarbenie, okraje, prstenec zamerania - sa z nich
   odvodí tu cez color-mix. Žiadna ďalšia farba sa per tenant neukladá.

   Ikony kategórií (Ionicons) sú v icons.css, načítanom globálne.
