/* =============================================================================
   METRIK · AR-Erlebnis — Stylesheet
   =============================================================================
   Aufbau (zum schnellen Springen per Suche nach der Nummer):

     1  Design-Tokens .......... zentrale Farben (hier zuerst ändern)
     2  Basis / Reset .......... html, body, Grundeinstellungen
     3  Lade-Spinner ........... #loader / .spinner (bis Seite geladen)
     4  Start-Overlay .......... #start (Logo, Text, „Kamera aktivieren“)
     5  Hinweis-Banner ......... #hint (oben: „Kamera aufs Plakat …“)
     6  Button-Leiste .......... #ui + .btn (Showreel, Leistungen, Termin)
     7  Fehlermeldung .......... #err (helle Hinweiskarte)
     8  MindAR-Overrides ....... Scanning-Rahmen einfärben
     9  Interaktive Ebene ...... Overlays über dem Video (Claim, Hotspots,
                                 FAB-Menü, Video-Controls, End-CTA)

   Farben werden ausschließlich über die Tokens in Abschnitt 1 gesetzt —
   eine Änderung dort wirkt überall.
