/* ==========================================================================
   halle-crime.de – Karten-App
   Designsystem (Redesign 2026-06-28):
   - Karte randlos als unterste Ebene; Bedienelemente schweben als wenige
     Glasflächen darüber (Header, Seitenpanel/Sheet, Info-Panel, Leaflet).
   - Eine Bedienvokabel: Segmented Controls (.chips) + Listenzeilen + 2 Button-
     Rollen (primär/sekundär). Konzentrische Radius-Skala statt Radien-Mix.
   - Farbe kodiert die Ober-Gruppe (4 Anker aus categories.py), die Glyphe die
     Kategorie. Keine Verläufe, kein Glow, keine Deko-Emojis.
   - Fallbacks: ohne backdrop-filter (und bei reduzierter Transparenz) werden
     die Glasflächen opak – Funktion vor Effekt.
