Map-Bilder und Seitenwahl mit Emblemen

Map-Bilder aus ghostcap-gaming/cs2-map-images lokal als WebP gespeichert
(npm run images lädt und verkleinert sie). Bilder in Veto-Kacheln,
Pool-Vorschau, Serie und Seitenwahl; CT/T-Embleme aus client/public/sides
mit Ersatzsymbol, falls die Dateien fehlen.

+### Bilder für Maps und Seitenwahl

+- **Map-Bilder** liegen lokal unter `client/public/maps/<map>.webp` (960 px breit, je ca. 50–90 KB). `"image"` in `map-pools.json` verweist darauf. Neue oder fehlende Bilder lädt `npm run images` von [ghostcap-gaming/cs2-map-images](https://github.com/ghostcap-gaming/cs2-map-images), verkleinert sie und trägt den Pfad ein (`npm run images -- --force` lädt alle neu). Die Bilder stammen aus dem Spiel; die Rechte liegen bei Valve. Ohne Bild zeigt die Kachel ein Muster in der Map-Farbe.
+- **Seiten-Embleme** für CT und T liegen unter `client/public/sides/ct.png` und `client/public/sides/t.png` (quadratisch, z. B. 256×256). Fehlt eine Datei, erscheint ein schlichtes Ersatzsymbol.
+- Bestehende Matches behalten die Map-Liste, mit der sie erstellt wurden. Neue Bilder erscheinen in neu erstellten Matches.
+
 > Die mitgelieferten Map-Pools entsprechen dem Stand der Entwicklung. Valve ändert den aktiven Map-Pool regelmäßig. Map-IDs bitte gegen die eigene Serverinstallation prüfen. Eine Map, die nicht existiert, führt zu „Konfiguration fehlgeschlagen“ mit Meldung.
