Punkt 6: MapLibre rendert die Compact-Attribution offen (maplibregl-compact-show + open) → voller Text '© OpenStreetMap contributors' immer sichtbar. Neuer Helper MapGLStyle.collapseAttribution() entfernt die Klasse/open nach dem Hinzufügen → nur noch das ⓘ, der Text erscheint erst auf Klick (rechtlich nach ODbL ausreichend). In map-gl-mini.js (Seitenkarten) + map.js (zentrale Karte) verdrahtet. Punkt 7: poison.js + lost.js hatten UNTER der Karte zusätzlich ein hartkodiertes '© OpenStreetMap-Mitwirkende' — doppelt zum Karten-ⓘ. Entfernt (+ ungenutzte .lost-map-attribution CSS-Klasse). Verifiziert: osmTextLeafCount 2-3 → 1, compactShown true → false.
