Letzter Roadmap-Punkt von V3. Foto-basierte Lichtverhältnis-Analyse pro Stellplatz (Cloud Function analyzeLocation) und darauf aufbauende, rein textbasierte Eignungs-Bewertung einer Pflanze (assessPlantFit) — beides ausschließlich auf Abruf, nicht automatisch (Kostenkontrolle, eigener Anthropic-Key). Neue Stellplatz-Detailseite, Verlinkung im Pflanzen-Detail, Erkennung veralteter Bewertungen bei Umzug/Neuanalyse. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
