- nginx: client_max_body_size 10m (limite par défaut 1 Mo bloquait les images) - icons.go: import _ golang.org/x/image/webp et image/gif pour décoder WEBP/GIF - index.html: retire SVG de l'accept (serveur le rejette) et corrige le hint - popups.js: try/catch autour de uploadIcon → message d'erreur visible dans le hint pendant 4s si l'upload échoue ; reset du file input pour re-sélectionner le même fichier ; rafraîchit l'img de la tuile avec cache-busting après succès Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
