+JH Photomaton — Interface de gestion
+Raspberry Pi 4 / Les Sapins Du Web (LSDW)
+
+Remplace Node-RED pour :
+  - Contrôle bouton GPIO23 (multi-clic + long press) + relay GPIO12
+  - LEDs WS2812b GPIO18 (35 LEDs) — effets selon état
+  - Galerie publique et galerie admin
+  - File d'attente d'impression (SQLite)
+  - Dashboard admin avec monitoring système
