- Preview thread : poll uniquement quand ecran capture actif, keepalive 30s sinon
- Sequence boot Canon : power cycle relais si absent USB au demarrage
- Veille auto 30min : Canon coupe par relais apres inactivite, reveil au preview_start
- Stats diagnostic /api/canon/stats : keepalive, preview, captures, connexions
- Escalade reconnexion adoucie : pas d'USB reset les 2 premieres tentatives
- Hard reset relais 10s (resistance decharge 990ohm sur dummy battery 8V)
- Gestion fin evenement : date_fin + bouton terminer + guard 403 impression
- Compteur base sur min(papier, ruban) avec cap evenement optionnel
- Pre-eclairage countdown : projecteurs ON 3s avant capture pour mesure expo
- Canon _configurer_init() : ISO 800, drivemode Single, viewfinder, EXIF preserve
- Admin : detail evenement, compteur consommables, galerie impression
