 ### Completion Notes List
 
+- ZoneCard utilise `emoji` de MapZone (pas `icon` comme dans la spec originale)
+- SettingsDrawer utilise un lien vers /resume au lieu d'un toggle expressMode
+- ProgressDetail réutilise ProgressBar avec mode compact
+- Toutes les transitions respectent prefers-reduced-motion
