+### Prism multi-view Mushroom dashboard deployed to HAOS
+- **[HA]** Replaced single-column phone view with a 5-view Mushroom dashboard: `home` (chips + greeting + nav + room cards), `living`, `bedroom`, `kids`, `kitchen` sub-views. Each sub-view has back chip, section titles, relevant light/climate/vacuum/appliance controls.
+- **[TECHNIQUE]** File-based YAML dashboards (`mode: yaml` in `configuration.yaml`) cannot be saved via `lovelace/config/save` WebSocket. Deployment method: set `init_commands` on the Advanced SSH add-on via `supervisor/api` WebSocket, split base64 into 180 × 80-char chunks, decoded back to YAML on restart. Verified with `lovelace/config` WebSocket — all 5 views loaded correctly.
+- **[HA]** `kiosk_mode: hide_header: true` applied to hide HA tab bar on mobile.
