+Status: Functional MVP
+
+Implemented:
+
+- Boot screen while connecting to Cargo ESP AP
+- Dashboard version display on boot screen
+- WiFi client connection to Cargo ESP
+- HTTP API polling via `/api/v1`
+- Field-filtered status polling with `/api/v1/status?fields=battery,temps,relays`
+- Relay control via HTTP POST
+- Dynamic relay button layout designed to scale up to 6 outputs
+- State-colored relay buttons with dimensional styling
+- Battery SOC gauge
+- Charge/discharge current display
+- Runtime estimate while discharging
+- Time-to-full estimate while charging
+- Idle state when current is near zero
+- WiFi signal strength display
+- Cargo ESP connectivity indicator
+
+Planned next work:
+
+- Temperature card redesign
+- Swipe/page navigation
+- Battery detail page
+- Vehicle data page
+- CAN/OBD-II integration
+- BNO085/BNO086 tilt visualization
