+
+Current dashboard target:
+
+- Waveshare 5" ESP32-S3 Display
+- WiFi client
+- Connects to cargo ESP32 AP
+- Uses existing HTTP API
+- Planned LVGL implementation
+
+Important:
+
+- ESP32 cargo controller remains source of truth.
+- Dashboard is a client only.
+- Existing UART protocol remains supported but is no longer the primary dashboard transport.

+## Dashboard Architecture Update
+
+Primary dashboard architecture is now:
+
+Cargo ESP32 Controller
+→ WiFi AP/STA
+→ HTTP API
+→ WebUI
+
+Dashboard Client:
+→ Waveshare 5" ESP32-S3 Display
+→ Connects to cargo ESP32 over WiFi
+→ Consumes existing HTTP API
+→ Planned LVGL-based dashboard UI
+
+The Raspberry Pi Pico 2 W dashboard path is no longer the primary implementation target. UART JSON remains supported as an optional interface for future expansion, debugging, or alternate dashboard hardware.
