Server: domain (entities, value objects, ports), protocol (postcard wire types), application (config service, data projection), adapters (config-memory, tcp-server), bootstrap (composition root with fake data). Client: client-domain (layout engine, render tree, HAL ports), client-application (message handling, repaint commands), adapters (tcp-client, display-terminal), client-desktop (end-to-end working). ESP32: client-esp32 firmware with ILI9341 display over SPI, WiFi networking. Display test verified on hardware — landscape orientation, text rendering works. 60 workspace tests, all passing.
