Booting interface
ESP32 DoomsDay began as one portable tool and kept absorbing better questions: Could it navigate offline? Host its own portal? Install apps? Recover from a broken update? Teach a module before depending on it?

Storage, maps, sensors, navigation, apps, and recovery should keep working when the cloud does not.
The interface shows state, apps declare permissions, radios release ownership, and destructive actions ask clearly.
Documented packaging, expandable buses, and an app store turn a finished device into a starting point.
