## New
- "Welcome" screen shown on first-time setup (before touch
calibration), with the splash screen's animated radar graphic and a
Start button.
- The "Setup complete" screen now counts down 7 seconds with a button
matching the Welcome screen's style, then automatically continues
into the app (previously required a tap).
- System menu "Backup & Reset" page (Backup, Restore, and a new
"Reset settings" option that wipes the on-device data and re-runs
first-time setup - useful for testing or handing the device to
someone else).
- Touch calibration targets are now green mini radar reticles instead
of red crosshairs.
## Improved
- The SD card's data folder is now only created after tapping Start
on the Welcome screen, instead of on every boot regardless.
- Flash partition layout changed to free up roughly 850 KB of
firmware space (no OTA update slot needed, since firmware is always
flashed via cable/USB) - lowers flash usage from ~95% to ~59%.
## Fixed
- The Start button and the WiFi scanning screen now show a loading
indicator instead of appearing frozen during SD-card/WiFi
operations.
- A touch-input bug during first-time setup that could corrupt touch
calibration and cause taps to land on the wrong on-screen element
afterward (most noticeable in the WiFi network selection list).
