The Nano's periodic full redraw blocked for ~0.8 s. A frame that arrived
meanwhile overflowed its 64-byte serial buffer; lost bytes in a bitmap
shift the rest of the image (picture moved up), and diff frames never
repaired it.
- Nano: all drawing (frames, effects, the dot refresh) runs from update()
in ~1 ms slices; the refresh pauses while a frame is received or shown
- New commands: C (reply with the image checksum) and I (refresh minutes,
EEPROM)
- ESP32: NanoMonitor asks for the checksum after frames and sends the whole
image again on a mismatch, missing answer or Nano restart; counts ERR
replies. Periodic whole-image resync.
- Settings: "Dot refresh" and "Image resync" intervals (settings v5,
v4 records are migrated)
- System tab: loop timing, free memory, frame check counts
- test_driver: the real driver against a simulated panel

- README is the overview; web UI, pages, Home Assistant, how it works,
wiring, Nano over WiFi and the recovery app have their own page in docs/.
- docs/web-ui.md has a screenshot of every tab, made with headless Edge by
tools/make_webui_screenshots.py.
- The web UI opens a page in the editor with #pages/<name>. Version 2.7.2.
- The reply wire is fitted (flashing the Nano over WiFi works).

tools/make_page_screenshots.py asks the ESP32 to draw every page (with the
current Home Assistant values) and writes them as PNG in the style of the web
UI's live view to Pictures/pages/.
