scripts/cardputer-zero/screenshot.py reads the display's framebuffer
over SSH and writes it as a PNG of 320x170, the size the store wants.
It only reads, so it does not disturb the app. JP set up each screen
on the device: the splash, the menu, the Public channel, a contact's
routes, the map, and a packet from the live feed. The listing passes
the store's own metadata check.
