Flip APP_BASE_URL and the on-screen "go to <domain>/setup/..." text in the rendered setup_bg images from pictureframe.edholm.me to wevisto.com. Per the dual-domain migration plan (Option C — server keeps both alive indefinitely), this only affects newly-flashed units; field devices on the old URL keep working against the same backend. Regenerated both panels' setup_bg.bin via gen_screens*.py so the embedded URL in the on-screen QR overlay text matches the firmware's runtime poll URL.

Generate 1200×1600 portrait setup-screen backgrounds for the Waveshare
|
||
13.3" Spectra-6 panel.
|
||
|
||
Layout mirrors the 7.3" gen_screens.py (yellow header + instructions +
|
||
QR codes) but adapted for portrait: a single yellow header band on top,
|
||
then a two-column body — instructions + manual QR on the left, the two
|
||
runtime QR codes on the right. No orientation chooser (13.3" setup is
|
||
portrait-only — see project memory).
|
||
|
||
Run from the firmware/ directory:
|
||
python3 scripts/gen_screens_13e6.py
|
||
|
||
Exports the QR overlay constants the firmware uses to overlay the
|
||
runtime QR images on the static .bin backgrounds; the driver must hold
|

the same numbers.
