Pueo 0.4.50 - source archive

  tools/build.sh setup      one-time, installs a pinned toolchain (~1 GB)
  tools/build.sh            compile
  tools/build.sh merge      single flash image at offset 0
  tools/build.sh upload COM7

Builds for the 3.5" ESP32-3248S035R, which is the only panel this supports.

The 2.8" ESP32-2432S028R was supported up to 0.4.13 and is not any more. It
was built every release and never booted, so what was published for it was
an image that compiled, not one that worked. Those releases are still there
and still carry their digests, and 0.4.13 is the last of them.

Requires arduino-cli and Python 3 with Pillow (only for the bitmap tools).

Everything is installed into its own root rather than a global Arduino
install, so it cannot disturb another project. Read the "Things that will
bite you" section of PUEO.md before deviating from the script -- the esp32
core version, the pinned library versions and the toolchain path length are
all load-bearing.

Features inherited from upstream are inherited, not audited. See the status
note in PUEO.md.

tools/history/ holds the one-shot scripts that performed specific refactors,
kept for provenance. They are not meant to be run again and will refuse.
