Vendored and trimmed from microsoft/uf2-samdx1, adapted to the actual ATSAMD21G17D (128 KiB flash / 16 KiB RAM), fixing the flash/RAM-size mismatch that the previously commented-out SAM-BA bootloader target had (it assumed a 256 KiB SAMD21G18A). Builds as a standalone PlatformIO environment (bootloader/platformio.ini), no python2/make dependency. Compiles clean, fits in the 8 KiB bootloader region (7292/8192 bytes). Not yet flashed/verified on real hardware.
