First per-board binary. rust/pm-kit/ is a minimal rp235x-hal firmware that blinks GP25 on the Pico 2 — proves the toolchain, RP2350 boot block (ImageDef), memory layout, and flash before we add any drivers. - src/main.rs + memory.x + build.rs + .cargo/config.toml: rp235x-hal blink, builds for thumbv8m.main-none-eabihf. - build.sh + uf2.py: one command builds the ELF in the container, objcopies to a raw image, and packs pm-kit.uf2 (rp2350-arm-s family). Drag onto the Pico 2 in BOOTSEL. Verified: builds clean; produces a valid 6-block UF2. Runtime (does it blink?) is the on-device check. Next: drivers (display first) + link pm-core.
