Move alternate root PlatformIO file under docs/legacy and document single-entrypoint policy for release/CI. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Legacy PlatformIO Multi-target Snapshot
platformio.multi-target.ini was moved out of the repository root on 2026-03-10.
Rationale:
- keep
platformio.inias the single release entrypoint - avoid ambiguous root configs during firmware build/review
- preserve the old multi-target configuration for reference only
Policy:
- release and CI must target
platformio.ini(freenove_esp32s3_full_with_ui) - do not reintroduce alternate root
platformio*.inifiles
