Electron consumes launch paths from its baked stamp, not a fixed
Python-version directory. Backups preserve data and declarations,
not runtime downloads or browser profiles.
State both contracts in the build and migration guides. Keep the
backup exclusions and quick/full distinction aligned across English
and Chinese, with stable comparison anchors.
The bilingual site build, website typecheck, pinned diagram linter
and added-prose checks passed. All six affected routes and new
backup links were checked in rendered output. Unrelated locale-link
warnings remain. No native package acceptance is implied.
