## What & why

<!-- What does this PR change, and why? Link any related issue: "Closes #123". -->

## How it was tested

<!--
  `npm run verify` output is the baseline. If the change touches a page, say what
  you looked at and at what width; if it touches the container, say whether you
  built and ran the image.

## Checklist

- [ ] I have read [CONTRIBUTING.md](CONTRIBUTING.md).
- [ ] `npm run verify` passes locally (all eleven checks and both test suites).
- [ ] No fact is stated in prose — versions and platform facts come from `src/data/platform.json`.
- [ ] `PLAN.md` still describes what this repository does; a decision it records is either
      unchanged or amended here, with the reasoning.
- [ ] My commits are reasonably scoped, with Conventional Commit messages.
