Closing in favor of #4478. 8.5.10 only addresses GHSA-qx2v-qp2m-jg93; the high advisories GHSA-6g55-p6wh-862q, GHSA-r28c-9q8g-f849 and GHSA-fxqj-rqcc-2cmp require 8.5.12 / 8.5.18 / 8.5.23. #4478 bumps postcss to 8.5.31 instead.

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.

Supersedes #3572, #3552 and #3519.

- **postcss** 8.5.3 → 8.5.31. #3572 stopped at 8.5.10, which only fixes
GHSA-qx2v-qp2m-jg93; the high arbitrary file read (GHSA-6g55-p6wh-862q),
path traversal (GHSA-r28c-9q8g-f849) and the incomplete fix
(GHSA-fxqj-rqcc-2cmp) require 8.5.12 / 8.5.18 / 8.5.23. 8.5.31 is the
current 8.x release.
- **follow-redirects** 1.15.9 → 1.16.1. #3552 targeted 1.16.0, which
fixes GHSA-r4q5-vmmm-2653 but introduces two high advisories fixed only
in 1.16.1 (CVE-2026-111755, CVE-2026-111756).
- **shell-quote** 1.8.2 → 1.12.0 for the `react-dev-utils` path. #4418
updated launch-editor's copy to 1.12.0 but left the `react-dev-utils`
copy at 1.8.2; this consolidates both ranges on 1.12.0
(GHSA-w7jw-789q-3m8p, GHSA-395f-4hp3-45gv).
- **lodash** 4.17.23 → 4.18.1. #3519 has an April-era head that no
longer works with the current Build Check workflow (the job checks out
the PR head and now expects `scripts/i18n/check-configuration.cjs`).
4.18.1 fixes GHSA-r5fr-rjxr-66jc (high, `_.template` code injection) and
GHSA-f23m-r3pf-42rh (medium, prototype pollution via
`_.unset`/`_.omit`).
- **nanoid** 3.3.8 → 3.3.20, required by postcss 8.5.31.

The change is lockfile-only; `package.json` is unchanged.

Validation:
- `yarn install --frozen-lockfile --ignore-scripts` passes on top of
current master.
- `yarn audit` reports no advisories for postcss, follow-redirects,
shell-quote, lodash or nanoid.
- Only `yarn.lock` is changed.
