Summary by cubic

Bumped dev dependency postcss from 8.5.16 to 8.5.23 to pick up security hardening around source map loading and minor bug fixes. No production code changes.

Description

  • Summary of changes
    • Updated postcss to 8.5.23 in lockfile.
    • Transitive bump of nanoid to 3.3.16.
  • Reasoning
    • PostCSS now restricts loading previous source maps without opts.from and confines map loading to the opts.from folder for security.
    • Includes small parser fixes (e.g., semicolons around comments, at-rule spacing).
  • Additional context
    • If our PostCSS pipeline relies on implicit source maps, ensure from is set in PostCSS options. Avoid unsafeMap: true unless necessary.

Docs

  • Add a note in /docs/ build/tooling section to reflect postcss@8.5.23 and the stricter source map behavior (set from in PostCSS config if source maps are used).

Testing

  • No tests changed.
  • Validate: npm ci && npm run build passes; CSS outputs unchanged; source maps (if produced) still generate correctly with from set.

Semantic version impact

  • Patch. Dev-only dependency update with no API or runtime changes for consumers.

Written for commit d3df6f3. Summary will update on new commits.
