Dependabot triage: unsupported-major.

• Evidence: Security / audit failed at npm audit --audit-level=high (run). The recorded run reports high-severity nanoid and brace-expansion advisories. Revalidation against the current advisory DB gives nanoid <3.3.18 (GHSA-2v37-7h3g-55p8) with No fix available. The compatible chain is vitest -> vite -> postcss@8.5.x -> nanoid@^3.3.17; PostCSS 8.5.26 still declares nanoid: ^3.3.17, the registry's newest 3.x is 3.3.17, and nanoid@6.0.1 is outside that constraint. brace-expansion can move to 5.0.9, but the nanoid gate remains unsatisfied.
• Action: defer and close this bump. No major override, --legacy-peer-deps, or check bypass will be used.
• Unblock condition: recreate/reopen after either a compatible nanoid >=3.3.18 is published or PostCSS/Vite moves to a safe nanoid line, and Security / audit passes.

[dependabot]

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. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

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