Summary

Separates the required Microsoft MIT license header from the descriptive comments in contributions.css and contributors.css, allowing the exact-header CI check to recognize both files without changing CSS behavior.

Relates to #1608.

Demos

N/A — this is a comment-only CI fix with no user-visible behavior change.

Before

N/A.

After

N/A.

Testing

• pnpm headers:check — passed; all 964 in-scope files have the required header.
• git diff --check — passed.
• Focused website formatting/lint — no website-specific CSS formatter or lint command is defined; the existing CSS formatting is preserved exactly outside the comment boundary.

Documentation and compatibility

None. No product behavior, API/CLI compatibility, dependencies, or upgrade steps are affected.

Checklist

• If Portal features changed, keep CLI capabilities in sync. (N/A — Portal features unchanged.)
• If Portal components changed, update their Storybook stories. (N/A — Portal components unchanged.)
• If database changes require a migration, include up() / down() and keep it CosmosDB-compatible. (N/A — no database changes.)
• If dependencies changed, update the lockfile and regenerate NOTICE / NOTICE-REVIEW.txt with pnpm notice as needed. (N/A — no dependency changes.)
• Video showing the behavior before the suggested change (N/A — no user-visible behavior.)
• Video showing the behavior after the suggested change (N/A — no user-visible behavior.)

Superseded by the equivalent license-header commit now included in #1601 so the existing seven-layer stack can remain intact.
