Reviewing the two new files: docs/footer.tsx and docs/styles.css additions.

Security: No issues. The link uses rel="noopener noreferrer" correctly. No secrets, no injection vectors, no unsafe patterns. Clean.

QA findings (2 issues, 1 suggestion):

ISSUE 1 -- Footer is not wired up and will not render.
The Footer component is created in docs/footer.tsx but is never imported or referenced in vocs.config.tsx or any layout file. Vocs does not auto-discover components from docs/. As-is, this PR adds dead code -- the footer will not appear on any page.

Two options to fix:
(a) Use vocs built-in outlineFooter config (renders in the sidebar outline area):
In vocs.config.tsx, add: outlineFooter:

Then import Footer from "./docs/footer"
(b) Use a custom layout override if you need the footer at the bottom of the content area (requires a docs/_layout.tsx or similar approach per vocs docs).

ISSUE 2 -- Missing trailing newline in docs/styles.css.
The appended .footer block ends without a newline character. This triggers git/editor warnings and is inconsistent with the rest of the file (which ends with a newline). Add a blank line after the closing brace.

SUGGESTION -- Copyright year may be outdated.
The footer says "© 2023". Consider using "© 2023-present" or "© 2023-2026" to keep it current without annual updates. Match whatever convention the LICENSE file uses.
