Fix the Deadlike later.

[Stolas]

Found one dead link in the landing page:

Dead Link:

• "Security Details" button links to #security anchor which doesn't exist in README.md

Suggested Fix:
Either:

1. Add a ## Security section to README.md, or
2. Update link to point to line 15 where security is mentioned: #L15, or
3. Remove the anchor and link to repo root

The main "View Documentation" link works correctly.
