Local revalidation on 2cdcd8b:

• node --input-type=module ... sanity check -> exactly one Zed entry with the expected contributor URL, avatar id, and tags
• gh api repos/zed-industries/zed --jq ... -> public, unarchived, enabled, default branch main
• gh api -X GET repos/zed-industries/zed/issues -f labels=.contrib/good\ first\ issue -f state=open -f per_page=1 --jq length -> returned 1 open issue
• curl -L -s -o /dev/null -w "%{http_code}" https://github.com/zed-industries/zed/contribute -> 200
• curl -L -s -o /dev/null -w "%{http_code}" https://avatars.githubusercontent.com/u/79345384?v=4 -> 200
• pnpm install --frozen-lockfile -> passed
• GITHUB_TOKEN=$(gh auth token) pnpm build -> passed, 2 pages built
• generated dist/index.html contains the Zed card and https://github.com/zed-industries/zed/contribute
• git diff --check origin/main...HEAD and git diff --check -> clean

Closing this to reduce maintainer review noise from my project-suggestion-only PR batch. I am pruning these so the queue can focus on concrete bug, security, accessibility, and performance fixes.
