Turns the site into a small multi-view app. Three pinned nav buttons above
the search (App Center pin style) switch the main pane:
- How it works: the former footer text, expanded into cards (add an app,
point your box here, how trust works, run your own).
- Submit an app: the PR-based flow (fork → drop-in app folder → PR → reviewed
+ signed → published with a community badge + your name). No uploads/accounts.
- Submissions: renders a static submissions.json (operator-published, like the
catalog) — author names, status badges (pending/review/merged), PR links,
a pending-count badge on the pin, graceful empty/loading states.
Category/search return to browse; #<slug> deep-link still focuses one app.
REPO_URL is overridable via <meta name=lp-repo>.
