Run a Tunelito live review room for a local HTML/Markdown file or folder, then process the comments it collects. Use whenever a user wants to share, serve, or preview a local .html page, .md memo, or static site/mini-site from their machine so a designer, client, teammate, or PM can leave feedback on a call; wants a temporary public link to a local page; says "review my HTML", "annotate this page", "review this Markdown draft", "let people comment on my site", "get feedback on index.html", "spin up a review room", or "review this page locally without exposing it"; OR points you at a `*.comments.md` / `site.comments.md` inbox and asks you to apply, process, or act on the comments inside it. Covers starting and sharing a session (Cloudflare Tunnel, keyed bearer URLs), local-only review of sensitive pages, active-agent `tunelito inbox` commands, the opt-in `--agent` worker that edits files from comments, and the comment Markdown schema (scope, page, path, id, status). Do NOT use for reviewing a pull request, IDE
