<!--
  File: micro-apps/text-tools/url-formatter-cleaner-with-titles-v2.html
  Purpose: Extract only regular (non-image) HTTP/HTTPS links from large pasted text,
           and (optionally) fetch page titles to emit Markdown links WITHOUT bullets
           and WITHOUT any leading "Title:" prefixes.

  Notes:
    - Single-file Micro-App (no build step, no local assets).
    - In-line comments explain each section in plain language.
    - Title fetching is best-effort: many sites block cross-origin reads (CORS).
      • We first try a normal fetch.
      • If that fails and the "Use proxy" option is ON, we fall back to https://r.jina.ai/<URL>
        which returns a readability-friendly text version that often contains the page title.
      • We sanitize titles to strip "Title:" and leading headings/bullets.
      • If everything fails, we fall back to the URL's hostname as the title.
