+ * Bundle required web fonts during Docker image builds and serve them from LinkLog
+ * New Entry page warns when the title/URL combination already exists, matching the browser extension's duplicate warning
  * New Entry page warns when an existing link with the same title has a different or missing URL (after tracking parameters are stripped)
  * New Entry page auto-fills the title when the URL field loses focus, instead of requiring a manual button press
  * Added a "Re-fetch Title" button to manually re-scrape the title after editing the URL
  * New Entry duplicate detection and submission strip known tracking parameters (utm_*, gclid, fbclid, etc.) from URLs, mirroring the browser extension
-
+ * Browser extension popup now matches the New Entry page: it warns on duplicate title/URL, notes when the stored link has a different URL, and gained a "Re-fetch title" button; bumped extension version to 0.2.0
 
  ### Fixed
  * Fixed element ID conflict on the Admin page so Available Themes load correctly

 ### Assistant outcome
 Appended the new-entry duplicate-detection and title auto-fill work to `VIBE/PROMPTS.md` and `VIBE/CHAT_LOG.md`, and added a Version v0.1.3 section to `CHANGELOG.MD`.
+
+### User
+Make sure the webplugin has the same functionality as just implemented in the new-entry page. Increase its version number to 0.2.0.
+
+### Assistant outcome
+Brought `webextension/popup.js` to parity with `new-entry.js`: the duplicate check now distinguishes an exact title/URL match from a title match with a differing stored URL (using the same `/api/links/check` `url_matches`/`stored_url` fields) and shows an additional localized note in the latter case; added a "Re-fetch title" button that calls the backend `/api/scrape` endpoint (guarded by existing backend-permission checks) and auto-fills the title on URL blur when empty; reworked `setStatus` to render real `<br>` line breaks via DOM APIs instead of `textContent`. Added `duplicateLinkDifferentUrl`, `refetchTitle`, and `titleFetchFailed` strings to all five locale files, updated `popup.html` with the new button, and bumped `manifest.json` to version `0.2.0`. Full backend test suite (36 tests) passed.

 240. I want this last change to be more precise: I do not want to be warned when parameters are stripped, but when the URL entered has arguments/parameters and the URL in the database has none or different ones (even after tracking parameters are stripped).
 241. In the check duplicate I have a `<br>` tag, but that shows as formatted text on the page, I want a real break to occur at that position.
