-Chromium is installed from the Alpine edge/community repository using:
-<br/>
-<code>apk add chromium --update-cache --repository http://nl.alpinelinux.org/alpine/edge/community</code>
-<br/>
-This enables HTML-to-PDF conversion but triggers Twistlock/Prisma Cloud security alerts due to packages pulled from the edge repository.
+<th style="font-size:14px" width="100px">Reason

+<th style="font-size:14px">Using the Alpine Edge repository introduces packages that are not part of the stable release, which can trigger Twist lock security issues. To maintain security compliance, we should install Chromium from the stable repository.

-The <b>edge</b> repository is rolling/testing and can introduce newer dependencies and CVEs flagged by enterprise scanners. Using edge also reduces build reproducibility across environments.

-Install Chromium from the <b>stable Alpine repositories</b> (main/community) and include required runtime dependencies. This avoids the edge repo entirely and reduces security findings.

-<b>Notes</b>:
-- No edge repository is referenced; Chromium comes from stable Alpine repos.
-- Typical Chromium paths on Alpine:
-  - <code>/usr/bin/chromium-browser</code> (symlink) or
-  - <code>/usr/lib/chromium/chromium</code>
-  Set this path in your converter settings:
