+- Small stac changes
+  - This PR includes some changes that were suggested in a review for #297. But because the PR was already merged I'm including them here:
+    - removes extra block to include in docker compose files (no longer needed)
+    - moves docker compose file in `stac-public-access` component to the correct location
+    - uses `PAVICS_FQDN_PUBLIC` for public facing URLs in all places
