+- Quarto TinyTeX installation path has been updated from `/root/.TinyTeX` to `/opt/.TinyTeX` to fix potential permission 
+  issues when called from a non-root user. As a result, Quarto will no longer recognize TinyTeX as a managed 
+  installation. This change is not expected to affect the existing functionality of Quarto or TinyTeX for end users.
+  TinyTeX's relevant packages will still be linked to `/usr/local/bin` as before.
