Exporting BROWSER=omarchy-launch-browser into the whole uwsm session made xdg-settings refuse "set default-web-browser", which broke every browser's own "Set as default" button. The export only exists for terminal programs (like gh) to open URLs detached from the terminal process tree, so move it to default/bash/envs where interactive shells still pick it up.
