Both files now delegate to web/index.php and emit an E_USER_DEPRECATED
notice. A defined() guard prevents the notice from firing twice when
Symfony Runtime re-executes the entry script via SCRIPT_FILENAME.
The deprecated wrappers set APP_ENV/APP_DEBUG to match their legacy
environments (prod/0 and dev/1) so existing web server configurations
that point to these files keep working until wallabag 3.0 removes them.
Debug::enable() is no longer called explicitly — SymfonyRuntime handles
it when APP_DEBUG is truthy.
