 ### Fixed
 
 - The admin build failed on a combined `import type` statement, so the Settings card never appeared.
+- Delete did nothing and the create progress modal never showed: both modals sat outside `sw-page`'s named slots, which Vue 3 drops. They now live in `#content`.
 - Creating a dump failed on MariaDB when only MySQL 8's `mysqldump` was installed (`Unknown table 'COLUMN_STATISTICS'`); it now passes `--column-statistics=0` in that case.
