/* file-view.css — styling owned by the unified file-management component

   component. Design: docs/architecture/file-management-view.md.

   It carries only what the component INTRODUCES or what isn't guaranteed on
   every consuming page. The files-table / bulk-toolbar / state-badge /
   delete-confirm / trash-actions chrome still lives in admin-shell.css, and the
   entity-row / mod-group chrome in admin-files.css / admin-moderation.css; those
   are consolidated here as each call site migrates (docs plan, phase 5). The
