Same Safari quirk as management's own .file-input (assets/management.css): the file input's Choose Files button is shadow content that ignores align-items/flex centering, so an explicit box height left it floating at the top with dead space below. Fixed the same way -- size the box from padding-block around the button's own height instead of an explicit height. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
