- Split pane: card layout with border, border-radius, box-shadow
matching mock's bordered panel look
- List pane: bg-surface background, padded header with border-bottom
- Entity items: border-bottom separators instead of gap spacing,
flex-start alignment for multi-line content
- Detail pane: bg-surface background, 20px padding, right border-radius
- User meta line: show email + group path (like mock's "email · group")
- Create form: raised background with bottom border
