Features:
- Edit forms for Style Directions and Training Types (working)
- Delete functions with confirmation dialogs
- Responsive layout: mobile (stacked), tablet/desktop (side-by-side)

- Full CRUD except create (can use old catalogs page for now)
Mobile UX:

- Back button → return to tree
- Safe bottom padding for navigation
Desktop UX:
- 400px tree + fluid detail panel
- Both always visible
- No back button (not needed)
