Tree view
Folders and hierarchies: the media library tree and the vision-check failure reasons (module → checkpoint → category) with their toggles.
Covers: M15. Exports: Tree.
Anatomy
The component as it sits in the product: English, compact, real data shapes.
States
5 states, left to right, top to bottom. A mock poll never finishes, so each state is drawn on purpose.
No folders yet
Upload into the library root, or create a folder.
Density
The phone shell is always comfortable (POWERUPS #15): 44px tap targets, 16px inputs. Compact exists on desktop only; see the desktop page.
English · 中文

Long string · permission denied
The long-string case (PL-063) and what a role without the permission sees (the server decides; T003).
