Module card 

Component group — one collapsible section per component on the entity.

Deliberately flat: a chevron, an icon, a name, a category tag, and a hairline. It used to be a bordered, filled card per component, which turned a five-component entity into boxes inside boxes inside a panel — the structure stopped being readable exactly when there was enough of it to need reading. Hierarchy now comes from type and spacing.

The row actions (enable toggle, remove) appear on hover. They are rare and destructive-adjacent; the resting state should read as data, not as a toolbar.

Constants

Functions

category_for 🔒

The domain a component belongs to, shown as a small right-aligned tag.
