Reduce grouped mark-gone refresh to summary fetch only

 - grouped result is a better template for “new item from existing definition”
 - not expanding children keeps the query lighter
 
+### List pagination
+
+- `GET /{database}/kitchen/items` and `GET /{database}/kitchen/items/grouped` are paginated (`limit`/`offset`, backend default `limit=100`)
+- frontend API helpers aggregate pages when no explicit `limit`/`offset` is requested
+
 ### Grouped stock view
 
 Grouped stock view uses:
 
-- `GET /{database}/kitchen/items/grouped?expanded=1`
+- `GET /{database}/kitchen/items/grouped?expanded=0` for summary
+- `GET /{database}/kitchen/items/grouped?expanded=1` for hydrated child details
 
 Important:
 
 - group-level fields are meaningful and should be used
 - group expiration status should follow the backend-provided “first item expires” semantics
-- do not assume grouped child records are always returned unless `expanded=1`
+- with `expanded=0`, grouped child `items` may be ID-only stubs (`{ id }`)
+- do not assume grouped child records are fully returned unless `expanded=1`
+
+### Stock updates
+
+- `POST /{database}/kitchen/items/{uuid_b64}/stock` creates a stock event and returns `{ status, stock }`
+- frontend refreshes item details with `GET /{database}/kitchen/items/{uuid_b64}` after stock updates
