 **Rule:** No feature modules in v1. Flat `composeApp/commonMain` with the package layout above.
 
+**Rule:** A `screens/` package is a *stateful* UI feature (screen + ViewModel), not necessarily a nav route. `recipedetail` presents as a modal bottom sheet and is opened from multiple hosts (search, later planner) — it lives under `screens/` because it owns a ViewModel, while its leaf widgets (`IngredientRow`, `NutritionSummary`) stay in `components/`, which is reserved for stateless, VM-free composables.
+
 ## Non-negotiable conventions
 
 1. **Sync timestamps come from the server, never the device.** `updated_at` is assigned server-side; pulling uses lexicographic `(updated_at, id)` cursor.
