+"""MVP dashboard router — read-only aggregations for the warehouse +
+procurement dashboard widgets consumed by the frontend `apiV26.dashboard`
+client (frontend/src/lib/api.ts).
+
+Scope (same resolution pattern as the inventory / pm routers):
+- role 'pm' → limited to the projects they manage (projects.pm_user_id, 1:N);
+  an explicit ?project_id must be one of them.
+- role 'admin' / 'procurement_manager' → whole organization; ?project_id is
+  an optional filter.
+- Dev fallback via X-User-Role / X-Project-Id headers, ONLY when
+  PROCUREMENT_DEV_LOGIN_ENABLED=true (read-only endpoints, same gate as the
+  inventory router).
+
+Endpoints:
+- GET /dashboard/filters                    — «What» cascade options
+- GET /dashboard/inventory/drilldown        — org → project → warehouse tree
+- GET /dashboard/inventory/dead-stock       — dormant stock table
+- GET /dashboard/inventory/flow             — daily inbound/outbound/returns/balance
+- GET /dashboard/daily-control              — today's tickets + performers
+- GET /dashboard/procurement/workload       — workload per project (density)
+
+Every response is the standard `{"data": …}` envelope.
