+//! Combinatorial cost-parity tests between v1 (`build().estimate_cost()`) and v2
+//! (`build2().estimate_cost()`) for the Fal-hosted Seedance video models.
+//!
+//! The goal: every request that produces a price in v1 must produce the
+//! identical price in v2. If any callsite picks a different price after the
+//! port, billing diverges. These tests close that gap.
+//!
+//! Both pipelines ultimately delegate to the same `FalRequestCostCalculator`
+//! impls in `fal_client`, so parity should hold by construction — but we
+//! exercise a wide variety of inputs anyway to catch any drift in the request
+//! plumbing (e.g. resolution/duration mapping errors, default-value mismatches,
+//! aspect-ratio fallthroughs).
