//! Per-item failure parity with the wasm path (alignment audit).
//!
//! `processGeometryBatch` always used the submesh path, where an unsupported
//! representation item is skipped and the rest of the element still renders.
//! The server's default path used single-mesh `process_element`, whose item
//! loop bails with `?` — one exotic item made the WHOLE element invisible in
//! server/parquet output while the browser showed it partially. This pins the
//! server-side skip behaviour.
