// FT-P-53 (DatasetItem.isSplit honored).
//
// Per the task spec, only FT-P-51 and FT-P-53 are `fast + e2e`. The other
// rows (FT-P-52 parser, FT-P-54 auto-zoom, FT-P-55 indicator, FT-N-10
// malformed) are fast-only. Both e2e tests are `test.fail()` today
// because the split surface is QUARANTINED in production (per
// `_docs/04_refactoring/01-testability-refactoring/deferred_to_refactor.md`
// row D11 and the traceability matrix's `[Q]` marker on AC-39).
//
// Once the SPA wires a "Split tile" affordance and starts honoring
// `DatasetItem.isSplit`, remove the `test.fail` and these flip green.
