// FRONTIER (deferred 2026-06-03): one `captured` block updating MULTIPLE cells =
// store territory (the new model is single-cell). Old brace form. NOTE: still green
// coincidentally — the new transform ignores brace-form captured, so this survives;
// it is slated for store rework. See project_capture_dissolves_into_effect_cell.
// Test: Single `captured` block updates multiple captures simultaneously
// This demonstrates that captures create a combined state space where
// field names must be unique, and `captured { a: X, b: Y }` updates
// ALL captures that own those fields.
