/**
 * Generic per-cell three-way-merge helpers, shared across every kind
 * whose baseline payload is a flat `Record<path, hash>` map.
 *
 * Two halves:
 *
 *  1. {@link classifyCellHashMaps} — given desired / current / baseline
 *     hash maps, produce a per-path {@link FieldClassification}. Paths
 *     present in only one side classify against the absent-value hash
 *     (`hashJsonValue(undefined)`) on the other.
 *
 *  2. {@link resolveCellByPolicy} — given a classification + a push
 *     policy, decide whether the desired or current value wins for a
 *     single cell. Returns `"policyError"` when the policy is `"error"`
 *     and the classification is one that can't be silently merged
 *     (`cms-edit` / `conflict`).
 *
 * Each domain's merge driver still owns its recipe-shape traversal —
 * brands have sections × fields, campaigns have project + deliverables
 * × tasks — but the dispatch logic ("which side wins this path?") is
 * identical and lives here.
