/**
 * Pivot table & pivot cache check.
 *
 * Each `xl/pivotTables/pivotTableN.xml` declares a `cacheId` that must be
 * registered in the workbook's `<pivotCaches>` list; the cache in turn
 * must back a live pivotCacheDefinition/pivotCacheRecords pair.
 *
 * We do a lightweight cross-reference check: (a) every pivot table
 * advertises a cacheId that resolves to a `<pivotCache>` entry in
 * workbook.xml, and (b) each referenced pivotCacheDefinition's rels point
 * at a pivotCacheRecords file that actually exists.
