// TK-12097 Batch D (Gaston Y Daniela) — merge the two hi-res sources into the final
// apply-hires swap map. Mirrors build-batchA-final.mjs (READ + copy pattern).
//   source 1: data/tk12097/batchD-swap-map.json      (gaston_daniela_catalog Brandfolder, width=2048, MEASURED)
//   source 2: data/tk12097/batchD-phase2-results.json (kravet.com Brandfolder hero, MEASURED long_edge)
// For each low-res product (<=500px), pick the LARGER genuine upgrade (> current AND >= 800 floor).
// Colorway safety: staging join is colorway-exact (always safe). A phase-2 kravet.com hero is trusted
// ONLY when its filename contains the product's SKU code; filename-color-matches-but-pattern-base-differs
// rows -> HELD to batchD-tier2-colorway-unverified.json, NEVER put in the map.
