Notes: Two WebFetch reads of each page with differently worded prompts (A: transcribe then map; B: per-field questions); only values both reads returned identically are recorded. Read A: Matches scout expectation (Polished Gold / Black Polarized / 50-21). No fit wording in title/meta; temple length, lens height, UV, lens material, GTIN not stated. Read B: Matches scout expectation (Polished Gold / Black Polarized / 50-21). Same clock reading as the other fetches (read once before the parallel batch).
