The October 7, 2026 iPhone Duo press kit is the strongest page in the sample: it has a named author, publication and modification dates, BlogPosting schema, a product-update label, and specific folded, unfolded, and crease-aware layout descriptions. The publishing system around it needs a repeatable gate. The crawl finds duplicate host variants, an offsite canonical, repeated title and meta descriptions, one missing alt attribute on each sampled variant, and a privacy page with no meta description, no viewport, and 980px scroll width at 390px. Add checks for canonical host, metadata, viewport, overflow, alt text, heading structure, paragraph boundaries, and claim evidence before adding pages.
