 [Image delivery CSV](readiness/image-delivery.csv) records actual rendered widths, DPR, selected `currentSrc`, source widths, start/end times, response format and bytes for all 12 foreground cases. [Interaction detail](readiness/interaction-detail.json) retains image loading/priority, full srcsets, first/repeat font/image resources, headers and viewer requests. Source photography remains San Francisco 1600×900/123,410 B, architecture 1200×675/65,890 B and canyon 1600×900/155,072 B. The unchanged 7,557 B integration SVG remains vector-served. Source width/height and frame aspect ratio reserve space before decode. Critical hero media is preloaded; other media is lazy and viewer originals mount only on demand. The 13 srcset candidates are unique; 384px is no longer duplicated across device/image size lists.
 
-Final Chromium repeat visits report `deliveryType=cache` and zero transfer for the cached images and font. The hash-based optimizer URLs return WebP, ETag, `Vary: Accept` and immutable caching; font URLs are content-hashed and immutable too. [Optimizer MISS/HIT/304 evidence](readiness/optimizer-cache.json) is explicitly from intermediate `179c340`, whose image pipeline is unchanged in `66faa48`. This is browser/local-optimizer evidence, not proof of Vercel edge behavior or CDN transformation latency. No image service was added.

[Optimizer MISS/HIT/304 evidence](readiness/optimizer-cache.json) is explicitly from intermediate `179c340`, whose measured 384px transformation, source assets and quality settings are unchanged in `66faa48`; the final image-size configuration additionally removes the duplicate 384px candidate.
