# Public demonstration downloads

Only existing permitted marketing examples and local derivatives are included. No customer files, authenticated URLs, live account data, new provider output, or processing requests are used.

- `original-headphones.jpg` and `optimized-headphones.jpg`: previously published JPEG examples, both 1024 × 1024; 190,732 and 120,213 bytes. The rounded 37% saving applies only to this sample.
- `catalogcut-optimizer-sample.zip`: the one saved optimized headphones JPEG and an explanatory README. Not a new completed optimizer batch.
- `catalogcut-cutout-samples.zip`: two local PNG encodings of the existing public bag/headphone Cutout previews, with an explanatory README. Not the original 1600 × 1600 worker exports.
- `sample-cutout-{500,1000}.{png,jpg,webp}`: fixed square local encodings of `/landing-live/bag-cutout.webp`, prepared offline with Sharp. PNG/WebP preserve transparent padding; JPG is flattened onto white. These are not files from the interactive destination/quality plan, and do not demonstrate the production worker's encoding or exact pixel output.
- `north-studio-logo.png`: authored sample logo for a fictional brand, not a customer endorsement.

Public derivatives are cropped/resized/re-encoded; Cutout removes the background and local sample encodings add padding or a white backdrop. No endorsement is implied. Ceramic vase source: **Joostik**, [Bay 66 14, Wikimedia Commons](https://commons.wikimedia.org/wiki/File:Bay_66_14.jpg), CC0. Beauty and headphone concept sources were created for CatalogCut demonstration use; headphones were created with Google AI. These origins were traced to the retained 2026-09-21 source-license receipt.

Apparel licenses and provenance are documented in `/landing-apparel/README.md`. Original source dimensions are not inferred from public derivatives; public encoding dimensions, format, alpha and byte counts were independently checked. Other reused ring previews remain previously permitted examples. The private QA acceptance archives stay private.

Historical ring files under `/marketing-stage/` have `.png` names but contain JPEG preview encodings. Do not treat their extension as evidence of original Stage delivery format. Current Stage native-output capability and these historical public preview encodings are separate.

Real output-proof gaps remain for hand/arm isolation, edge refinement, AI backgrounds, local Preserve revision sequences and model continuity. Corresponding demonstrations are explicitly local illustrations or controls previews, not invented worker results.
