Visitors can switch between the station and full-body sunflower scene using small image-only thumbnails, then browse and compare all 77 styles. Each scene keeps independent English style and composition prompts, bilingual titles and technique tags, and the correct benchmark caption.

Integrate the approved station prompt/image replacements and all 77 youth samples (75 new outputs and two verified existing outputs). Preserve exact frozen generation text, original sample histories and checksums, and visible observations about faint colors or palette/detail deviations.

Validation:

• Build and all 50 Node tests passed in both the working tree and an archive of the committed tree.
• Verified 308 detail views, 942 clipboard actions, 48 filter/search/sort/keyboard checks, and both languages at 320/390/820/1487px.
• Confirmed all 215 changed files on the remote branch, with no credential-scan findings and a clean working tree.

This PR merges the reviewed source changes. No separate production deployment is included.
