The supplied media was prepared on 2026-09-08. The media inventory maps each optimized asset to its original; original JPEGs and MP4s remain unchanged. See the cover inventory, video notes and media prompt catalog.
The hands-on inventory maps the supplied L01.jpeg through
L26.jpeg images to the 26 preparation guides and exercises. Their WebP covers
are downscaled without stretching. Most use a centered crop; the conditionals
and SDK application covers use side padding to preserve the complete scene.
The JPEG originals remain unchanged. Each guide retains its localized SVG in an
expandable concept view. The covers are illustrations, not product screenshots
or evidence of test results.
Required hero format:
- 1456×832 pixels for adventures; 1440×630 pixels for hands-on guides;
- PNG or WebP;
- keep essential text outside the artwork and preserve source provenance;
- meaningful alt text in the consuming page;
- retain a still image when adding video.
Motion assets must not autoplay with sound and must respect prefers-reduced-motion.
The site loads the silent teasers only after an explicit play action and offers
native controls, a still-image reset, localized descriptions and direct file links.
