- Return the ResourceNotFoundError detail from get_civitai_versions and
get_model_versions_status instead of a bare "Model not found", and let
the download modal display the server-provided message
- Anchor extract_civitai_image_id / extractCivitaiImageId to
^/images/<id> so API paths and partial numeric IDs are rejected, same
as the model-page parsing fix in #1140
- New OptimizationMode.DISPLAY (width=2400 for images, full quality for
videos) and getDisplayUrl(); the in-modal main viewer renders at most
~1200 CSS px wide, so full-size originals wasted 50-70% bandwidth
- Main viewer and adjacent prefetch use display URLs; the full-size
media viewer keeps using getShowcaseUrl for original quality
- Warm the HTTP cache for examples adjacent to the active one after
expand and on every navigation, so prev/next feels instant (images
only, deduped, low fetch priority)
- Add GALLERY_THUMBNAIL optimization mode (width=160) for the 72px
gallery strip instead of reusing the 450px card thumbnails
- Hint priorities: fetchpriority=high on the main media, low on
strip thumbnails
- Update CSP whitelist to use wildcard *.civitai.com for all CDN subdomains
- Fix hostname parsing to use parsed.hostname instead of parsed.netloc (handles ports)
- Update rewrite_preview_url() to support all CivitAI CDN subdomains
- Update rewriteCivitaiUrl() frontend function to support subdomains
- Add comprehensive tests for edge cases (ports, subdomains, invalid URLs)
- Add security note explaining wildcard CSP design decision
Fixes CSP blocking of images from image-b2.civitai.com and other CDN subdomains
- Add CivitAI URL utility with optimization strategies for showcase and thumbnail modes
- Replace /original=true with /optimized=true for showcase videos to reduce bandwidth
- Remove redundant crossorigin and referrerpolicy attributes from video elements
- Use media type detection to apply appropriate optimization (image vs video)
- Integrate URL optimization into showcase rendering for improved loading times
