Tests for #88, before the change: the format chosen for each Accept header (AVIF-capable, WebP-only, neither, wildcard only, absent, q=0 on AVIF, malformed), both image routes serving an auto URL in the chosen format with Vary: Accept, also on HEAD and 304, the signature covering auto rather than the chosen format, each chosen format cached apart, and Vary: Accept next to the CORS middleware's Vary: Origin. They do not compile yet: FormatAuto and formatForAccept do not exist. Model: opus-5-5
