The new package internal/imagerequest holds the request type, its two parts Source and Transform, the Format and Fit types, the dimension and fit checks, the /v1/image/ path parsing and the variant key; it imports no other package of pixa. imgcache.ParsedURL, imgcache.ImageRequest, signature.Request, imageprocessor.Request, the second Size, format and fit types and the conversions between them are gone. The image processor takes a Transform only. encurl keeps a private struct with the token's short CBOR field names. VariantKey moves with the function that makes it. Tests follow the moved and renamed code; the tests of the removed conversions go with them. Model: opus-5-5
