Research direction

Start by locating the parser's handling of the pitm box and the existing AVIF-related tests or fixtures. Trace how an av01 primary item is recognized, then establish coverage showing that a grid primary item is accepted without breaking current AVIF parsing.

Written by the indexing model from the issue text.

Description

avif compliance

While it's typically the case that the "primary item" (indicated by the pitm box) of an AVIF file is an item of type av01, that is not always the case. Alternatively, it can be an item of type grid (and possibly others).
