Overview

Resolves the file types a picker field accepts and matches content types against them, so the same rule drives the browser's native , the greying-out of non-matching library assets, and the server-side upload check. A token may be:

- an exact mime type   ("image/png")
- a type wildcard      ("image/*")
- a file extension     (".png")

Extensions are mapped to a mime type via Marcel so server-side matching stays consistent with what the browser lets a user pick from disk.

This is a plain value object (not Active Record); it lives under app/models only so Zeitwerk autoloads it alongside the engine's other domain types.
