/**
 * Presentation 2 and loose-Presentation-3 input, translated to the shape the
 * parser reads.
 *
 * Vocabulary only. `on` becomes `target`, `full` becomes `source`, `oa:` types
 * lose their prefix, and a bare string target carrying a media fragment becomes
 * an explicit SpecificResource and FragmentSelector — the parser reads a
 * selector and treats a string target as an opaque IRI, which is correct of it
 * and leaves splitting the fragment to the consumer that knows a Canvas is
 * being addressed.
 *
 * No selector *value* is interpreted here. That is the parser's codec, and
 * Mango holding a second opinion about `xywh=` is what this migration removed.
 *
 * This lives beside the canonical adapter rather than in the IIIF resolver
 * because every route into the model needs it: a manifest, an annotation page,
 * a host calling `addAnnotation` with a plain object, and a repository reading
 * back what it stored.
 */
/**
 * Rewrites a Presentation 2 annotation into the Presentation 3 shape.
 *
 * Only the envelope: `on` becomes `target`, `resource` becomes `body`, and
 * `cnt:chars` becomes `value`. Everything inside — selector values, SVG,
 * fragments, legacy `oa:`/`sc:` motivations, 1×1 point regions — is the
 * parser's to interpret, and Mango reading any of it a second time is how the
 * two interpretations diverged in the first place.
