/**
 * Where a model's information came from, shown on cards and in the detail header.
 * Matched on Civitai is the normal case and looks as before; only the exceptions are
 * marked: base model inferred from the file ("推断"), a damaged file, not scanned yet, and set to
 * "don't scan" (metadata.scan_choice). The detail header also names the fields the user set
 * (metadata.user_fields, from <model>.anomalous.json), and for a model not scanned whose header
 * looks like no drawing model, or one set to "don't scan", a button to change that. Its links
 * open the source link (named after its site) and Civitai's page; a model Civitai does not know
 * gets a note under it saying what was read from the file.
