 * Built-in rule factories. Each takes a constraint and an optional `message`; when omitted, the
 * rule falls back to a localized default from `FileValidationLocalization` (kit ships no English
 * literals — defaults follow `AppLocale`). The `Mime` factory additionally attaches `.accept` so
 * containing UI cmps (`FileUploader`, `OpenFileButton`) can auto-derive the native picker filter /
 * drag-over hint.
 *
 * @example
 * ```ts
 * const rules = [
 *   FileRules.Mime('image/*'),
 *   FileRules.MaxSize(5 * 1024 * 1024, 'Image must be under 5 MB.')
 * ];
 * const results = await FileValidator.validateMany(files, rules);
 * ```
