/**
 * card-fields.ts, recognising a payment field on any page.
 *
 * Lives in security/ rather than in payments/ or browser/ because both need it
 * and neither owns it. The browser's snapshot must suppress a payment field's
 * value whether or not the payment capability is even configured, and the
 * payment capability must classify the same way the snapshot does or the two
 * disagree about what was protected. A shared rule in the layer they both
 * already depend on is the only arrangement where that cannot drift.
 *
 * It is also why `platform/browser/` still imports no product surface: this is
 * foundation, like link validation and the public-suffix list beside it.
 *
 * ── Why this is a classification and not a lookup ─────────────────────────
 *
 * There is no registry of merchants here and there must never be one. A rule
 * written against the standard `autocomplete` tokens works on every checkout
 * that wants browser autofill to function, which is every checkout that works
 * at all; the name and id patterns catch the rest. Neither needs to know which
 * site it is looking at.
 *
 * ── Erring toward yes ─────────────────────────────────────────────────────
 *
 * A false positive costs the model the contents of one form field, which it can
 * ask the owner about. A false negative hands it a card number. Those are not
 * comparable, so the patterns are broad and the tie goes to suppression.
 */
/**
 * Everything about one control the classification may look at.
 *
 * A plain record rather than a DOM element, because the function that walks a
 * page is serialized and evaluated inside the browser and can import nothing.
 * The in-page collector gathers these attributes; the judgement happens in
 * process, where it can be tested against real inputs instead of merely read.
