/*
 * ApprovalGate
 *
 * Drawn in Figma as `Approval Gate` (1160:423), Risk × Status. Structure is
 * Alert's — icon rail, body, one variable per colour slot — which is why
 * drawing it needed values checked here rather than a rewrite. The action row
 * borrows Button's ramp.
 *
 * RISK CHANGES EMPHASIS, NOT MEANING
 *
 * Three risk tiers reassign four variables, exactly the way Alert's intents do.
 * `low` sits on the neutral surface, `medium` on information, `high` on
 * warning — NOT on error. Error is for something that has gone wrong; a
 * high-risk approval is working correctly, and it is asking. Reserving red for
 * failure is what keeps red meaningful when a failure actually happens.
