/**
 * Outcome of a {@link ChannelVerifier#verify} probe. Designed so the
 * onboarding wizard's Step 2 can render success and failure with no extra
 * round-trips:
 * <ul>
 *   <li>{@code headline} — one-line status shown in the verify card</li>
 *   <li>{@code identity} — account display fields piped into Step 3 ("Connected as ...")</li>
 *   <li>{@code invalidField} — when failed, the form key Step 1 should highlight on "Fix it"</li>
 *   <li>{@code hint} — actionable next step, surfaced under the failure headline</li>
 * </ul>
 * The {@code skipped} variant lets channel types with no verifier (web,
 * webchat, webhook) fast-forward through Step 2 without showing an error.
