 * used to fall through to. Authorization is not a review: there is nothing to
 * revise, "Reject" is the wrong word for declining to link your own account,
 * and only one person in the company can answer at all. So the card composes
 * one title, one body, and exactly the affordances the reader legitimately has:
 *
 * - the addressed person gets the single primary **Connect <Provider>** target
 *   plus a plain **Not now**;
 * - anybody else gets **Waiting for <Person>** and no action at all — a
 *   policy-forbidden action is omitted, never rendered disabled, and the card
 *   must not imply a teammate can consent on their behalf;
 * - once resolved it states the outcome, who resolved it, and when.
 *
 * The primary action is a link to the server-minted authorization URL, not an
 * accept call: the OAuth callback is what resolves this interaction, so the
 * card never claims success the provider has not granted.
