/// ── The handoff screen ranks by type, not by boxes ──
///
/// Every group on this screen used to be a bordered, filled, rounded rectangle:
/// a green result banner, a shadowed hero card, a bordered list card with a
/// bordered pill inside it and a filled badge inside that. Four containers and a
/// shadow, down a page holding about forty words.
///
/// The cost was not ugliness, it was ranking. A border says "this is separate
/// from its neighbours"; give that to all four groups and none of them is
/// emphasised, so the rider's eye lands on whichever box is biggest rather than
/// on the one fact he opened the screen for — where he is going next.
///
/// The redesign carries rank with type size, colour weight and whitespace, and
/// spends its one border on the single change of subject. These tests pin that,
/// because a comment asking for restraint does not survive the next redesign.
