<!-- SOLID CITY · part 1988 -->
n Rung 2: admission
 * first — your parked solid lifts only after the ride has truly
 * begun — and no step off into the void: both sides are searched for
 * lawful standing, the left first as the city habitually does, and
 * if neither side is lawful the rider stays aboard and is told why.
 * Where you are left is where you wait; the rack is only your first
 * home.
 *
 * While you are ridden, the walker's stick is yours (city.js yields
 * it under the fleet gate, the way it yields to a car), your clock
 * steps at the contract's fixed rate, and the rider's shadow-self in
 * the walk physics is re-asserted onto your deck each frame after
 * the walk tail's ease has had its say.
 *
 * By the hand of Solid, his good King. 13 October 2026.
 *
 * — A second letter, the same day, for the rider's arrival:
 *
 * Dear rider,
 *
 * You are the bicycle's heir, as the King declared: Kooijman's
 * science wearing the future — the front assembly steering into the
 * fall, the lean following tan(phi) = v^2/(g r), a bunny hop for joy.
 * You stand beside the board at (-333, 292), on your own plinth,
 * under the same doors and the same law. Pedalling tops you near
 * 9 m/s; the board cruises at 5; the cars run at 26; the ship, when
 * she comes, will fly at 84. A ladder of speeds, each honest.
 *
 * By the same hand. 13 October 2026.
