/**
 * Placeholder game: top-down "collect the coins" demo. Exercises every
 * subsystem (Pixi rendering, Rapier physics, Howler audio, tween bobbing,
 * input, scene transitions) so the developer has a working reference for
 * each.
 *
 * REPLACE the gameplay specifics — coins, scoring, win condition — with
 * your own game logic. The frame loop and resize wiring are the parts to
 * keep.
