How do I curve the collect flight toward the screen edge or center?

bezierFly(..., { lean: 'up' | 'down' | 'in' | 'out', curvature }) bends the arc; around sets the in/out reference point. Those helpers are demo code in apps/site/src/runtime/holdAndWinFx.ts, not exports of the pixi-reels package -- copy them into your project.
