// 1. Seeded Math.random: an unseeded world builds a different island on every
//    reload, so views captured across reloads would not show the same world.
// 2. window.__wb: Three.js announces every Scene and WebGLRenderer it creates
//    to window.__THREE_DEVTOOLS__ (the devtools-extension hook). Listening
//    there gives us scene/renderer/camera without editing the model's code.
// 3. window.__WB_TIME: ?wb_tod=<0..1>&wb_season=<0..3> from the URL. The
//    daytime preview (preview.py) patches the world's own clock to read this.
