/**
 * Writes the fixture scene tools/e2e.mjs asserts against: two top-level crates with a collider
 * child each, a camera, the Mover behavior owning the red crate and a Spawner. Kept separate
 * from tools/seed-demo.mjs so the shipped demo can change without rewriting 100+ checks; the
 * fixture's objects are uniquely named and positioned exactly where the checks expect them.
 *
 * Usage: PATH=/opt/node22/bin:$PATH node tools/seed-e2e.mjs [projectId] [baseUrl]
 * Defaults to the dedicated fixture project; the demo project is refused.

 * "Mover" behavior in five nodes: every frame, move the owner along the normalized arrow-key
 * axis, scaled by the `speed` variable per second (On update's dt feeds the dt input).
 * Diagonals are not faster than straight moves because Axis input normalizes the vector, and
 * Move's "Collide with solids" stops the owner's solid colliders at other solid colliders.
