world.js sways a tree by rotating a `canopy` group whose origin sits at the
trunk top, so the blobs swing about the trunk. The trees shipped canopy_01..03
as siblings of `trunk` with each origin at its own blob centre — rotating one
spins a sphere in place, which is visually nothing. Lane A could not have swayed
these trees, and the canopy lean is the gust telegraph the player reads a beat
before it hits the sail, so the tell would have gone missing rather than looked
wrong.
Adds the `canopy` empty at the trunk top with the blobs parented under it, so
A's existing code works unchanged, plus sway_amp / sway_phase / sway_pivot_y
for the per-tree tuning SPRINT2 §Lane E asks for (gum_01 is big and leans less
at 0.85; gum_02 is whippy at 1.20 and shows a gust first).
sway_phase draws from its own RNG stream: taking it from the shared one would
consume a value and shift every blob draw after it, resilhouetting a tree the
other lanes have already tuned against. Exported dims are identical to Sprint 1.
e.test.js asserts the pivot by rotating the handle and measuring that a blob
actually travels — red before this change, green after.

Replaces the skip stub with the checks Lane A's header asked for — every GLB
loads, is metre-scale with height on +Y, and keeps the nodes other lanes query
by name — plus anchor world-position and the garden bed's three damage states.
This catches what the Blender side structurally cannot: Blender exports
Z-up->Y-up and imports Y-up->Z-up, so a broken export_yup round-trips green.
A native glTF reader is the only thing that can prove the file.
GLTFLoader is imported dynamically on purpose. Three.js addons import the bare
specifier `three`, no page in the repo has an importmap yet, and selftest.html
turns an un-importable lane module into a hard FAIL — so a static import would
redden Lane A's merge gate over a harness gap rather than a real defect. It
skips with the fix instead, and lights up by itself once the importmap lands.
Verified behind a temporary probe first: 36/36 pass. Need logged in THREADS.

selftest.html only imports; each lane owns js/tests/<letter>.test.js. Five lanes
sharing one selftest.html would be the single guaranteed merge conflict in the
repo, so the stubs are pre-created with each lane's PLAN3D asserts written into
the header.
No rAF anywhere: it's throttled in a hidden tab, so a rAF-driven selftest would
pass only while you watch it. fixedLoop() drives time instead.
Lane A's suite covers the §5-A acceptance criteria, including "camera never
clips through house" — stated as the underlying invariant (no solid between the
player's head and the camera) so it survives Lane E swapping the house GLB.
