Dims, tri counts and node names all pass on a bike leaning the wrong way and
a gutter that never fell. The Blender contact sheet is close but renders
through Blender's view transform — it showed this sprint's jacaranda as
near-white lavender when the material is #8C7FC0, so a colour call made there
is a call about Blender, not about the game.
Smallest thing that answers the question: the game's own vendored three.js,
daylight, a ground plane, and the 1.7 m ref capsule beside whatever you name.

It caught two things this sprint the numbers could not: the lilac reads lilac
in the real renderer (the thumb was lying), and the swing set's wreck lands on
+Z with a 2.9 m reach against a 0.95 m standing footprint — which is now baked
as a placement extra and asserted.
Sized at draw time, every time: a tab that boots hidden reports 0x0 and you
get a correct scene rendered into nothing. That cost me the first screenshot
of this very page, so it is in the MANUAL gotcha list where it already was.
