Each limb was one straight uniform tube — a peg poking out of a pole, and the
most visible art problem in docs/yard_day.jpg. They now leave the trunk thick,
sweep up on a bezier and taper to nothing, which is what a gum does. +96 tris on
gum_01, silhouette bounds unchanged.
Nothing physical moved. The tip is a bezier endpoint and the four rng draws per
branch are the same four in the same order, so every branch_anchor_* is
bit-for-bit where it was — verified before and after, all five identical to 6dp.
Lane A's winning line rigs off t2 and is untouched; no balance number can shift.
e.test.js now hard-codes those five world positions as a tripwire, so no future
art change of mine can quietly invalidate a sprint of someone else's physics. If
it goes red, the art moved an anchor — fix the art, not the numbers.
Card text and the dawn-tint treatment go to Lane A in THREADS. The tint is a CSS
snippet rather than a ninth texture: only two of my eight are consumed, and a
full-screen gradient needs no asset at all.
Selftest 262/0/0, 38/38 output files byte-identical.
