Drop the work-in-progress banner
The geometry has been in the operator since the flux-form
Laplace-Beltrami scheme landed, so the banner's claim -- that other
shapes show the sphere's pattern painted onto them -- has been false
for a while. Removes it along with the .warn rule and the six --warn-*
variables, which nothing else used.
Two neighbours said the same stale thing and go with it: the geometry
picker's tooltip ("Rendered, but not yet in the operator") and the
per-surface note in the page ("Rendered only"). The intro also called
the shape compiled, which it no longer is.
