Alt+W held the sky dome solid so the edges had something to read
against. Looking at it, the dome was the problem: lit, fogged and
filling the upper half, it washed out everything behind the near
geometry. A whole structure over the track in the middle distance was
invisible until the sky came away.
So the view now clears to BLACK under wireframe and the sky pass is
skipped entirely. Skipping costs nothing - the dome only ever covers
pixels the clear already owns - and it removes the two fill-mode
brackets that used to wrap the pass, so the frame is simpler than it
was. Both changes are conditional on gWireframe; the solid path clears
to the fog colour and draws its sky exactly as before.
Fog still applies to the edges, which is why the middle distance tints
toward the fog colour instead of staying bright. That is depth
information, so it stays.
environ.ini's template and BUILD.md both said the sky stayed solid.
