The error renderStill rejects with when the toolpath geometry build fails (instead of never
settling). Same shape as the parser's ParseSessionError, so a still job handles a parse failure and a
build failure the same way: branch on code, show message.

message — the renderer's description of what failed.
The internal renderer is already disposed when this rejection arrives.
