The renderer bridge builds and keeps an effects port over a viewer no
renderer is bound to, with a factory the Cesium effects module provides,
so visual settings on a consumer's own viewer draw their styles, bloom
and sharpen as before and give the scene's bloom back when destroyed.
The application shell loads the factory; a test checks every export
that reaches the effects lookup loads it.
The effects port puts each style Core defines on its own post-process
stage, takes the scene's bloom stage and adds a sharpen stage, with the
mappings the application uses today. An animated style holds frames and
advances its time uniform while it draws. A replaced style keeps drawing
until its intensity is 0, so Core can crossfade; the contract, the stub
and a new conformance check say so. The conformance renderer has the
port; the application renderer does not yet.
