A regular neighborhood carrying the actual sharp projection estimate

theorem OAI.RegularPointCoordinates.exists_regular_sharp_neighborhood line 21
Source documentation
All sources and coordinates are constructed from the cited inputs. The positive source has any requested square budget and controls the actual normalized two-center projection at every admissible center and scale.
