Finite first surface.
Non-Euclidean / Riemannian / fold geometry.
Euclidean underneath: routes, sections, DOM, headings, metadata, export. Folded on top: seams, chambers, anchor continuity, intent pacing, temporal return.
Controlled transition.
Deeper content room.
Adaptive proof path.
Resolved action state.
The math stays internal. The visitor feels it as depth, orientation, pacing, and return.
