C3D-INSP2403E · Hero VP framing + candidate layers v2 (read-only) done

Parcel centroids vs each sheet's viewport view-center/height + hero-layer entity counts. Entity ambiguity fixed.

C# payload

// READ-ONLY: what does each hero viewport FRAME, and what's drawn there?
// For 09, 10, R4: the model-space view center+height each VP shows (so I know which parcel it frames),
// and the parcel centroids so I can tell which parcel each sheet is aimed at.
// Also: enumerate hero-candidate layers (SS-BOUNDARY_*) and count entities on each + which are visible.
