Viewer: native geometry and derived display

Native points and display pose — Measure original native points, apply a separate display pose and select a projected point in the actual 3D view.

Viewer loads bounded native CAD inputs and displays sampled Surface/Curve geometry through the public GPU backend. Use it when your host needs a canvas, camera controls, qualified object references and explicit query boundaries.

Checkpoint: 5f5ad866205a; version 0.0.0-experimental. Public configuration is local source availability, not verified npm publication. Use ordinary package-name imports with the existing TypeScript-capable workspace host and Node 22+. No source condition is required. Plain Node cannot resolve internal source .js specifiers to .ts.

Four separate results

The original native model retains coefficients, weights, knots and IDs. Sampling creates display packets. Caller-authored poses transform display without editing that model. GPU rendering creates pixels. A display pick is approximate; a native parameter query evaluates the original geometry at stated parameters.

Caller ownership includes canvas/DOM, input focus, transport/cancellation, source revisions, simulation clock and disposal. Viewer owns its accepted copied state and GPU presentation resources.
