Plan 2 of the web embedding SDK: a self-contained, framework-agnostic TypeScript core wrapping the Plan-1 wasm Viewer. createViewer -> OpViewer with load, read-only snapshots (document/pages/pageCount/activePage), pan/zoom navigation (+ wheel), SVG export, load/viewportchange events, and destroy. Read-only: no .op editing/mutation. Self-contained: zero @zseven-w/pen-* deps (types vendored from jian-ops-schema ts-rs), tsup build, vitest+jsdom tests that mock the wasm seam. 10/10 tests; tsc clean; post-destroy use-after-free guarded. React+Vue adapters follow in Plan 3.
