Frontend (React + TypeScript) — placeholder

Phase 0 task "React + TypeScript frontend scaffolding" (Dev 2) and all later viewer/editor UI lives here. Not implemented yet — this session scaffolds the C++ build pipeline only.

Planned responsibilities (see the engine blueprint §9):

• Layered viewer: canvas layer, selection layer, annotation layer, overlay layer.
• PDF <-> canvas <-> zoomed coordinate mapping.
• Virtualized page rendering (only visible pages).
• Talks to the gateway over HTTP; later, to the engine directly via WASM.

Setup when implemented: Vite + React + TypeScript strict mode from day one.
