Move 30+ loose files at src/ root into domain directories: - scene-graph/ — SceneGraph class, instances, hit-test, copy, snap, undo - color/ — parse/format, color management, OkHCL - text/ — text editor, style runs, direction, fonts - vector/ — vector network encode/decode, bezier math - figma-api/ — FigmaAPI class, FigmaNodeProxy - icons/ — Iconify API client, icon rendering - canvas/ — SkiaRenderer (was renderer/) - design-jsx/ — JSX-to-design renderer (was render/) Also: - Move fig-compress.ts into io/formats/fig/compress.ts - Delete re-export shims (headless-render.ts, svg-export/) - Convert all self-referencing @open-pencil/core/* imports to relative - Clean up package.json exports (26 subpaths, no internal leaks) - Update AGENTS.md subpath table Fixes #179
