isokit: web Studio (engine as WASM, projects in the browser or a live folder)
- isokit-wasm: wasm-bindgen build of the engine; a project in memory behind the same JSON API as `isokit studio`, plus the MCP tools - isokit-project: Store trait (FsStore folder, MemStore memory) under a generic Workspace; Project::from_files; shared Studio API module (api.rs) used by serve.rs and the WASM build; web_time for clocks in the browser - studio.js runs on a pluggable backend (window.IsoKitBackend); no Studio keys while a dialog is open - web/: projects in IndexedDB, new/demo/delete, zip export/import (stored and deflated), folder import by drop or picker, folders opened live via File System Access with outside edits followed, code editor, page build and preview, two tabs in step, isokit.mcp() and WebMCP registration - tools/build_web.py -> dist/web (static), tools/check_web.py (44 checks)
