The browser examples and SDK used JavaScript and a Vite application. This change converts their sources, tests, and Node tooling to TypeScript, and rebuilds all eight examples with Next.js App Router, React, shadcn/ui, and Tailwind CSS. Elixir/Phoenix continues to handle accounts, permissions, persistence, and WebSockets.

The React application manages accounts, rooms, presence, and connection cleanup. Existing collaborative editor and canvas bindings mount inside React hosts, preserving shared undo, offline edits, permissions, and live cursors. Existing .html example URLs remain supported.

The SDK ships compiled ESM with generated declarations. Next.js exports static pages into the Phoenix release, so production requires no Node server. CI, Docker packaging, development proxying, and documentation are updated accordingly.

Validation completed locally:

• TypeScript checks for the SDK, examples, tests, and tools.
• 59 Playwright browser tests, 58 Elixir tests, 8 SDK tests, 14 model tests, and 7 standalone operations tests.
• Packed SDK imports, shared Yjs identity, NodeNext/bundler type resolution, and a Vite consumer build.
• Next.js production build and ARM64 Docker release build.
• HTTPS staging rehearsal covering all eight exported examples, collaboration, permissions, offline reconnect, release replacement, database outage recovery, and backup restoration.
• Isolated TypeScript load run with 4 clients across 2 rooms, including a 1.1 MB transfer, reconnect, persisted replay, and connection cleanup.
