 ## Architecture Overview

-**Core Structure**: xterm.js is a multi-target terminal emulator with these main source areas:
- `src/primitives/`: Building blocks (buffer, parser, input, data, utilities); TypeScript project `src/primitives/tsconfig.json`
- `src/runtime/`: Services, `CoreTerminal`, `InputHandler`, public API adapters; TypeScript project `src/runtime/tsconfig.json`
- `src/target-browser/`: Browser terminal with DOM rendering
- `src/target-headless/`: Node terminal without DOM
-
-See `src/ARCHITECTURE.md` for the dependency graph and import-path conventions (`common/*`, `target-browser/*`, `target-headless/*`).
+**Core Structure**: xterm.js is a multi-target terminal emulator with three main distributions:
+- `src/browser/`: Full-featured browser terminal with DOM rendering
+- `src/headless/`: Server-side terminal for Node.js (no DOM)
+- `src/common/`: Shared core logic (parsing, buffer management, terminal state)

 **Key Classes**:
 - `Terminal` (browser/headless): Public API wrapper

 ## Writing unit tests

 - Unit tests live alongside the source code file of the thing it's testing with a .test.ts suffix.

-## Cursor Cloud specific instructions
-
-**Demo server**: Start with `npm start` (port 3000). The demo server uses node-pty to spawn real shell sessions over WebSocket. Integration tests auto-start it via Playwright's `webServer` config, so you don't need to start it manually for `npm run test-integration`.
-
-**Build before testing**: Always run `npm run build && npm run esbuild` before `npm run test-unit`. Integration tests also need `npm run esbuild-demo-client` and `npm run esbuild-demo-server`. The update script handles this automatically on session start.
-
-**No external services**: This project has zero external dependencies (no databases, Docker, or APIs). Everything runs locally with Node.js.
-
-**TypeScript compiler**: The project uses `tsgo` (native TypeScript compiler preview) rather than standard `tsc`. It's installed via the `@typescript/native-preview` package.
-
-**Lint only changed files**: Prefer `npm run lint-changes` over `npm run lint` when iterating on code changes — it's significantly faster.

  A constructor setting, thus you would have to anticipate, whether (multiple) terminals in your page gonna do lots of concurrent decoding. Since this is normally not the case and the memory usage is only temporarily peaking, a rather high value should work even with multiple terminals in one page.
 - `storageLimit`  
  A constructor and a runtime setting. In conjunction with `storageUsage` you can do runtime checks and adjust the limit to your needs. If you have to lower the limit below the current usage, images will be removed in FIFO order and may turn into a placeholder in the terminal's scrollback (if `showPlaceholder` is set). When adjusting keep in mind to leave enough room for memory peaking for decoding.
- `sixelSizeLimit | iipSizeLimit | kittySizeLimit`  
-  Constructor settings. This has only a small impact on peaking memory during decoding. It is meant to avoid processing of overly big or broken image sequences at an earlier phase, thus may stop the invoked decoders from entering memory intensive tasks for potentially invalid data.
