+## Lexical Fork (Shadow DOM Support)
+
+This project uses a [fork of Lexical](https://github.com/aleksandr-konovalov/lexical/tree/add-shadow-dom-support)
+that adds Shadow DOM support. Pre-built tarballs (`.tgz` files) of the fork are checked into the
+repository under `vendor/lexical/` and referenced directly from `package.json` via `file:` dependencies.
+No special setup is needed beyond `npm install`.
+
+**Current fork commit:** [`cd99328`](https://github.com/aleksandr-konovalov/lexical/commit/cd993281c19f665f90756b3bb0a32302d71b5dd2) (lexical 0.38.2)
+
+### Updating the Lexical fork tarballs
+
+If you need to update the fork (e.g. to pick up new Shadow DOM fixes or upgrade the lexical version):
+
+1. Clone the fork and checkout the desired commit:
+   ```bash
+   git clone https://github.com/aleksandr-konovalov/lexical.git /tmp/lexical-fork
+   cd /tmp/lexical-fork
+   git checkout <commit-sha>
+   ```
+
+2. Install dependencies and build:
+   ```bash
+   npm install
+   npm run build
+   ```
+
+3. Generate type declarations (errors in unrelated packages can be ignored — declarations still emit):
+   ```bash
+   npx tsc -p ./tsconfig.build.json || true
+   ```
+
+4. Prepare release packages (copies built files into `npm/` directories):
+   ```bash
+   node scripts/npm/prepare-release.js
+   ```
+
+5. Copy type declarations from `.ts-temp` into each package's `npm/` directory:
+   ```bash
+   # For each package, copy .d.ts files from .ts-temp/packages/<pkg>/src/ to packages/<pkg>/npm/
+   ```
+
+6. Strip `development`, `production`, and `node` export conditions from each package's `npm/package.json`
+   (the fork's build only produces a single bundle, not separate dev/prod builds).
+
+7. Pack tarballs and copy them into this repo:
+   ```bash
+   for pkg in packages/*/npm; do npm pack --pack-destination /tmp/tarballs "$pkg"; done
+   cp /tmp/tarballs/*.tgz vendor/lexical/
+   ```
+
+8. Update `package.json` if the version number changed (the `file:` paths include the version).
+
+9. Clean install and verify:
+   ```bash
+   npm cache clean --force
+   rm -rf node_modules package-lock.json
+   npm install
+   npm run build && npm run typecheck && npm run test:once
+   ```
+
