🧪 Demo	projects/demo	A playground app showing streaming, code, tables, math, Mermaid, i18n, caret.

Develop

npm install

# run the demo playground (http://localhost:4200)
npm start            # = ng serve demo

# build the library → dist/streamdown-angular
npm run build        # = ng build ngx-streamdown

# run the library unit tests (Vitest)
npm test             # = ng test ngx-streamdown --watch=false

If npm start / npm test aren't defined, use the explicit forms: ng serve demo, ng build ngx-streamdown, ng test ngx-streamdown --watch=false.
