Deploy CNN Visualizer to Cloudflare Pages through GitHub Actions.

Goal

Set up a production deployment pipeline that:

• Builds the app automatically from GitHub
• Publishes dist/ to Cloudflare Pages using Wrangler
• Keeps production deploys tied to main
• Documents required secrets, variables, and verification steps

Success Criteria

• A GitHub Actions workflow builds the project on every push to main
• The workflow deploys the generated dist/ folder to Cloudflare Pages
• Required GitHub secrets and repository variables are documented
• The production site serves the app and model assets correctly from Cloudflare
• The workflow can be rerun safely without manual local deploy steps
