PR #73 Deployment Analysis

PR #73 updates actions/checkout@v5 to v6 in .github/workflows/webpack.yml. GitHub Actions builds succeed, but Cloudflare Pages deployment fails.

Root cause: The failure is unrelated to the actions/checkout upgrade. GitHub Actions and Cloudflare Pages are independent systems - the checkout action only affects GitHub's CI environment, not Cloudflare's deployment pipeline.

Likely issues:

• Cloudflare Pages build configuration (commands, output directory, Node/pnpm versions)
• Environment differences between GitHub Actions and Cloudflare build environments
• Missing environment variables in Cloudflare

Cloudflare dashboard logs are required to identify the actual deployment error.
