Firebase Demo Deployment Assistance

I have a front-end codebase (JS, HTML, JSON, Markdown, Yarn lock files) that needs to live on Firebase, but first I want to walk through it in a real browser. You will help me spin up a fresh Firebase project, wire up Hosting, and deploy the site to an online preview channel so I can review every screen before we push anything to production.

What you’ll actually do:
• Initialise or configure the Firebase project from scratch, including CLI setup.
• Add or adjust firebase.json, .firebaserc and any build scripts so the site compiles and serves correctly.
• Deploy to a preview URL (Firebase Hosting “channel” or equivalent) and share the link so I can inspect the visuals.
• Once I sign off, promote the same build to the live channel.
• Hand over concise notes on how I can repeat the workflow for future updates.

Acceptance criteria
1. Preview link loads the full site without console errors.
2. Visual layout matches my local files.
3. Production deploy uses the exact approved build.

If this fits your skill set with Firebase Hosting, CLI, and vanilla JS tooling, let’s get started—I’m ready to share the repository right away.
