Add automated preview and production deployment workflow for the frontend #297
Description
Summary
The repository has hosting configuration for Vercel and Netlify, but the GitHub workflow set currently covers CI and secret scanning only. There is no repository-level automation documented for preview deployments, production promotion, or deployment verification.
Why this matters
Hackathon judges and collaborators benefit from predictable preview URLs and automated production promotion from the main branch. That also reduces release friction and makes the project feel more mature.
Proposed work
- Add a deployment workflow for preview builds on pull requests and production deploys from main.
- Include smoke checks or deployment verification after the build is live.
- Document required secrets, environment variables, and rollback steps.
- Surface preview URLs in PR workflows where possible.
Acceptance criteria
- Pull requests can trigger preview deployments.
- Merges to main can trigger or pr- Merges to main can trigger or pr- Merges to main can trigger or pr- Merges to main can triggere- Merges igured.
- The deployment process is documented end to end.
