Project description:
"I need a provably fair Odd/Even hash-based game built for the web. The core flow is simple: a player places a wager, a secure hash seed is revealed after the round, and the outcome (odd or even) can be independently verified for fairness.

Front-end and back-end should work together seamlessly. I’m open to modern stacks—React, Vue, or plain TypeScript on the client, with Node.js, Go, or another performant language on the server—as long as the result is fast, responsive, and easy to skin with a casino-style UI.

Key points I care about
• Provably fair logic (e.g., SHA-256 or similar) with clear verification steps shown to users
• Clean web interface that loads quickly on desktop and mobile browsers
• Secure wallet / balance handling hooks ready for later crypto or fiat integration
• Admin ability to adjust house edge, max bet, and seed rotation interval
• Lightweight analytics (total wagers, user win/loss, RTP) exposed via an admin API

Deliverables
1. Source code for both client and server, neatly documented
2. Deployed demo on a test server showing wagers, result reveal, and verification link
3. Brief README explaining build steps, environment variables, and how the seed logic works
4. Post-handover support for initial deployment questions (up to one week)

If you’ve built Dice, Crash, or similar hash games before, that experience will translate well here. Please share a link or repo snippet that demonstrates your provably fair implementation style when you bid." (client-provided description)
