# Asterism Relay

An explorable first-person cosmos for the Build Small Hackathon's Thousand Token Wood track.

This first vertical slice proves the core loop:

- custom Three.js frontend served from `gr.Server`
- HYG-style real star sample for the background field
- one deterministic procedural body seeded from position
- backend sector JSON generated ahead of arrival
- fact layer selected from a curated local astrophysics knowledge base
- fiction layer authored separately as a vanished-civilization transmission

The production model is intentionally behind a small adapter so the author model can be selected after the planned bake-off.
