Stage 0. Zero-dependency serve.py (static + allowlisted horizons/sbdb/cad proxy, sha256 disk cache with past-span immutability). Three.js via pinned importmap, logarithmic depth, procedural starfield sky (+ Milky Way panorama swap-in), Sun with additive glow, OrbitControls, brass-and-void HUD, scrubbable time bar, central bodyWorld position pass, focus/camera system, hash state. Boots clean, no console errors. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
