The Pages workflow now builds the game (npm ci && vite build in spaceship/) and publishes it at /spaceship/ alongside the existing site. Deploying straight from this branch was attempted but the repo's github-pages environment protection only allows deployments from main, so the merge is what flips it live (the root site at ehpurple.com is untouched).

What this is

A small first-person demo (spaceship/) where you walk the interior of a used-future, Star Wars-style ship in flight. Built with Vite + three (r184), fully procedural — no downloaded models or textures. Developed in an autonomous build → screenshot → judge → fix loop until every rubric item passed on two consecutive iterations (iterations 8 and 9 of a max 12).

Highlights

• Modules: player.js (pointer lock, WASD, head bob, capsule-vs-AABB collision), ship.js (kit-bashed cockpit/corridor/quarters/galley/bathroom, merged static geometry), space.js (parallax starfield, shader planets with atmosphere rims, nebulae), interact.js (raycast hover + prompts + fades + rest-cycle lighting), post.js (N8AO, bloom, ACES, vignette/grain), textures.js (canvas-generated PBR maps), main.js.
• Interactions: bed (fade, "8 hours pass", lighting shifts to rest cycle), galley ("Energy restored"), bathroom sink (fade, "Refreshed"), one-line HUD status with ship clock.
• Self-evaluation harness: tools/shots.mjs spawns vite + headless Chromium (SwiftShader), drives window.debugAPI.setView(...) for deterministic cockpit / corridor / quarters / window captures, plus scripted interaction smoke tests; full per-iteration scoring lives in spaceship/PROGRESS.md with screenshots in spaceship/shots/.
• Key bug found via the loop: N8AO was gamma-correcting inside the composer while OutputPass converted to sRGB again — the whole frame was double-gamma'd; every shot before iteration 4 was washed out. A/B probe captures isolated it.
• Budget: ≤239 draw calls / ~122k tris worst view, 3 shadow maps (1×1024, 2×512) — comfortably 60 fps-class on a mid-range laptop GPU.

The four final views
