  "prompt": "Create two additional public demonstrations in this same project; do not change website/index.html. (1) game/index.html: a polished, self-contained vanilla HTML/CSS/JS 4x4 memory-pairs game called ORBIT PAIRS, with eight pairs of space-themed symbols, move counter, elapsed timer, matched count, win message, restart, keyboard-operable cards, and reduced-motion support. No packages, downloads, external assets, network calls, storage, credits or deployment. (2) A controlled bug-repair exercise, not a real production incident: preserve bugfix/before.js exactly as: export function totalCents(items) { return items.reduce((sum, item) => sum + Math.round(item.price * 100), 0); } . The defect is that it ignores quantity. Create bugfix/after.js correcting quantity; reject non-integer or negative quantities and negative or non-finite prices; quantity zero is allowed; empty cart totals zero. Provide bugfix/index.html showing the before/after code and a working demo of totals. Provide a README.md inside each folder with limitations and an honest account of checks. Only write these files. Do not launch browsers or execute commands; I will perform independent tests. End when files are written.",
