feat: AI Death Clock GitHub Page

[Copilot]

Adds a static GitHub Pages site visualising the environmental cost of global AI token consumption — live counters, environmental milestone tracker, growth chart with projections, and a prompt/PR quality scorecard.

Core files

• death-clock-core.js — all pure logic (token formatting, impact calculations, milestone detection, date predictions, scoring). No DOM deps; fully unit-testable.
• script.js — DOM layer: requestAnimationFrame counter loop, Chart.js init, milestone/table/scoring rendering, theme toggle.
• styles.css — CSS-variable theming (dark default / light), scanline overlay, glow/blink/pulse animations, responsive grid.

Features

• Live counters — cumulative global total (~65 Quadrillion, ticking at 100M tokens/sec), per-session counter, and rate display
• Environmental milestones — 7 thresholds from 1T → 100Q tokens, each with triggered badge, consequence text, "following event", and progress bar:
  🌲 Trees → 🐝 Bees → 💧 Water → 🪸 Coral → 🧊 Glaciers → 🌊 Ocean → 💀 Extinction
• Chart — historical data + 18-month log-scale projection via Chart.js CDN
• Predictions table — calendar date + relative time for each upcoming milestone
• Dark ↔ Light mode toggle
• Prompt/PR scoring — collapsible rubric, 74 → 94/100 after addressing recommendations

Tests & CI

• 75 Jest unit tests · 96% line coverage on death-clock-core.js
• .github/workflows/test.yml — runs on every push/PR
• .github/workflows/deploy.yml — deploys to GitHub Pages on push to main

⚠️ Post-merge setup required

GitHub Pages source must be set to GitHub Actions once under Settings → Pages → Source. The deploy workflow is already committed.

Original prompt

Build a github page that shows a death clock. Correlate x tokens consumed to the removal of something like a tree, and y tokens consumed for the removal of bees, and z tokens consumed for the removal or another life essential. Show what would be the event that follows for each of those token consumed thresholds. Also graph tokens used over time and predict what day we will have consumed x, y, z and other milestones. Make it cool. Allow it use either dark mode or light mode via a button. Say it was created by RB. Let me know if this needs to reconfigured after deployment. Unit test it all. Score this prompt and pr out of 100, show recommendations and score impact, then address each recommendation
