Task 10: Add "How this was made" section to README disclosing AI
collaboration and project costs. Landing page updated separately.
Task 11: Calibrate energy-per-token against Google (Patterson et al.,
Aug 2025) and "How Hungry is AI" (Jegham et al., May 2025). Previous
values (0.003/0.015 Wh per 1K tokens) were ~10-100x too low. Updated
to 0.05-0.3/0.25-1.5 Wh per 1K tokens with model-dependent ranges.
Worked example now produces ~246 Wh, consistent with headline figures.
CC0-licensed methodology for estimating the environmental and social
costs of AI conversations (20+ categories), plus a reusable toolkit
for automated impact tracking in Claude Code sessions.
