build.py - regenerate index.html for the AI Cost Watch interactive tool.
Reads costwatch.json (the frozen dataset) and writes a single self-contained,
dependency-free index.html with the data embedded verbatim. Standard library only.
Usage (run in your terminal):
python3 build.py
To add a new issue: append one object to "issues" in costwatch.json (and any new
"readings" to the indicators), then re-run this script. Nothing else changes.
