PR Explainer

Create a local, self-contained HTML page that teaches a reviewer the PR story: what changed, why it matters, how it works, how it fits into the system, and how it was verified.

Required workflow

1. Understand the PR before writing HTML
   • Collect PR title/number, branch, link if available, base branch, commit range, changed files, and verification already performed.
   • Inspect the current state with git status --short.
   • Inspect recent commits with git log --oneline -n 10.
   • Inspect scope with git diff <base>...HEAD --stat and git diff <base>...HEAD.
   • If one commit carries the main change, inspect it with git show --stat <commit> and git show <commit>.
