+/**
+ * Extract a release-notes block from CHANGELOG.md for a given version
+ * (or unwrap text supplied on stdin), then join hard-wrapped paragraphs.
+ *
+ * Why: GitHub renders release-note Markdown with GFM hard breaks, so
+ * every `\n` becomes `<br>`. The CHANGELOG is hard-wrapped at ~75
+ * chars for readable diffs, which then renders as awkward visible
+ * line breaks on the release page. This script joins indented
+ * continuation lines into a single line per bullet so the GFM
+ * renderer produces clean paragraphs.
+ *
+ * Repo-level CHANGELOG.md viewing is unaffected (CommonMark treats
+ * newlines as spaces there).
+ *
+ * Usage:
+ *   extract-release-notes.mjs <version>     # read CHANGELOG.md
+ *   extract-release-notes.mjs --stdin       # read from stdin (any text)
+ */
