+## ${TAG_NAME} Release Notes
+
+<!--
+Maintainer guide (please read before publishing; this HTML comment is
+invisible in the rendered Release page):
+
+1. This file is the skeleton for the draft Release body. It is rendered
+   by the `release` job in .github/workflows/release.yml using Python's
+   string.Template.safe_substitute.
+2. Placeholders that get substituted automatically at render time:
+     TAG_NAME              current tag, e.g. vX.Y.Z
+     VERSION               version without the leading `v`, e.g. X.Y.Z
+     FULL_CHANGELOG_URL    compare URL against the previous tag
+   Note: these three names must appear as `$` followed by braces in the
+   template body to be substituted; this comment intentionally spells
+   them without that syntax so it does not substitute itself.
+3. HTML comments under each section are classification hints. Delete or
+   keep them before publishing (kept comments stay invisible to readers
+   and save effort on the next release).
+4. If a section has no content for this release, delete it entirely or
+   write "None".
+5. Classification follows conventional-commit PR title prefixes:
+     feat(scope):         -> ✨ Features
+     fix(scope):          -> 🐛 Bug Fixes
+     refactor(scope):     -> ♻️ Refactoring
+     docs(scope):         -> 📚 Documentation
+     chore/ci/build/test: -> 🔧 CI & Chore
+6. Highlights is the "elevator pitch" — pick 1-3 changes users should
+   care about most (new capabilities, breaking changes, or fixes with
+   wide impact).
+7. For pre-release versions (tag contains a/b/rc/post), tick
+   "Set as a pre-release" on the draft page so this release does not
+   occupy the /releases/latest endpoint.
