#!/usr/bin/env bash
# Tag the current commit with the version in package.json and publish a
# matching GitHub Release whose body is the corresponding CHANGELOG.md entry.
#
# Run AFTER you have:
#   - bumped package.json
#   - added a `## [X.Y.Z] - YYYY-MM-DD` block at the top of CHANGELOG.md
#   - committed, pushed to origin, and run `npm publish`
#
# Idempotent: safe to re-run after a partial failure. Skips steps that are
# already done (tag created, tag pushed, release published).
#
# Usage: ./scripts/release.sh
