+# Quick release script - builds Linux + macOS locally and uploads to GitHub.
+# Linux is built inside an Ubuntu 22.04 container for an older glibc baseline.
+# macOS is cross-compiled via osxcross (~/.osxcross). Windows is built by CI.
+#
+# Setup (one-time):
+#   1. Install osxcross at ~/.osxcross
+#   2. rustup target add aarch64-apple-darwin
+#   3. Add to ~/.cargo/config.toml:
+#        [target.aarch64-apple-darwin]
+#        linker = "aarch64-apple-darwin23.5-clang"
+#
+# Usage:
+#   scripts/quick-release.sh v0.5.5              # tag + build + release
+#   scripts/quick-release.sh v0.5.5 "Fix bug"    # with custom title
+#   scripts/quick-release.sh --dry-run v0.5.5    # build only, don't publish
