# Cut a release of both SDKs — dograh-sdk (PyPI) and @dograh/sdk (npm) —
# at the given version. Regenerates typed files from node_specs first so
# a stale SDK can't ship.
#
# Usage:
#   ./scripts/release_sdks.sh 0.1.2
#
# Prerequisites (one-time setup):
#   - `build` + `twine` installed: `pip install --upgrade build twine`
#   - `npm login` completed as a member of the `dograh` npm org. npm
#     publish will prompt interactively for a 2FA OTP — run this script
#     in a terminal where you can type the code.
#
# The script is idempotent up to the upload steps: each publish is gated
# by a y/N prompt, so you can dry-run the build and bail before anything
# hits a registry.
