"""Shared snippet virtual Start-node identifiers and compatibility helpers.

injects one at runtime. Existing workflow references commonly use the public

selector shape ``#start.<var>#``; keep that contract stable by treating the

runtime-only snippet Start node as compatible with the legacy ``start`` id.
