"""Thin launcher for package-doks-blue.

This file is both the skill payload and the repository entry point:
blue/blue in the repository is a symlink to it. It deliberately holds no
logic of its own: validation, the graph and the steps all live in the
package-doks-blue library, where the test suite reaches them. A copied
payload is the one place in this project where code cannot be tested, so
nothing that can live elsewhere should live here. DOKS_LIB_ROOT names the
repository root; the blue implementation lives under its blue/ directory.
