/*
Purpose: style the governed scenario selector and dynamic scenario summary for the Causal Lattice Observatory.
Governance scope: accessible radiogroup controls, responsive layout, focus visibility, and scenario-reset explanation.
Dependencies: how-it-works/index.html, causal-lattice-runtime.js, and shared Mullusi design variables.
Invariants: scenario controls remain usable on keyboard and mobile, never cover the visualization,
and do not imply live execution.
