/*
Purpose: professional Pilot route presentation for qualification, readiness, and access boundaries.
Governance scope: operational readability, responsive controls, and shared Mullusi shell alignment.
Dependencies: pilot/index.html and assets/styles.css.
Invariants: access remains visibly closed, state meaning is not color-only, and canonical readiness terms remain unchanged.
