/*
This stylesheet defines the responsive operator dashboard presentation.
It owns visual layout, typography, and health/quality states only.
It must not encode business rules or depend on collector/database implementation details.
AI CONTEXT:
- Keep quality colors consistent across cards, badges, rows, and warnings.
- Preserve readable contrast in both dark and light system color schemes.
- Avoid framework-specific class conventions; this UI intentionally has no npm build step.
