/* Purpose:
Global RBO Field Intel design tokens, typography, controls, layout primitives, and shared responsive behavior.

Responsibilities:
- Apply the layout, responsive behavior, and visual states required by app.

Boundaries:
CSS controls presentation only; trust meaning, workflow state, privacy, and persistence remain in maintained source logic.

Key decisions and invariants:
Global tokens and primitives remain centralized so feature styles do not silently create conflicting product semantics.
