 * GOVERNANCE GUARDRAIL (ADR-011)
 * =============================================================================
 * 
 * Design System Scope:
 * - Visual consistency ONLY
 * - NO shared authority, logic, or data
 * - Trust boundaries enforced by ADR-011
 * 
 * This file provides TOKENS and PRIMITIVES for visual consistency.
 * It does NOT provide shared state, JS logic, or permission checks.
 * 
 * The three dashboards remain architecturally separate:
 * - /dashboard/compliance  → Tenant-scoped (Customer view)
 * - /dashboard/governance  → Platform-wide (Operator view)
 * - /dashboard/executive   → Aggregated (Board view)
 * 
 * Liability banners are trust-boundary indicators.
 * They MUST NOT be themed, hidden, or restyled.
 * See ADR-011: Dashboard Trust Boundaries
