/**
 * Mission Control CSS
 * Styles for the unified control plane dashboard.
 *
 * Phase 3.1-3.2 (backend-unification-execution plan):
 * The --mc-* color tokens are now thin aliases over the canonical
 * theme-tokens.css palette so Mission Control inherits any global
 * theme update (light/dark) without diverging. Hard-coded fallback
 * values preserve the historical "Tokyo Night" admin look on pages
 * that load mission-control.css before theme-tokens.css.
 *
 * Layout-only and accent tokens (sidebar width, ribbon height, the
 * Tokyo Night accent colors) stay namespaced because they are
 * MC-specific.
