/*  Mail Processor — design system
    A cohesive dark interface optimised for ops dashboards. Inter for type,
    a 60-color scale built around three accents (blue / violet / teal),
    glassmorphism cards on a subtle gradient field, and motion-safe
    transitions for the few things that actually move (sidebar, toasts).
