/* Global Security Operations App — shell styles.
   Design tokens (colors, radius, shadows, buttons, cards, tables, forms) are extracted verbatim

   branded "Global Security Operations," so its design language is this app's design system,
   per the Migration & Architecture Plan §6. Structure/pattern (nav, login, admin panels, toasts,
   modals) follows Haltitude Aviation's app.js conventions, rebuilt for this app's own components. */
