/* ═══════════════════════════════════════════════════════════════════════════
   APP SHELL STYLESHEET — restructured
   ─────────────────────────────────────────────────────────────────────────
   Structure:
     01. Design tokens (colors, spacing, z-index, sizes)
     02. Base / reset / typography / scrollbars
     03. Form elements (buttons, selects, labels)
     04. App shell layout (toolbar, main content, map)
     05. Fixed utility controls (hamburger, gear, lighting, audio, sign-in…)
     06. Quick-search widget (#qs-widget)
     07. Map nav sliders (#map-nav-controls)
     08. Draw panel (#draw-panel)
     09. Floating panels (.controls, .category-filter)
     10. Reading table / status / selection UI
     11. Omniport panel
     12. Map popups & tooltips (Mapbox + custom)
     13. Modals (settings, astro, stellar, account auth)
     14. Body state classes (.table-expanded, .grid-collapsed, .ios-browser)
     15. Responsive layers
           ≥ 601px  desktop & tablet shell
           601–1024 tablet refinements
           ≤ 768px / coarse pointer  touch refinements
           ≤ 600px  phone (shared)
           ≤ 600px portrait / landscape variants
     16. Accessibility (reduced motion)

   Breakpoints (keep in sync — CSS vars can't be used in @media):
     600px  = phone | 768px = small tablet / touch | 1024px = large tablet
