/* =======================================================================================
   Dekhing — Enterprise Shell & Design System (Phase 1)
   Additive layer on top of style.css. Reuses the existing slate/green palette and
   Fira Sans/Code typography. Introduces:
     • an 8px design-token scale (spacing, radius, elevation, motion, type)
     • a collapsible left sidebar + top navbar (desktop/tablet ≥1024px)
     • a mobile navigation drawer (<1024px)
     • the redesigned hub → device Dashboard

   Nothing here changes app behaviour: navigation is driven by shell.js clicking the
   existing hub buttons, so every workflow/socket/Firestore call fires exactly as before.
