/* ============================================================
   DynaWorks — Navbar + right panel
   Breakpoint matches the site's existing mobile breakpoint
   (see mobile.css: @media (max-width: 768px)) — desktop starts
   at 769px so the old mobile menu and this new burger/panel
   never overlap or leave a gap.

   Design tokens (colors, fonts, panel width) live in dw-tokens.css —
   load that BEFORE this file.

   NOTE: .dw-nav reuses the existing .site-header for layout
   (fixed position, height, background blur, scrolled shadow,
   z-index) — it is not redefined here to avoid fighting that
   rule. Only the new .dw-nav__* / .dw-panel / .dw-backdrop
   pieces are new.
