/* ============================================================
   NEONBET · Mobile shell — top bar + bottom tab bar + left drawer
   (frontend-redesign-v2 · faithful port of the designer package)
   ------------------------------------------------------------
   Ported verbatim-in-spirit from neonbet-design-ref (components.css
   + base.css), re-expressed on tokens.css. Renders the designer's
   .topnav / .bottombar / .mobile-drawer. js/nav.js injects the markup
   and wires every control to EXISTING production flows (auth modal,
   office panel, deposit, setLang, balance APIs) — no backend changes.

   Loaded after style.css. Legacy header chrome is hidden (not removed)
   so existing app.js functions keep resolving their elements harmlessly.
