/* ============================================================================
   mv-drill.css — Abt.com-style hamburger DRILL-DOWN menu.
   The panel is built entirely client-side by mv-drill.js from the category tree
   already in the DOM inside .mv-megamenu (no backend / SQL / AJAX).

   ADDITIVE & REVERSIBLE:
   - Keeps the desktop .mv-megamenu horizontal bar exactly as-is.
   - Shows ONE hamburger at every breakpoint that opens a separate off-canvas
     drill panel (.mv-drill).
   - Reversibly neutralises the legacy "#header-menu becomes the drawer" behaviour
     below 1200px so the new panel is the only drawer (bar stays hidden there, as
     before — the bar still shows >=1200).
   Remove this file + js/mv-drill.js + the two <sys:*> includes to fully revert.
