/* ============================================================
   MOBILE NAV — hamburger ("pancake") toggle  v20 (2026-08-05)
   Icon taken from metlife.com's live mobile header, measured
   in-browser: their SVG sprite icon-menu/icon-close, rendered
   20x20px in MetLife navy #003652, full-width bars swapping to
   an X when open (an icon swap, not a morph — that is how
   MetLife does it). Menu drops as a full-width white panel
   under the sticky header. Desktop nav is untouched.

   These rules sit at the end of the file on purpose: they
   override the earlier <=760px header rules at equal
   specificity by source order.
