/* The hamburger menu takes over earlier than the other breakpoints (1060px
   instead of 720px) because the full desktop header — brand + 5 nav links +
   1 CTA button — needs about 1040px to fit on one line. flex-shrink is
   disabled on the header's direct children and on each nav link (see
   .brand, .main-nav, .main-nav a, .header-cta) so a too-narrow viewport
   can't silently squash text into a wrap/overlap — it just falls back to
   the hamburger below this width instead. */
