/* ---------- MOBILE NAV (hamburger) ----------
   Below 760px there's no room for 7 links in a row, so instead of letting
   them wrap unpredictably (which is what caused the off-centre, jumbled
   nav) we hide the list behind a toggle button. The old approach also left
   the "Subjects" mega-dropdown positioned absolutely and off-screen even
   while invisible, which is what was quietly forcing the whole page to
   render zoomed out on iOS Safari; on mobile it's now rendered inline
   instead of as a floating dropdown, so it can't do that any more. */
