/*
  The nav drawer breaks earlier than the general tablet/mobile breakpoint
  (900px, not 768px) because the top-level nav list still doesn't fit the
  header on one line down to 768px at the full --fs-body size — text size
  was kept at the user's request rather than shrinking to --fs-small, so
  the drawer takes over sooner instead. Verified with Playwright (disabling
  the drawer's own transform/transition first, since measuring mid-
  transition gives bogus bounding rects): with 6 top-level items —
  Kezdőlap, Megoldásaink (dropdown, see below), Rólunk, Minősítéseink,
  Referenciáink, Kapcsolat — the list overflows starting ~860px and fits
  with margin from 900px up. Re-measure the same way if the top-level
  item count changes again; don't assume 900px still holds.
