   Breakpoints
   -----------
   1440px  large desktop / laptop
   1280px  small laptop
   1180px  tablet landscape
   1080px  tablet — nav collapses, scroll-pinned sections unpin
    900px  small tablet
    760px  phone landscape / large phone
    560px  phone
    380px  small phone
   Plus a short-screen (max-height) query for the pinned about section and
   preference queries (reduced motion) at the end.
