/* iOS Safari sticky safety nets ---------------------------------------------
   Three things older / quirky iOS Safari builds need to engage `position: sticky`:
   1. The legacy `-webkit-sticky` value (cheap to add; modern Safari ignores).
   2. The `top` declared right after `position` so the rules are colocated.
   3. A guaranteed document min-height so the body is taller than the viewport
      and the sticky element actually has something to stick TO.
   Putting the rule outside the @media block applies it at every breakpoint. */
