  /* Full-screen docked sheet, not a floating card — header at top, messages
     fill the middle, input pinned directly above the keyboard. Bottom tracks
     --avni-kb-inset (the derived keyboard height) so the input never ends up
     underneath it; falls back to the home-indicator safe area when closed.
     Top adds --avni-vv-top (visualViewport.offsetTop) on top of the safe
     area — iOS Safari shifts the *visual* viewport down to scroll a focused
     input above the keyboard without ever scrolling the document, so a
     fixed `top` anchored only to the safe area drifts out of alignment with
     what's actually visible, exposing the real page through the gap.
     Bottom subtracts that same --avni-vv-top back out of --avni-kb-inset —
     kb-inset is the *total* shrinkage of the visible window from its
     baseline, but part of that shrinkage is the exact same downward shift
     already spent on `top`. Counting it in both reserves that space twice,
     leaving the panel's bottom edge short of the keyboard by vv-top's worth
     of exposed page underneath, for as long as the keyboard stays open. */
