/* ==========================================================================
   Footer clearance under the solid (fixed) header
   --------------------------------------------------------------------------
   Once the page is scrolled to the end, #header is fixed and 80px tall, so the
   footer's top edge lands hard against the top of the viewport. The TRADEFORMA
   wordmark sits only ~56px into the footer -- above 640px, where the footer is
   a single stacked column and so its tallest -- which put it *behind* the
   frosted bar: fully hidden on a 780-812px-tall viewport, sliced roughly in
   half around 836-840px, and clear only from ~844px up.

   Trimming the stacked footer's rhythm shortens it from ~821px to ~700px, which
   moves the wordmark down relative to the end of the document and clears the
   header at every height tested (664-1000px at 390px wide). Every other footer
   element stays on screen.

   Scoped to <=900px on purpose: the desktop 4-column footer is only ~378px tall
   and already clears the header with a wide margin.
