/* =========================================================================
   Natural Carr — portfolio stylesheet.
   No external fonts or imports, so the page can be routed to any domain.

   LAYOUT: a full-viewport "deck". Each <section class="panel"> fills the
   screen; navigating crossfades the current panel out and the next one in.
   Panels taller than the viewport scroll internally and only jump to the
   next/previous section once you hit the top/bottom edge.

   Sections below, in order:
