/* ============================================================
   DYNAMICS
   The site had one level: black ground, bone type, red hairline,
   every section, every page. Mastered flat. This gives it range.

   .inv     printed on bone - the loudest move, once a page
   .redslab    red as a field, not a fleck - the closing CTA
   .still   silence - the field stops, one steady line
   .mega    the one enormous word per page
   .split   the grid breaks - image bleeds off the left edge
   .spine   wayfinding rail  +  #prog reading progress

   Palette is unchanged: black, bone, #CC2229. Only the
   proportions move.
