/* ==========================================================================
   Corporate Projukti — Redesign :: Motion layer

   Everything here is decoration. The page is complete and readable with
   this file absent, with JavaScript off, and under prefers-reduced-motion
   — the block at the foot of this file switches all of it off.

   Two rules from the design contract constrain what is allowed:
     · a slab cell is never transformed — it tears the shared hairlines,
       so cell feedback stays light and colour only;
     · inside a slab, reveal is fade-only for the same reason.
   Movement therefore lives on non-slab elements and on parts *inside* a
   cell (icon tile, arrow, numeral), never on the cell itself.
   ========================================================================== */

/* ==========================================================================
   REVEAL VARIANTS
   The base fade+rise lives in system.css. These are opt-in via
   data-reveal="…" for elements outside a slab.
