/* 90-foot Stone Decoder: the tool on /90-foot-stone-decoder.
   Scoped to .sd; uses the site variables with fallbacks.
   Layout (Oct 2026, third round): questions left and options right, both always visible; below
   them the Run button, then the results in a fixed place. Nothing is fixed to the screen.
   Motion: only opacity and transform, and none under prefers-reduced-motion. */
