/* Vagai Silambam motion. Loaded after home.css.

   Feel: a spinning staff, quick strikes, graceful footwork, then stillness.
   Rules: transform and opacity only (so low-end Android phones stay smooth), with three
   deliberate exceptions the design asks for: the kolam stroke draw, the FAQ height and the
   number counters. Everything is behind the `motion` class, which the page only sets when the
   visitor has not asked for reduced motion. Without it (or without JavaScript) the page is simply
   shown in its final state. */
