/* Sharkie home page. Light, airy, one lilac accent (the app's own palette), in the spirit of the Open Send site.
   Everything draws its FINAL state by default; the hero chat animates from hidden only under .play (set by site.js while it is on screen),
   so with no script or with reduced motion the page is complete. */
