/* IDFX public site.
   Brand palette: charcoal #1a1a1a ground, slate #222831 surfaces, periwinkle
   #99aaff as the one accent, #f1f1f1 / #d9d9d9 type. Everything else is
   derived from those. Mobile-first; nothing may scroll sideways at phone width.

   Motion: things arrive quickly and settle slowly, nothing bounces. Every
   animation also works without JavaScript (content is visible by default and
   site.js only adds the entrance), and all of it stops under reduced motion. */
