/* BA Workstation motion layer (Ardito skin phase 3c, 29 Oct 2026). Loaded with ba-dark.css.
   Rules: transform and opacity only (no layout shift, nothing that delays input); every
   animation sits under prefers-reduced-motion: no-preference AND outside calm mode
   (html.ard-calm: Save-Data, 2G/3G, reduced motion; set by ardito-skin.js). Content above the
   fold is never hidden: only blocks that START below the fold are revealed on scroll, and
   ba-motion.js marks them (.bk-rv) only after first paint. Hover effects only where hover
   exists, so a tap on a phone never leaves a card stuck mid-effect. */
