/* Barnicle Productions — production motion + visual-module styles.
   Companion to motion.js. Failure-atomic: the html.motion gate class is added
   only by motion.js AFTER its reveal observers are wired, so if that file is
   missing/blocked/broken nothing here hides content. All hiding is scoped to
   screen (print always shows everything) and to prefers-reduced-motion:
   no-preference (reduced-motion users get calm static pages). */
