/* ============ MOTION LAYER ============
   Site-wide upgrades on top of styles.css. Everything is scoped under
   html.fx (set by motion.js), so without JS the page is the old one.
   - masked word reveals on section titles
   - scroll-lit "More than yesterday" statement
   - reasons as a sticky stack of layered cards (mobile)
   - gallery lightbox that grows out of the tapped photo
   - reading-progress line inside the nav capsule */
