/* Luxify Home — the lower half of the home (index.html) and the portfolio (index + projects.html).
   Driven by js/lower-story.js (timeline + fly) and js/portfolio.js (floating cards + viewer).
   Contract: WITHOUT .is-live (no JS, reduced motion, phones) the timeline is a vertical list of six cards, the word
   is a static marble heading and the portfolio is a plain collage / swipe row. .is-live pins the timeline and the
   fly section and gives them --p (0..1); every animated property is transform / opacity / clip-path. */
