   LCDH13 — Motion
   Entrance animations, tuned for a clear "one after another" cascade
   within each section (eyebrow → title → text → content) rather than
   everything fading in at once — while staying fast enough to never
   read as blocking (short absolute durations, early trigger, no
   external animation library — plain CSS + IntersectionObserver).
