/* ════════════════════════════════════════════════════════════════════════════
   IMungro — Page Reveal Animation (v2.3.4)
   Gentle, calm page transitions: subtle fade + slight upward drift.
   The body content starts invisible, then eases in over ~0.6s.
   Each major content block fades in with a staggered delay for a
   layered, unhurried reveal — never flashy, always calm.
