/* 
   SCROLL-REVEAL ANIMATIONS
   Usage: add .reveal (or variant) to any element.
          JS in app.js adds .is-visible when it enters the viewport.
   Variants:
     .reveal           default fade-up
     .reveal-fade      fade only (no movement)
     .reveal-scale     scale up from 93%
     .reveal-left      slide in from the left
     .reveal-right     slide in from the right
   Delays (chain on the same element):
     .reveal-delay-1  .reveal-delay-5  (100ms increments)
