/* ============================================================
   animations.css — Homepage motion/energy layer
   ============================================================
   Purely additive visual layer — no rule here changes layout,
   colors, or spacing that style.css already defines; everything
   is either a transform/opacity animation or a new self-contained
   section (Trust Bar, CTA Banner). Loaded AFTER style.css.

   HOW THE SCROLL-REVEAL CLASSES WORK (see animations.js):
     .scroll-fade-up / .scroll-fade-left / .scroll-bounce-scale /
     .scroll-slide-left / .scroll-slide-right — animations.js adds
     ONE of these to a target element, which sets its HIDDEN starting
     state (opacity 0 + an offset transform). When the element scrolls
     into view, animations.js adds .in-view alongside it, which
     transitions to the visible resting state. Each pair is defined
     together below for readability.

   ACCESSIBILITY: animations.js checks prefers-reduced-motion and, if
   set, never adds the hidden-state classes at all — elements simply
   render in their final visible position, no animation, no JS needed
   to "fix" anything.
