/**
* Feature Section Card Animator
* Staggered scroll-reveal entrance + icon pop-in for .feature-section cards.
* Coordinates with the main.js scroll-hidden/visible system:
* 1. Sets --scroll-delay CSS custom property on each card so main.js's
* scroll-visible transition fires at staggered intervals.
* 2. Uses MutationObserver to detect when scroll-visible is applied, then
* triggers the icon-pop animation on the card's .feature-icon.
* 3. Resets the delay to 0s after the entrance so hover interactions stay snappy.
