/*
  Global styles for the Stacksona landing page.  The palette is lifted
  directly from the React design provided in the canvas: purples and
  blues for accents against a soft neutral background.  Elements use
  generous padding and rounded corners to create a modern, friendly
  feel.  The fade‑up animation is driven via IntersectionObserver; see
  script.js for implementation details.  Cards in horizontal rows are
  animated in a cascade by setting the --delay custom property.
