/*---*\
Image Buttons
Image cards linking to category or application pages.

KEY FEATURES:
- White or navy section backgrounds
- Desktop grid (3 columns) or slider (3 slides)
- Tablet and mobile always use a slider (1 centered slide)
- Hover overlay, description, and Learn More tab on desktop (linked cards)
- Cards without a link show title and description with no CTA or hover
- Focused slider card shows description by default

IMPLEMENTATION NOTES:
- Uses fx_slick for slider layouts
- CTA tab slant is clip-path, not an extra asset
- Card images use .object-fit from trumps.css
- .image-button--static is used when no link is set
- Image scale is clipped on .image-button__media so the CTA slant
  can extend past the card edge without a hairline seam
\*---*/

/* Clip image scale on the card only -- overflow on the section clips the
   GSAP shell transform and can make the whole slider look like it vanished. */
