/*---*\
Icon Buttons
Icon cards in a grid or slider with white, light grey, or navy backgrounds.

KEY FEATURES:
- Desktop grid is 4 columns at 424px square; 1366px is 3-across at 450px square
- Desktop cards stay square; long body text scrolls inside the card
- Tablet grid is 2 columns and hugs the tallest card
- Mobile slider shows 1 card at 412px with no adjacent peek
- Mobile grid stacks unless there are 5+ cards (then it becomes a slider)
- Product single + slider (.iconbtns--stack-until-desktop): Slick at 1200px+;
  tablet stacks 2-col; mobile stacks 1-col
- Linked cards hover green and invert icon, copy, and CTA
- Cards without a link stay static with no hover fill

IMPLEMENTATION NOTES:
- Behavior follows docs/fed-specs/innerpage-blocks/icon-buttons.md
- Uses fx_slick for slider layouts
- Card icons come from the Icomoon picker (.icon-* classes) or an uploaded image
- .iconbtn--static is used when no link is set
- Product stack column styles target .iconbtns--stack-until-desktop
