PromptSuggestions doesn't have three separate layouts. It has one motion.button per suggestion and a lookup table that decides how the wrapper arranges them:

The button itself branches once, on isChip, to pick between a pill className and a card className. There is no separate component per variant:

className={
  isChip
    ? "group inline-flex items-center gap-1.5 rounded-full border border-border bg-card px-3 py-1.5 …"
    : "group flex items-start gap-2.5 rounded-xl border border-border bg-card p-3 …"
}

That's why hint only renders outside chips ({suggestion.hint && !isChip ? … : null}): a chip is one line by design, a card has room for a second. Swapping variant never remounts a different tree; it only changes which layout classes and which of these two branches apply.

Every suggestion animates in with the same spring. The only thing that changes per item is delay:

320/32/0.9 is a slightly underdamped spring, the same one used in GodUI's other enter animations (badges, command palette rows), so each card overshoots its resting position by a hair before settling instead of easing to a flat stop. index * 0.05 is the entire stagger. There is no staggerChildren and no parent motion.div orchestrating children; each button computes its own 50ms offset from its position in the array. Reduced motion collapses delay to 0 and swaps initial to false in the same expression. The spring is gone and the layout stays.

Hover is a second, independent motion system in plain Tailwind (not Framer), and it only touches transform and opacity:

-translate-y-px and -translate-y-0.5 lift the item on the compositor, with no top, no margin, nothing the browser has to re-lay-out. The arrow follows the same rule from the opposite direction: it's rendered at opacity-0 -translate-x-1 on every card from the start, so revealing it on hover is a transform + opacity flip, not a mount. Its box never changes size, which is why neighboring text never reflows when the arrow shows up. Cards also swap shadow-2xs for shadow-md on hover. That is the one paint property, and it is safe here because it's gated behind a single hovered element rather than something looping on scroll.

Setting loading doesn't hide the component behind a spinner. It renders the same container with skeleton placeholders sized per variant:

<div className={CONTAINER_BY_VARIANT[variant]}>
  {Array.from({ length: skeletonCount }).map((_, i) => (
    <div
      key={i}
      className={`rounded-xl border border-border bg-muted/40 motion-safe:animate-pulse ${
        variant === "chips" ? "h-9 w-32" : "h-16"
      }`}
    />
  ))}
</div>

Because it's the same CONTAINER_BY_VARIANT[variant] wrapper, the skeleton grid occupies the same footprint the real suggestions will once they arrive, so swapping loading off never causes a layout jump. motion-safe:animate-pulse keeps the shimmer itself opt-out under reduced motion, same as the entrance spring above.

One array of suggestions, one variant string picking a wrapper class, one spring staggered by index, and a hover system that only ever moves transform/opacity.
