Hero Inference

A large illustrative hero SVG for the inference-engineering motif — three FP32 blocks enter from the left, squeeze through a central funnel, and re-emerge on the right as smaller, brighter INT8 blocks while a throughput counter snaps from 1x to 4x. Theme-driven via currentColor + a single accentColor prop; reduced-motion users see a static end state.

Usage

import { HeroInference } from "@craft-bits/core/svg/hero-inference";
 
<HeroInference size={400} />
 
// Tint via the parent text color.
<div className="text-cb-accent">
  <HeroInference />
</div>

Understanding the component

  1. Continuous storyboard. A single useEffect schedules the full ~8s cycle: entrance fade, FP32/INT8 labels appear, three blocks stagger through the funnel (large → small, base color → accent), a ghost block oscillates slowly on the left for speed contrast, the throughput counter snaps from 1x to 4x, fade, loop. Every timer is cleaned up on unmount and when reduced-motion changes.
  2. Motion values, not re-renders. Each pipeline block's position, scale, color crossfade, and opacity are driven by motion's useMotionValue + useSpring so the React tree never re-renders during the loop. Springs come from @craft-bits/core/motion (SPRINGS.slow for the pipeline traversal, SPRINGS.smooth for shrinkage and crossfade, SPRINGS.bouncy for the throughput counter).
  3. Theme-driven color. The funnel strokes, base block fill, FP32 label, ghost block, axis, and caption all use currentColor, so the host tints the whole illustration with any text-cb-* utility. The accentColor prop tints the post-funnel blocks, squeeze glow, INT8 label, fast chevrons, and 4x readout — any CSS color (including var(--color-accent-500)).
  4. Reduced-motion safe. When prefers-reduced-motion: reduce is set, the loop short-circuits to a static end state — funnel + labels visible, three INT8 blocks parked on the right, throughput reading 4x. No timers, no animate() calls.

Variants / Examples

// Compact thumbnail.
<HeroInference size={200} />
 
// Explicit accent color.
<HeroInference size={480} accentColor="var(--color-accent-300)" />
 
// Custom hex.
<HeroInference accentColor="#8b5cf6" />

Props

PropTypeDefaultDescription
sizenumber400Pixel width. Height is computed from the 400×280 aspect ratio.
accentColorstring'currentColor'Any CSS color. Tints the output blocks, squeeze glow, INT8 label, and throughput counter.
classNamestring—Extra classes merged onto the root <svg>.
...restSVGAttributes<SVGSVGElement>—Other SVG props forwarded to the root.

Accessibility

  • The root <svg> carries aria-hidden="true" — the illustration is decorative; pair it with a visible heading or caption in its surrounding context.
  • Motion respects prefers-reduced-motion: reduce: the loop short-circuits and renders a static end state.
  • All colors flow from currentColor + the accentColor prop, so contrast tracks the consumer's text and accent tokens — no hardcoded hex values.
