What do I do with this?

Put circuit-trace-board-15665.css anywhere your page already loads CSS from — in Next.js that is app/globals.css, or any stylesheet with a <link> in your HTML.
Then put the class on the element you want it on: <button class="fx-v14-bg-circuit-15664">. The CSS does nothing until a class name in it matches something on the page.

Link the stylesheet, then paste the markup wherever you need it.

Motion safety

Static estimate, read from the CSS

Reduced motion: Guarded
Ships a prefers-reduced-motion block, so the loop settles into its end state for visitors who ask for less motion.
What it animates: Reflows
Animates left, top. The browser re-lays-out the page on every frame; prefer transform if you can.
Flashing (WCAG 2.3.1): Under 3 flashes/s
Its brightest loop is about 0.3 a second. Estimated from duration, iterations and keyframes, not from rendered frames.
Layout shift (CLS): May shift layout
Animates left, top on a box in flow, so content beside or after it can move. Measured in Chromium: layout-shift score 0.0002 across 15 shifts in 4 s, one preview with a neighbour beside it. Not a page-level CLS.

Every row is read from the shipped CSS. Only a figure marked measured came from a browser. Customizing the speed changes the timing, so recheck a customized copy. How it is computed

Where this fits

Full sections that use this kind of element.

Split Hero with Product PanelHeroes
Copy on the left, a drawn product panel on the right — the default hero for anything with an interface to show, with no image asset to host and no layout shift while it loads.
Newsletter Capture BandCTA Sections
Email capture with a four-state submission machine and an aria-live status line, so the outcome is announced and not just shown.
Centered Announcement HeroHeroes
A linked announcement pill over a large centered headline, dual CTAs and a wordmark strip — the hero for a product with nothing to screenshot yet.
