    "figma": "Designer handoff notes for the \"Repetition image hover trail\" element (Enrichr Library). Figma cannot run this JavaScript inside a design file, so use it as a motion reference and hand the code to a developer.\n\nThis is the \"Repetition image hover trail\" element from the Enrichr Library: Gradient image tiles that spawn a staggered trail of repeated copies chasing the pointer, each with a little more lag, then fading out on leave.\nPage: https://enrichr.dev/elements/repetition-image-hover.html\nMachine-readable spec: https://enrichr.dev/elements/repetition-image-hover.json\n\nWhat it does: On pointer enter the tile builds a small pool of copy elements, each a miniature of the tile artwork, and starts them one after another a few tens of milliseconds apart. A single requestAnimationFrame loop moves every copy toward the pointer position inside the tile using frame-rate independent easing, where copy number i uses a smaller easing factor than copy i minus one, so the copies string out behind the pointer like an echo. Opacity and scale step down along the trail and each copy tilts slightly with its distance from the pointer. On leave the copies keep drifting and fade out in order, and the loop stops once everything is hidden or has settled. Copies sit inside the tile with overflow hidden, so they never spill out of a clipped container.\nAccessibility: Tiles are links, so they stay keyboard reachable with a visible focus ring. Keyboard focus plays the same trail toward the tile centre without needing a pointer. The copies are decorative and hidden from assistive technology. With prefers-reduced-motion the trail is replaced by one static copy that fades in on hover or focus. Touch input does not spawn a trail.\n\nTunable settings:\n- Accent colour: color, default #e6ff55\n- Copies in trail: range 2 to 10, step 1, default 6\n- Copy size (% of tile): range 15 to 70, step 1, default 38\n- Trail lag: range 0.1 to 1.5, step 0.05, default 0.5\n- Fade out (ms): range 150 to 1500, step 50, default 600\n\nCurrent settings:\n{{SETTINGS}}\n\nFor the developer: Element contract (vanilla JavaScript, no dependencies):\n- The JavaScript defines a function mount(root, opts).\n- root is an empty container element.

Some elements also return replay().\n- The CSS classes all start with \"ef-\" so they will not collide with your styles.\n\nIn Figma:\n- Draw the resting state as a frame and the end state as a second frame; link them with Smart Animate to show the motion in a prototype.\n- Put the settings above in the frame's notes or Dev Mode annotations so the developer matches them.\n- Link https://enrichr.dev/elements/repetition-image-hover.html in the handoff: the live demo and the copy-ready code are there.
