    "figma": "Designer handoff notes for the \"Image grid motion on pointer move\" 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 \"Image grid motion on pointer move\" element from the Enrichr Library: A background grid of puzzle-piece tiles that scale in from the centre and then drift against the pointer, each tile with its own reach so the whole grid shears and fans.\nPage: https://enrichr.dev/elements/image-grid-motion.html\nMachine-readable spec: https://enrichr.dev/elements/image-grid-motion.json\n\nWhat it does: A vanilla port with no GSAP. The pointer position over the frame is turned into a -1 to 1 pair, and one shared value is lerped toward it every frame. Each tile multiplies that shared value by its own random reach on x and y, plus an optional rotation, and writes a single translate, rotate and scale transform. The intro scales the tiles from 0.7 to 1 and fades them in with an exponential ease, delayed by each tile's distance from the centre. The rAF loop sleeps once the intro has finished and the grid has settled, and wakes on the next pointer or key event.\nAccessibility: The frame is focusable and arrow keys nudge the grid, so the effect is not pointer only; Home or Escape recentres it. The tiles are decorative and hidden from assistive tech. Under reduced motion the tiles appear in place with no intro and no drift. Keep the foreground text on a darkened scrim so it stays readable over the moving tiles.\n\nTunable settings:\n- Accent colour: color, default #e6ff55\n- Drift (px): range 0 to 120, step 2, default 50\n- Smoothing: range 0.02 to 0.25, step 0.01, default 0.07\n- Rotation (deg): range 0 to 20, step 1, default 0\n- Columns: range 3 to 8, step 1, default 6\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/image-grid-motion.html in the handoff: the live demo and the copy-ready code are there.
