    "figma": "Designer handoff notes for the \"Draggable infinite grid\" 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 \"Draggable infinite grid\" element from the Enrichr Library: A wrapping grid of gradient tiles you drag in any direction with inertia, with tiles scaling slightly by distance from the centre.\nPage: https://enrichr.dev/elements/draggable-infinite-grid.html\nMachine-readable spec: https://enrichr.dev/elements/draggable-infinite-grid.json\n\nWhat it does: The script keeps one scroll offset for the whole field. It builds a block of tiles slightly bigger than the stage, and on each frame places every tile at its base position plus the offset, wrapped with a modulo so a tile leaving one edge re-enters at the opposite edge. That makes the grid endless without moving any DOM nodes. Dragging writes to the offset and records pointer speed; on release a requestAnimationFrame loop keeps moving the offset and multiplies the speed by a friction factor until it stops. Each tile is scaled down by its distance from the centre of the stage, and everything is applied as a translate3d plus scale transform.\nAccessibility: The stage is focusable and the arrow keys pan the grid, so it does not depend on a pointer. The mouse wheel also pans. Reduced motion keeps direct dragging but removes the glide and the centre scaling. The tiles are decorative; if yours carry links or captions, make them real links and keep them out of the drag handler.\n\nTunable settings:\n- Accent colour: color, default #e6ff55\n- Tile size (px): range 80 to 220, step 10, default 130\n- Gap (px): range 0 to 40, step 2, default 14\n- Centre scaling: range 0 to 0.7, step 0.05, default 0.35\n- Glide (friction): range 0.85 to 0.98, step 0.01, default 0.94\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.
