Then add it to your interface:

import { GridLattice } from "@/components/ui/grid-lattice"

<GridLattice size={48} speed={1.6} />

Inherits text color. Accepts className, style, and a custom loading label. Respects reduced-motion preferences.

import type { CSSProperties, ComponentProps } from "react"

export type GridLatticeProps = ComponentProps<"span"> & {
  size?: number
  /** Duration of one complete cycle, in seconds. */
  speed?: number
  label?: string
}

export function GridLattice({
  size = 40,
  speed = 1.6,
  label = "Loading",
  className,
  style,
  ...props
}: GridLatticeProps) {
  return (
    <span
      role="status"
      aria-label={label}
      {...props}
      className={["grid-lattice-loader", className].filter(Boolean).join(" ")}
