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

import type { CSSProperties, ComponentProps } from "react"

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

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

          "--loader-size": `${size}px`,
