Prompt

A magenta #db2777 button, 10px radius, white bold 15px text with a faint white text glow, 14px by 28px padding. A translucent magenta ring expands from the edge to 14px and fades out every 1.6 seconds, like a heartbeat. Hover darkens to #be185d and doubles the beat rate; active stops the ring and scales to 0.97. Focus 2px magenta outline offset 5px.
