Arc Relay

Arc Relay turns an intentional click into a brief geometric signal. Arm it from the popup on the current tab, then click a button, link or supported control. A transparent canvas draws a light segment around the actual element rectangle and fades it after the selected duration. Choose Perimeter, Corners or Echo path, three signal colors and a 300–1300 ms duration in the popup. The preview shows the visual language without inspecting a page. The script ignores disabled and oversized targets, never prevents the website's own click, and does not run automatically on every site. Link navigation may end a pulse early. Disarm removes the overlay and listeners. Reduced-motion preference suppresses new pulses.
