/**
 * Bilbordia Core — copy-to-clipboard visual feedback (1.2.5+).
 *
 * The handler in copy-to-clipboard.js toggles .is-copied on the clicked
 * element for 1.5s after a successful copy. This stylesheet paints a green
 * flash that fades out over that window, giving the user a clear
 * "copied!" confirmation without disturbing the visible text content
 * (matches the legacy `Method 4` background-flash UX from the original
 * standalone copy-to-clipboard.js).
 *
 * Selector is scoped to `[data-bskz-copy-button]` so unrelated elements
 * that happen to use `.is-copied` for other reasons aren't affected. The
 * keyframes set the background to solid green at 0% then fade to
 * transparent at 100%, so when the animation ends the element's normal
 * background returns naturally — no need to track the original color.
 *
 * Sites that want a different color can override:
 *   [data-bskz-copy-button].is-copied {
 *       animation-name: my-custom-flash;
 *   }
 *   @keyframes my-custom-flash { 0% { background: #abc } 100% { background: transparent } }
 *
 * Or disable the flash entirely:
 *   [data-bskz-copy-button].is-copied { animation: none; }
