/**
 * Island architecture runtime for Shopify themes.
 *
 * Walks the DOM for custom elements that match island files, then loads them
 * lazily based on client directives:
 *
 *   client:visible     — load when the element scrolls into view
 *   client:media       — load when a CSS media query matches
 *   client:idle        — load when the browser has idle time
 *   client:defer       — load after a fixed delay (ms value on the attribute)
 *   client:interaction — load on mouseenter / touchstart / focusin (or custom events)
 *
 * Directives can be combined; all conditions must be met before loading.
 * A MutationObserver re-runs the same logic for elements added dynamically.
