/**
 * Icon — SVG sprite consumer. Figma: Go Flow Design System → node 1188:3323.
 *
 * Renders a single <svg><use href /></svg> pointing at the sprite. Every icon
 * inherits color from currentColor, so pass `color` or set CSS `color` on any
 * ancestor.
 *
 * Sprite path resolution order:
 *   1. spritePath prop (per-instance override)
 *   2. window.VENDOO_ICON_SPRITE (global override — set in HTML before load)
 *   3. default: "../../assets/icons.svg" (relative to the document loading it)
 *
 * Accessibility:
 *   - Default: aria-hidden="true" (decorative — wrappers like IconButton carry the label)
 *   - Pass aria-label → becomes role="img" with the label announced to screen readers
 *   - Pass title → renders a <title> child for native SVG tooltips
 *
 * Dev warning: when window.VENDOO_ICON_NAMES is present, unknown names log once.
