/**
 * SplitText-lite: break an element's text into word/char spans carrying
 * `--sv-order` (and `--sv-count` on the container), so every order-driven
 * preset (entrances with stagger, `sv-reading`, `sv-range` slices) works
 * on text with no manual markup.
 *
 * Accessibility: the full text is kept as a visually-hidden first child
 * (aria-label is prohibited on generic roles like p/span/div. Axe
 * `aria-prohibited-attr`); the animated spans are `aria-hidden`. The original content is restored by the returned
 * function. Markup inside the element is flattened to text. Split plain
 * text, not rich fragments.
