/**
 * TextSplitter - Split text into animatable elements
 *
 * Splits text content into chars, words, or lines wrapped in spans.
 * Supports nested splitting (e.g., 'chars,words' = words containing char spans).
 *
 * Preserves existing element structure — inline elements like
 * `<span class="accent">word</span>` keep their wrapper and styling.
 * Only text nodes are replaced with split spans.
 *
 * Usage:
 *   const elements = TextSplitter.split(element, 'chars');
 *   const elements = TextSplitter.split(element, 'words');
 *   const elements = TextSplitter.split(element, 'chars,words');
 *
 * Revert:
 *   TextSplitter.revert(element);
 *   TextSplitter.revert(element, consumer); // reference-counted
