/**
 * Ordered registry of DOM transformers applied during `postProcess()`.
 *
 * Order matters:
 *  1. Accordion      — must run early so nested content is moved before other
 *                      transformers query it.
 *  2. Citation       — inline markers must be resolved before bibliography
 *                      anchors are attached, so the `#ref-<key>` hrefs align.
 *  3. Bibliography   — consumes the ordered keys produced by the citation step.
 *  4. Mermaid        — must run BEFORE `highlightCode`: it converts
 *                      `<div data-component="mermaid">` into `<pre class="mermaid">`,
 *                      and the highlighter explicitly skips `pre.mermaid`. If
 *                      this ran after, the highlighter would try to syntax-color
 *                      the mermaid source.
 *  5. HighlightCode  — runs Shiki over every remaining `<pre><code>`.
 *  6. HtmlEmbed      — independent; converts placeholder divs into iframes.
 *  7. IframeEmbed    — independent; converts placeholder divs pointing at a
 *                      remote URL into a standard `<figure><iframe src=...>`.
 *  8. HfUser         — independent; converts atomic placeholder divs into
 *                      Hugging Face user profile cards.
 *  9. Math           — renders the empty `data-type="inline-math"/"block-math"`
 *                      placeholders into static KaTeX HTML. Runs before
 *                      Footnote so math inside a footnote is captured rendered.
 * 10. Footnote       — runs last so collected texts include those inside every
 *                      other transformed block (tables, callouts, accordions...).
