/**
 * Remark plugin that drives per-document numbered-heading behavior via frontmatter.
 *
 * Wire it into your Docusaurus docs preset:
 *
 *   const { remarkFrontmatterToggle } = require("docusaurus-numbered-headings");
 *   // ...
 *   docs: { remarkPlugins: [remarkFrontmatterToggle], ... }
 *
 * Then in any MDX file, control numbering with the `numbered_headings` frontmatter
 * key:
 *
 *   ---
 *   numbered_headings: false              # disable auto-numbering on this page
 *   numbered_headings: "iso-2145"         # force ISO 2145 (1, 1.1, 1.1.1)
 *   numbered_headings: "usa-classic"      # force USA Classic (I, A, 1, a)
 *   numbered_headings: "spanish-forense"  # force Spanish forensic (I, Primero.-, 1, a)
 *   numbered_headings: true               # explicit default (same as unset)
 *   ---
 *
 * When set, the plugin wraps the document body in a `<div className="…">` carrying:
 *   - `disable_numbered_headings`         for `false`
 *   - `numbered_headings_iso_2145`        for `"iso-2145"`
 *   - `numbered_headings_usa_classic`     for `"usa-classic"`
 *   - `numbered_headings_spanish_forense` for `"spanish-forense"`
 *
 * Plugin CSS recognizes those classes and applies (or suppresses) the right
 * counters. The right-rail Table of Contents is scoped via `:root:has(...)`
 * since it lives outside the wrapped document body.
 *
 * Compatible with Docusaurus 3+, which exposes parsed frontmatter on
 * `file.data.frontMatter`.
