/**
 * `<dt-markdown-editor>` — full WYSIWYG markdown editor powered by Milkdown.
 *
 * The component lazy-loads Milkdown on first use, injects the required editor
 * styles into its shadow root, and exposes a simple `value` property that reads
 * and writes markdown.
 *
 * ## Attributes
 * - `placeholder` — empty-state hint text
 * - `readonly` — when present, disables editing
 *
 * ## Properties
 * - `value` — JS-only markdown value for get/set access
 * - `readonly` — boolean reflection of the `readonly` attribute
 *
 * ## Events
 * - `dt-change` — debounced content updates with `{ value }`
 * - `dt-focus` — fired when the editor gains focus
 * - `dt-blur` — fired when the editor loses focus
