/**
 * Markdown → board elements (the inverse of scene.ts `extractMarkdown`).
 *
 * Turns a Markdown document's block structure into placeable board
 * elements: `$$…$$` blocks become display formulas, standalone `$…$` blocks
 * become inline formulas, everything else becomes text. Blocks are stacked
 * vertically; the host decides final placement (elements start at a given
 * origin and flow downward).
 *
 * This is deliberately self-contained (no @moraya/core ProseMirror parse):
 * the block grammar we need is small, and staying dependency-free keeps the
 * conversion usable in any host without pulling the editor schema. The
 * @moraya/core peer stays optional for richer future use.
