 * Verifies the presentation-only contract from the agentflow syntax specification §10:
 * styling, class membership, view/collapsed state, icons, images and
 * element-mapping positions MUST NOT influence the semantic export. The
 * semantic model is what downstream tooling consumes when it needs to
 * understand what the diagram *means* without being influenced by
 * rendering choices.
