/**
 * Input Rules Tests for TipTap Editor
 *
 * Tests that Markdown-style shortcuts work correctly in the editor.
 *
 * TipTap input rules are triggered by actual text input, not insertContent().
 * In headless tests, we simulate this by using the inputRules extension's
 * run function or by testing the resulting transformations.
 *
 * For integration testing, we verify the editor has the correct extensions
 * configured and that the expected node/mark types exist.
