/**
 * Tests for WordPress import slug sanitization
 *
 * Regression test for emdash-cms/emdash#79: WordPress import crashes on
 * collections with hyphens in slug (e.g. Elementor `elementor-hf`).
 *
 * WordPress post type slugs commonly use hyphens (e.g. `elementor-hf`,
 * `my-custom-type`), but EmDash collection slugs require `[a-z][a-z0-9_]*`.
 * The fix sanitizes all unknown post type slugs so they conform to the
 * collection slug format, rather than trying to enumerate every plugin's
 * internal post types.
