 * One-off importer: transcribe the large Cloud Empress tables from the source

 *   node import-tables.mjs <chaptersDir> <tablesOutDir>

 * The source chapters are markdown with pipe tables. This script only handles
 * the handful of tables that are too large or too comma-heavy to transcribe by
 * hand; the small tables were written directly and are not touched here.
