/**
 * Validate a generated iXBRL årsredovisning against the official taxonomy
 * package using Arelle (https://arelle.org): layer 2 of the validation
 * stack (layer 1 = pre-flight rules engine, layer 3 = Bolagsverket
 * `kontrollera`).
 *
 * Usage:
 *   npm run validate:ixbrl -- path/to/arsredovisning.xhtml
 *
 * Arelle discovery order:
 *   1. `arelleCmdLine` on PATH (pip install arelle-release)
 *   2. `python -m arelle.CntlrCmdLine`
 *   3. docker image `arelle/arelle` (mounts the file + taxonomy package)
 *
 * Exits 0 with a notice when Arelle isn't available (CI machines without
 * Python shouldn't hard-fail), 1 on validation errors, 2 on usage errors.
