 *   0  title        Assembly / kit name (used as the liberty content title)
 *   1  description  Plain-text description (stored as content body)
 *   2  KLPR         Kitlocker price (stored in xkey, max 32 chars)
 *   3  KLURL        Kitlocker datasheet URL (stored in xkey_ext, max 250 chars)
 *
 * Existing assemblies (matched by title) are skipped unless cleared first.
 * KLPR / KLURL xrefs are only inserted when the column is non-empty.
