 * left alone because guessing whether arbitrary text is a person's name is too
 * inaccurate. The string redactor uses a protect-first strategy (mask IDs with
 * opaque placeholders before any transform runs, restore them byte-identical
 * afterwards), and the structure-aware walker additionally protects leaf
 * values by key name.
