TextReplacer replaces only in plain-text segments (S8 split), outside
script/style bodies, inserts the replacement cleaned per field kind and
refuses any result whose tags, entities or references differ from the
original plus the inserted text. Unchanged strings are never cleaned.
Per page all or nothing with the tree_rev lock; Throwables are reported
per page (S10).
