Replaces every measured per-person value in a rendered page with a named slot.
The safety property is byte equality, not this pattern list: the harvest normalises the same

(normalisedShellsAgree). So the list may be incomplete without being unsafe; omitting a
pattern costs a shell, never a disclosure.
