Email masking

Masks local parts while preserving domain visibility.

Phone masking

Masks sensitive digits while keeping format and suffix visibility.

Builder-style API

Enable email/phone masking and mask character explicitly before processing.

Install and start

Use the tagged source checkout while the opam repository package is planned, load the OCaml API, and run the minimal example below. It enables both masking rules explicitly and records the expected output.
