   Concept: a live "classical -> post-quantum" migration. The
   left column states the promise; the right column visualises
   it (classical algorithms struck out and re-encrypted to PQC
   under a scanning beam, with Harvest-Now-Decrypt-Later shown
   as neutralised). Uses the site theme tokens from styles.css.
