Bits and ordinary algorithms.
Conceptual browser-only model. PQC runs on ordinary computers; this is not an ML-KEM implementation.
POST-QUANTUM MIGRATION IS A SYSTEMS MISSION.

Bandwidth, memory, certificates, protocol limits, hardware, and interoperability can matter—not raw bytes alone.
MIGRATION CONTROL ROOM
Assign a posture to each fictional system, then run a nuanced assessment.
