Weak seed
A long phrase can cast a small shadow.
Stretch a toy source into a large-looking mnemonic and reveal the smaller set an attacker actually needs to enumerate.
12 displayed words have an effective source ceiling of 32 bits in this teaching model.
It looks like 128 bits. It searches like 32.
A deterministic encoder can spread a weak source across many words. It cannot make the original candidate set larger.

Width is not uncertainty.
An attacker can enumerate the 2^32 = 4,294,967,296 original states, regenerate each large-looking result, and ignore nearly every other possible phrase.
The tiles are deliberately invalid labels. This deterministic teaching model is not a wallet generator or cracking tool.
