Thmyl Fys Bwk Andrwyd 5.1.1 ✧ < Updated >
Test andrwyd → right shift: a→s, n→m, d→f, r→t, w→e, y→u, d→f → smfteuf — no.

Wait — known trick: fys = fsb if y→s is shift -6, but b unchanged. Unlikely. Test andrwyd → right shift: a→s, n→m, d→f,
Check mapping: t→t, h→h, m→e? No. Fails. Test andrwyd → right shift: a→s
But ROT-(-3): F(-3)=C, S(-3)=P, B(-3)=Y → CPY no.
