This conceptual note proposes a structural interpretation of CKM quark mixing within the framework of Triadic Mesh Dynamics (TMD). The text does not introduce a numerical model or attempt to fit experimental data. Instead, it highlights that the qualitative features of the CKM matrix — three generations, hierarchical mixing, and the presence of a CP phase — admit a natural geometric interpretation when viewed as projections between two triadic orientational frames representing layered quark structures in TMD. The note is intentionally limited in scope and serves as groundwork for future quantitative development once the baryonic module of TMD is fully established.
