Kt20-y-multi-v2.0 Update Guide

The kt20-y-multi-v2.0 update reads like a careful recalibration — not a flashy reinvention, but a thoughtful reweighing of what matters. It’s the kind of release that betrays a focus on refinement: smoothing rough edges, tightening interactions, and letting existing strengths speak with more clarity. Where earlier iterations chased features, this one feels more deliberate, privileging coherence over accumulation.
