/**
 * Semantic tuning — turn HIGH-LEVEL design knobs into concrete low-level token
 * overrides that `applyTokenOverrides` understands. This is what lets a user (or
 * the model) say "make it rounder / more compact / snappier" without knowing the
 * kebab-scale token names:
 *
 *   design {action:"tune", tune:{ radius:"lg", density:"compact", font:"Space Grotesk" }}
 *
 * Pure: returns an override map (bare keys → both themes). Merged into the kit's
 * active overrides exactly like `set`, so it stacks with raw token overrides and
 * flows into materialize + verify + the per-turn reminder.
