D.2: a little Bach-minuet chromaticism — applied dominants

Paul: "just a little. Think Bach minuet." The harmony organ had secondary dominants gated at adventure>0.5, so most genres never reached them and read as all-diatonic.

• Dose: +~0.75–1.3 non-diatonic tones per 8-bar phrase in the mild-to-mid band (≈ one applied-dominant moment per phrase), tapering at the extremes.

Verified: theory.test (monotonicity + voice-leading motion <3st both green); pipes; verify.sh with FRESH matrix (theory.js isn't a cache-key) = 240/240 diagonal-dominant
