Deinterleave stereo stride · case 03
Halving the array treats interleaved input as planar.
Case contract
Split an even-length interleaved stereo array into left/right planar arrays.
Why this case matters
A pure Python local audio pipeline stage with explicit sample formats and frame conventions; no real-time device or signal-spectrum claims.
