Preserve the source audio's tempo, key, acoustic space, dry production, four-note motif, and distinctive palette of harpsichord, felt piano, pizzicato cello, brushed drums, and restrained tape texture. Do not restart or abruptly change style at the edit point. Gradually develop the motif through a slightly tenser harmonic turn, add a subtle bass-clarinet counterline and crisp rim-click pulse, then reduce the arrangement into a concise, authoritative final cadence.
