# 03-accent <> Which line makes the rectangles that flash on the downbeat? Make that accent linger a little longer, without touching anything else. <> Starting AI conversation <> InspectRectSLStudy finished (7 ms) <> TraceRectSLStudy finished (400 ms) <> Waiting for model <> Evaluating adjustments needed **Evaluating adjustments needed** I need to make a minimal change from .22 to .34, without any plateau—no acceptable lingering there. The user seems to want an "accent linger" effect that lasts longer, so I need to ensure it falls enough. Since it’s all about getting one clear number, I should aim to capture this before any mandated changes take effect.

The top-row rectangles themselves are made on **lines 12–13 and 16–17**. Changed only its release time: **0.22 → 0.34 seconds**, so the accent lingers **120 ms longer**, including the delayed answers. Verified: only the accent’s height decay changed. The three cream/vermilion rows, your `#0e0a08` background, canon delays, and other beats remain unchanged. Compilation and visual comparisons passed.
