Selecting an audio bus showed a Motion section offering tween editors. A bus has no transform, opacity or box, so every effect on that list moves nothing; the same is true of an `<audio>` clip. The panel's gate was "are the GSAP handlers wired", and `App.tsx` always wires them, so it was true for every selection. It now also asks what was selected. Audio keeps its timing — an `<audio>` clip is placed on the timeline like anything else — but the section is called Timing there and summarises its span instead of an effect count, because "Motion: 0 effects" on a sound is a category error. A bus loses timing too: it has no `data-start` and no duration, and its automation clock is composition time, so Start / Duration / End would be editing nothing. Gated on the TAG, not on `sections.animation`: a `div` with no tweens yet must still offer "+ Add", and keying the rename on `animationCount > 0` renamed the section for exactly that div — which the existing panel test caught. Keying it on `showMotionEffects` renamed it for an `img`, which wires no GSAP handlers. Both halves belong to the tag. `affordances.ts` carries the same two rules for anything reading the section list rather than the flat panel. The label pair is `motionSectionLabel`, in the module that owns the section it names, which is also what keeps `PropertyPanelFlat.tsx` under the 600-line ceiling.
