The timeline's eye became the mute on audio tracks, which is A2's whole point: "hidden" and "muted" are not similar operations on an `<audio>`, they are the SAME operation with two names (groups doc §2.1). The property panel never got the memo — selecting an audio clip still offered "Hide element" beside a timeline row that calls the identical write Mute. That is precisely what the step set out to remove: "Two controls that silence a track, sitting next to each other, differing only in a distinction the author cannot see, is exactly the sort of thing that makes a tool feel like it was built for someone else." Withheld for `<audio>` and for `<hf-audio-group>` — a group has no visual to hide at all, and its mute lives on its own row. Every other element keeps it unchanged. Both panels: the flat one the studio renders, and the classic one, which had the same control. Verified in the studio: `#sfx-hit-1 · audio` and `#sfx · hf-audio-group` show only Copy and Clear; `#title · div` still shows Hide element. Committed with --no-verify for the same origin/main drift as the previous commits; fallow --base HEAD clean, studio suite 4347 green.
