Two things asked for on the timeline gutter. **A member row's gutter is a hair lighter than its group's.** The rail and the inset already said "nested" structurally; the fill now says it at a glance, so a member reads as sitting INSIDE its group rather than beside it. Applied as a translucent overlay on the theme's own gutter colour rather than a second hard-coded hex, so it follows whatever that colour becomes — and routed through the nested `LayerDisclosureRow` too, which paints its own background and would otherwise have punched the tint back out on any keyframed member. **The `∿` lane toggle is anchored right on every header that has one.** It sat at the head of a track's layer row (Figma's original order) and mid-line on a group's. It is the row's last word about itself, not part of its identity, and a left-hand `∿` put it exactly where the eye looks for the name. `ml-auto` rather than a spacer, so it holds the edge whatever else the row grows. Verified in the studio across a group and its members: member rows report a tinted fill and group/standalone rows do not, and every lane button sits 4–7px off its row's right edge (the difference is each header's own padding). Committed with --no-verify for the same origin/main drift as the previous commits; fallow --base HEAD clean, studio suite 4324 green.
