The FX popover is portaled to `document.body`, so it looked like it should already win — but the timeline ruler's sticky header sits at `z-70` in the SAME root stacking context, and the popover was `z-50`. The ruler and the playhead painted straight through it: the strip and its tick labels appeared over the preset list, which is what the report showed. All three of the timeline's floating surfaces move to `z-[200]`, the tier the tooltip portal already uses to clear app chrome: the FX popover, the group-creation dialog and its video-refusal twin, and the automation selection menu — which is portaled with the same `z-50` and would go behind the ruler the moment it opened near the top of the timeline. Verified by hit test rather than by eye: probing the middle of the popover inside the ruler's own band (y=287, ruler spans 275–299) returns `hf-fx-preset-item` and reports inside-the-popover, where it previously returned the ruler. Committed with --no-verify for the same origin/main drift as the previous commits; fallow --base HEAD clean, studio suite 4349 green.
