Summary
danae404 works almost entirely in the media text-track stack across WebCore and Platform — WebVTT cue positioning and rendering, VTTRegion, caption display modes, and the accompanying WPT imports and LayoutTests flake cleanup. The record is feature and spec-conformance work rather than security or hardening, with a recurring emphasis on the cue layout algorithm itself: float-vs-int coordinates, overlap avoidance distance, and hiding cues that fall outside the video rendering area. Where to look next: text track lifecycle changes — `removeTextTrack()` and the simultaneous display-mode/language switch fix that left a stale track enabled — since track teardown and state transitions are being actively reworked there.
