- "Sharp video and subtitles" (Settings → Player and the player settings card, on by default): the video output renders at the view's physical size (debounced, GPU rendering only), so libass, mpv's scaler and the shaders work at screen resolution; re-sent after media_kit's own reset on new video params, redrawn while paused. - Dev builds only (Settings → About → Developer): a danmaku preview (DanmakuLayer: free lanes in an upper band, density cap with a queue, equal crossing time, outlined text, avatars, own-line frame) over the real player or a stand-in picture, with samples, a random stream, live toasts, every knob and mock subtitles; and "Lift subtitles above the chat line and controls": Enter opens a stand-in chat line, bottom subtitles move up via mpv sub-pos while it or the control bar is up. - tool/make_sub_test.sh: a test video with a top \an8 sign, bottom dialogue and an SRT track.
