+- Broadcast-style Japanese caption tracks (Crunchyroll JA subs) that split one sentence across two positioned events now publish it as a single line, so `preserveLineBreaks: false` flattens it, the sidebar lists it once, and mined sentences are whole. Rows from two different speakers, sound effects, and labeled turns still stay on separate lines.

+- Jellyfin subtitle files now load with zero mpv delay instead of inferring and saving an offset from Japanese and English cue timelines.

+- Multi-line copy and mining now select backward from the current subtitle in timeline order after seeking, instead of copying lines in playback encounter order. Jumping back to a short previous line also counts as a seek with external subtitle files, so that line becomes the current one.

+- Senren note type support for duplicate-card field grouping: enable `ankiConnect.isSenren` to merge duplicate mined cards using Senren's scene-switching markup, with grouped sentence, furigana, audio, picture, and miscInfo entries.
+- Senren field grouping supports the same auto/manual/disabled modes as Kiku, including the manual merge modal, and is mutually exclusive with Kiku (only one can be enabled at a time).

+- Copying the current subtitle, Anki sentence mining from recent lines, and immersion stats no longer include the separate furigana lines that broadcast-caption ASS files place above a word; recorders now use the same furigana-free text the overlay displays.
