type: added area: mining

• Added optional pre-generation timing review for word, sentence, and audio cards with a compact speech-weighted waveform that flattens steady background noise so dialogue edges are easy to see, clearly labeled mined-line boundaries, drag and keyboard adjustments, audio preview with a sweeping playhead that plays the clip to its true end even on high-latency outputs such as Bluetooth headphones, exact screenshot and AVIF timing, cancellation choices that include keeping a card without media, and a session-only runtime toggle.
• The timing review can pull any number of previous and next subtitle lines onto the card: P/N (or the Prev/Next steppers) add lines one at a time, Shift removes them, the sentence preview highlights exactly what the card will contain, and the clip range and line boundary markers on the waveform follow the added lines automatically.
