v2.4.5
New Features
- Sentence length filter (#33): drop cards whose example sentence exceeds an audio-duration or character cap. Applied after i+1 sentence selection so the cap binds the final chosen sentence.
- Theme variants grouped by family: light/dark variants nest under one expandable row in Settings > Themes. Tri-state family star bulk-favorites the whole group in a single click.
- Yomitan-format frequency dictionaries: Settings > Word Filtering > Frequency Source now accepts a Yomitan freq zip alongside
frequency.csv. Rejects malformed archives (format != 3, non-positive ranks) with a clear error. - Background-threaded frequency import with modal progress, cancel, and overwrite confirmation.
Fixed
- Theme colours now apply to the Analytics tab (was inheriting host palette).
