Original release notes

- 66 new social-media slang terms — the 網絡潮語 lesson grows from 44 to 110 entries (KAM, MM7, 觀濱, 上水, Siu4, rizz…), each with Jyutping, meaning and a real example.
- 25 classic Hong Kong slang expressions — 吹水, 食死貓, 放飛機, 淆底, 屈機, 掟煲, 冚唪唥 and more. That lesson now holds 151 entries.
- The daily reminder now arrives at the time you pick. It used to arrive about 24 hours after you switched it on; it now keeps your chosen time, even across daylight-saving changes.
- 224 missing translations added across 10 languages — pronunciation feedback, review buttons, locked-level hints and search no longer fall back to English.
- Updated underlying libraries and fixed the iOS build.
