Text Import & Vocabulary Extraction: Added a new text import functionality that automatically extracts vocabulary and supports dictionary integration. Randoms Feature Module: Introduced the "Randoms" module, which includes built-in Text-to-Speech (TTS) support and a new Chinese character lookup service.

We improved the way of random and effectiveness.

### New Features **Mandarin Text-to-Speech:** Added a native Chinese voice pronunciation feature. Tap the speaker icon on any Hanzi card to hear the character or phrase spoken aloud! **Adjustable Speech Speed:** Having trouble catching the pronunciation? Tap the speaker icon multiple times to cycle between Normal, Slow, and Very Slow speeds. **Session Sound Effects:** The flashcard experience is now fully immersive with sound effects for correct answers, wrong answers, button clicks, and a special congratulation sound when you finish a deck! **Practice Limit Controls:** Before starting a flashcard session, you can now toggle a setting to either practice a manageable batch ("Limit to 50 cards") or test your endurance and practice "everything" in the deck. **Deck Content Breakdown:** On the *Univers Randoms* dashboard, Chinese decks will now automatically calculate and display exactly how many single characters vs. multi-character phrases are inside. ### Design & UI Improvements **Improved Character Readability:** We updated the typography for Chinese Hanzi. Characters now render in a crisp, normal font weight, making complex strokes much easier to read and study. **Dashboard Redesign:** The main screen has been reorganized with a clean top-level menu to easily switch between your "Univers Randoms" (flashcards) and "Memorize what you see" (roadmap) modules. ### Under the Hood * Fixed a bug where the native iOS app version wasn't properly syncing with the Flutter configuration. * Improved memory management for audio players during rapid flashcard progression.
