Version 7.3.0 - Kitsuneru evolved from basic subtitle overlay into a full language-learning toolkit, getting new fresh design overhaul, adding flexible per-row segmentation strategies, an Articles text reader (hover/click/selection modes), OCR (built-in + Tesseract.js with drag-and-drop and right-click support), and a heavily reworked YouTube integration with multiple display modes and cross-language cue-contamination fixes. Alongside new features, I ran major performance passes-fast-exiting content-script init in video-less iframes, speedifying lazily-loading modules, and fixing delay/offset persistence bugs on auto-load to keep CPU/RAM low and reliability high. The UI also got a full theming overhaul for that spicy theme-aware color-mix variation; finally expanded localization to 46 languages.
