📜 Changelog

Modular Download Engine: Refactored the core download logic to eliminate "God Functions", ensuring better stability and maintainability.
Enhanced Resilience: Added smart 403 fallback mechanisms for strict HLS segments and verified robust pause/resume functionality.
UI Polish: Updated FAB aesthetics with a modern squircle design and improved progress bar visualization.

Premium Gold Theme: Implemented a new, sleek design system with gold accents, enhanced typography, and micro-animations.
Dynamic Progress Engine: Improved download scheduler with verified percentage tracking and gold-gradient filling.

v1.3.0

HLS Enhancements: Improved playlist enrichment and resolution detection.
