🚀 KeyFlow v3.0.0 — Production UI/UX Redesign & Extraordinary Features Studio
We are thrilled to announce the official release of KeyFlow v3.0.0, a monumental milestone transforming KeyFlow into a world-class, production-grade desktop typing studio with high-density spatial layout, advanced typography, and sub-millisecond local telemetry.

✨ What's New in v3.0.0

1. 🎨 Obsidian Glass Design System & Advanced Typography
   4-Tier Elevation System: Deep obsidian dark palette (#070913, #0a0f1d, #10182e, #16213e) paired with fine sub-pixel borders (rgba(255,255,255,0.06) to 0.14) and backdrop glass blurs (backdrop-filter: blur(20px)).
   Precision Typography: Display headings in Outfit, UI copy and telemetry in Plus Jakarta Sans and Inter, and prompt text in JetBrains Mono and Fira Code.
   Micro-Interactions: Mechanical keycap press bounces, metronome pulse animations, active key glows, and sub-pixel caret pulsing.
2. ⚡ Distraction-Free Practice Studio
   Live Telemetry HUD: Prominent real-time Speed (WPM) with burst indicator, dynamic Accuracy health glow (Emerald >97%, Amber 90-96%, Rose <90%), Error counter, and Elapsed time.
   Smooth Gliding Cursor & Ghost Pace Caret: Sub-pixel animated caret with real-time target pace pacing across the text.
   Sleek Mechanical Keyboard Guide: Custom low-profile keycaps with tactile press bounce and glowing next-key indicator.
   Master & Blind Modes: Instant failure penalty on typo in Master Mode; progressive blur and tactile focus in Blind Mode.
3. 🧠 Procedural Pseudo-Word Adaptive Engine
   N-Gram Synthesizer: Replaced static word patterns with dynamically synthesized, phonetically plausible drill words targeting specific transition bottlenecks (slow_transitions) and weak keys.
4. ⌨️ Global Command Palette (Ctrl+K / Cmd+K)
   Keyboard-First Spotlight: Quick fuzzy jump to any lesson, mode, theme toggle, or drill without leaving the keyboard.
5. 🛡️ In-App Obsidian Glass Exit Modal & Native Cleanup
   Replaced the clunky Windows OS message box with a custom glass in-app confirmation modal and clean desktop window destruction.
6. 🔧 SQLite Foreign Key Resiliency & Web Audio Engine
   Fixed foreign key constraints in save_session to seamlessly support adaptive micro-drills and custom practice sets (lesson_id: NULL).
   Built-in zero-dependency Web Audio synthesizer providing synthesized mechanical switch clicks, soft studio tones, and rhythmic metronome pulses.
