Release Notes — Version 2.2.0 (Updated: September 3, 2026)

1. Edge-to-Edge Inside-Line Sliding Infotainment Banner

• Full-Width Horizon Viewport: Replaced the narrow floating card with a full-width header banner spanning the entire center TFT display edge-to-edge.
• Inside-Line Emergence & Retraction: Emerges smoothly from inside the upper TFT dividing line (Easing.OutCubic, 420ms) upon track change or source selection, and retracts back inside the upper line (Easing.InOutCubic, 350ms) after a 5-second hold.
• Live 4-Bar Audio Spectrum Visualizer: Dynamic audio equalizer bars animate in real time alongside playback status.
• Continuous Marquee Typography: Auto-scrolls long track and artist names with hold-at-edge smoothing.

2. High-Density Compact ECU Diagnostic Test Bench

• Space-Efficient Ergonomic Footprint: Compact 215px card height with 20–24px precision buttons and slim sliders, fitting cleanly into smaller desktop windows without excessive scrolling.
• Elimination of Raw Consumer Emojis: Replaced all basic Unicode emojis with hardware-grade glowing micro-LEDs (#00E676 emerald, #FF3D57 red, #00E5FF cyan, #FFA000 amber) and a pulsing top test bench status heartbeat.
• Tactile Interactive Micro-Feedback: Every control features smooth scale-down press animations (scale: pressed ? 0.96 : 1.0) and subtle hover border glows.
• Subsystem Engineering Categorization:
  • SYS-01: Powertrain & Engine (Cluster state machine, live speed/RPM sliders, quick speed sweeps: 0, 40, 80, 120 km/h, autonomous drive demo).
  • SYS-02: Transmission & AMT Gearbox (PRND selector, D1..D5 and M1..M5 ratios, fluid sliders, cruise control bar).
  • SYS-03: Steering D-Pad & Trip HMI (Steering wheel physical D-Pad cluster, trip sub-pages, trip reset).
  • SYS-04: Chassis, Braking & TPMS (Electric parking brake toggle, individual FL/FR/RL/RR tyre PSI readouts, puncture simulation, EPS power steering fault trigger).
  • SYS-05: Access & Body Closures (4-door ajar matrix, hood, trunk, sunroof alert, bulk secure/ajar presets).
  • SYS-06: Occupant Restraints (Driver seatbelt, 3-point rear passenger occupancy matrix with silent buckle preset).

3. Automotive Green Neutral Gear ("N")

• Dedicated Distinctive Neutral Display: When the transmission is in "N" (Neutral), the gear text illuminates in vivid automotive green (#00E676) on both the top cruise gear indicator and the central transmission block. All other gears (P, R, D, D1..D5, M1..M5) remain pure crisp white (#FFFFFF).

4. AIS-145 3-Point Rear Seatbelt Occupant Grid & Standard Beeping

• 3-Seat Occupant Sensor Matrix: Dedicated sensors for Rear-Left (RL), Rear-Center (RC), and Rear-Right (RR).
