What I delivered

• Screen-level optimisation: removed a 40 to 50 % frame rate drop, reaching a steady 120 fps with no stutter.
• Tab navigation: fully eliminated the switch freeze that cost up to 30 % of the frame rate.
• Rebuilt the lists on Legend List: fast scrolling stays smooth and screen load times dropped sharply.
• CPU usage down 40 % and memory footprint down 20 %, alongside an atomic redesign of the component tree.
