- Replaced `Array.from({ length: N }).map(...)` with `Array.from({ length: N }, ...)` in App.tsx and Workspace.tsx
- Optimized `section.roles.filter().map()` to use `.reduce()` in SectionRoadmap.tsx to bypass creating an intermediate array.

💡 What: Optimized Array mapping methods that were inadvertently creating intermediate arrays during renders. Replaced
Array.from().map(...)withArray.from({ length }, mappingFn)and chained.filter().map()with.reduce().🎯 Why: Avoiding intermediate array creation reduces the memory footprint and lightens Garbage Collection (GC) overhead during frequent React render cycles.
📊 Impact: Zero GC allocations for intermediate arrays during full page redraws across App.tsx, Workspace.tsx, and SectionRoadmap.tsx.
🔬 Measurement: Verified the optimization by confirming all unit tests run exactly the same and running
