⚡ Bolt: Optimize getVisibleSections mapping - #750
Conversation
💡 What: Refactored `getVisibleSections` to replace chained `.map()` and `.filter()` array methods with a single nested `for...of` loop. 🎯 Why: When deriving multiple separate data structures (like maps and filters), multiple full-array iterations were occurring, allocating multiple intermediate arrays. 📊 Impact: Reduces O(N) memory allocations and GC pressure, providing O(1) memory overhead for rendering the info sheet. 🔬 Measurement: Can verify the UI renders the sections exactly as before while observing reduced memory allocation in profiling tools.

Pull request overview
This PR refactors getVisibleSections in TourismInfoSheet to avoid chained map()/filter() calls by using a single nested for...of loop, aiming to reduce intermediate allocations during section derivation.
Changes:
- Replaced chained
map()/filter()transformations with an imperative loop to build visible sections/items in one pass. - Normalized and filtered item values inline while constructing the resulting section list.
