during the high-frequency render loop.

💡 What: Replaced
Paragraph::new(" ".repeat(inner.width as usize))withBlock::default()in thedraw_chassisrender function insrc/ui/mod.rs.🎯 Why: In Ratatui TUI render loops, repeatedly dynamically constructing strings of spaces to paint background colors creates expensive string heap allocations per scanline on every frame. Applying the background style to an empty
Blockachieves the exact same visual result with zero allocations.📊 Impact: Eliminates per-scanline string heap allocations during the high-frequency frame render loop when drawing the chassis background. Reduces memory fragmentation and GC/allocator pressure.
🔬 Measurement: Verify that UI layout and background colors remain completely unaffected while tracing allocations (e.g., via profiler or valgrind) reveals fewer String allocations per render cycle.
