 The library is optimized for high-load scenarios. Key benchmarks show significant performance gains (performance could be differ due to 1. different CPU architectures 2. statistics):
 
-Formatting (Format) vs fmt.Sprintf: 3-5x faster for complex templates.
+Formatting (Format) vs `fmt.Sprintf`: `3-5x` faster for complex templates.
 Slices (SliceToString) vs manual fmt-based joining: from `2.5` faster up to 20 items.
