**TLDR:** Module 9 capstone: implement Llama-3 compatible RoPE in 50 lines pure NumPy. cos/sin cache precomputation, pair-wise rotation, position visualization (cos/sin heatmap, attention bias pattern). Compatibility test with actual Llama-3 weights. Turkish examples for position pattern interpretation.
