◆ The PatternSelectively focusing on relevant parts of the input
Each token asks: "which other tokens are most relevant to me?" via dot-product similarity between queries and keys.
Attention(Q,K,V) = softmax(QKᵀ / √d) · V
Q = Query | K = Key | V = Value | √d = scaling to prevent saturation

Multi-Head Attention: Run h attention functions in parallel, each with different learned projections. Allows attending to syntax, semantics, and coreference simultaneously.
Pattern bridge: Selectively weighting inputs by relevance appears in VWAP (volume-weighted attention to price) and transformer self-attention.
