Clustering Algorithm

1. Extract Seed Topics: Identify main themes from expanded list
2. Group by Semantic Similarity: Keywords with overlapping meaning
3. Map Intent: Assign I/C/T/N to each cluster
4. Identify Pillar: Highest-volume, broadest term = pillar
5. Map Supporting: Lower-volume terms support pillar
