Horizontal bar chart showing variance decomposition results (η² from ANOVA).

Two horizontal bars:
1. "Reflection Style" (green bar): 36.2% of variance explained (η²)
   Range: [34.7%, 37.7%]
2. "Provider Identity" (orange bar): 5.6% of variance explained (η²)
   Range: [5.1%, 6.1%]

Yellow annotation box shows "6.4× ratio" indicating style explains ~6.5× more variance.
Both effects validated via permutation testing (1000 permutations, p < 0.001).

Caption in blue: "η² from ANOVA on 2D UMAP coordinates. Style explains 6.5× more variance than Provider."

Key finding: How you prompt reflection matters more than which model you use.
