+HONEST LME (per-animal random slope, day|rat): interaction F(1,7.1)=6.49, p=0.0379
+  (Satterthwaite DF ~= residual on this random-intercept model; the random-slope
+   model above is the honest learning-rate test -- DF collapses toward the animal count.)
+INTERPRETATION: stim x day interaction SIGNIFICANT positive -- treatment improves FASTER (benefit accumulates) (p=0.003127, slope diff=+0.04902)
+Paper (N=24, count): interaction t(227)=2.68, F(1)=7.12, p=0.008.
