BGE embeddings occupy a narrow cone in vector space, so raw cosine of two unrelated words already sits at ~0.40-0.55. Displaying `raw * 100` made every random guess read as 40-70% warm, which defeated the warmth UX. format.js now applies a normalized sigmoid (FLOOR 0.40, CENTER 0.60, SCALE 8) to remap raw cosine → displayed 0-100. Unrelated pairs drop to ≤30, loose relation lands around 40-55, clear synonyms hit 85+, and exact match stays at 100. Emoji buckets were rebased onto the calibrated score; formatWarmth lost its sign column (calibrated output is always non-negative). render.js rounds once and feeds the integer to both formatWarmth and warmthEmoji so the display value and bucket stay in sync. Constants are empirical — retune if swapping to a non-BGE model.
