Horsemen Index — How bubbly are we? = I + II + III + IV (max 400). Equal-weight Lamont-hybrid; no fancy composite. Chart overall series plots Σ÷4 on the shared 0–100 axis beside the four dials. III′ (issuanceWithoutMegas) charts the non-mega track so SpaceX·Anthropic·OpenAI/≥$10B megas cannot fully hijack the main III dial. Editorial judgment—not a vendor index.
