+    REWRITTEN 2026-09-17 AFTER THE MEASUREMENT CONTRADICTED THE FIRST VERSION.
+    That version said theta_star is biased low by 10**(-0.2*grey) -- 0.766x on
+    event 194 -- straight from the CSB relation.  The ab194/av_true arm, the
+    first run with the colour-anchored prior, measured theta_star at 0.983x of
+    truth.  So the arithmetic was right about the CSB relation and wrong about
+    where the residual lands: theta_star is PROTECTED, because the light curve
+    pins rho * theta_E independently of the SED.  What actually absorbs the
+    grey term is teffsed, and behind it the (R_source, D_source) pair.
