Tree-Level Matching Theorem -/ 146 147/-- The decisive structural matching theorem: if the RS amplitude and 148 phase space for a channel equal their SM counterparts, then the RS 149 partial width equals the SM partial width. 150 151 The hypothesis is exactly the content of "RS reproduces the SM tree 152 amplitude in this channel." In practice this hypothesis is satisfied 153 once the canonical-normalisation map of `HiggsEFTBridge` and the 154 Yukawa map of `HiggsYukawaBridge` are closed for the channel of 155 interest. -/
