radii for two systems that inhabit particularly underpopulated regions of mass-radius-period space: KIC 2445134 and KIC 3003991. Our joint spectrosopic and photometric analysis of KIC 2445134 (${\ensuremath{\mathit{q}}}{}=0.411\pm0.001$) yields masses and radii of ${\ensuremath{\mathit{M}_A}}{}=1.29\pm0.03{\ensuremath{\mathit{\,M_\odot}}}$, ${\ensuremath{\mathit{M}_B}}{}=0.53\pm0.01{\ensuremath{\mathit{\,M_\odot}}}$, ${\ensuremath{\mathit{R}_A}}{}=1.42\pm0.01{\ensuremath{\mathit{\,R_\odot}}}$, ${\ensuremath{\mathit{R}_B}}{}=0.510\pm0.004{\ensuremath{\mathit{\,R_\odot}}}$, and a temperature ratio of $T_B/T_A=0.635\pm0.001$; our analysis of KIC 3003991 (${\ensuremath{\mathit{q}}}{}=0.298\pm0.006$) yields ${\ensuremath{\mathit{M}_A}}{}=0.74\pm0.04{\ensuremath{\mathit{\,M_\odot}}}$, ${\ensuremath{\mathit{M}_B}}{}=0.222\pm0.007{\ensuremath{\mathit{\,M_\odot}}}$, ${\ensuremath{\mathit{R}_A}}{}=0.84\pm0.01{\ensuremath{\mathit{\,R_\odot}}}$, ${\ensuremath{\mathit{R}_B}}{}=0.250\pm0.004{\ensuremath{\mathit{\,R_\odot}}}$, and a temperature ratio of $T_B/T_A=0.662\pm0.001$.'

Introduction
============

Eclipsing binaries (EBs) have served as benchmarks for stellar astrophysics for hundreds of years [e.g., @1783RSPT...73..474G]. Advances in radial velocity (RV) measurement precision over the past several decades have steadily improved the precision of masses derived from EBs. Compilations of EBs show that the total number, diversity, and measurement precisions of detached, main-sequence EBs have steadily increased: 72 stars with masses and radii ($M$, $R$) measured to $<$ 15% in , 88 stars with $M$, $R$ $<$ 2% in , 188 stars with $M$,
