  "abstract": "Using DFPT and Wannier-interpolated matrix elements in EPW, we find that isotropic tensile strain of 0--6\\% narrows the B:2$p$/C:2$p$ bands at the Fermi level while softening the phonon branches most strongly coupled to them, driving the coupling constant $λ$ from 0.967 to 2.620. All four strained configurations remain mechanically and dynamically stable, satisfying the Born--Huang criteria with no imaginary phonon modes at any strain level. The fully anisotropic Migdal--Eliashberg equations give a $T_c$ that rises monotonically from 53.5~K to 84.5~K across the strain series, crossing the liquid-nitrogen boiling point at 6\\% strain. The SISSO-based machine-learning model in EPW agrees with the anisotropic Migdal--Eliashberg $T_c$ values to within 10~K across the strain series.",
