Massive stars are among the most influential engines in the Universe, shaping their surroundings through radiation, winds, and supernovae driving turbulence, regulating star and planet formation, and seeding the next generations of stars. Their feedback not only sculpts the interstellar medium of galaxies but also sets key boundary conditions for processes that concern nearly every branch of astrophysics: the baryon cycle (an essential ingredient in galaxy evolution across cosmic time), the progenitor environments of gravitational wave sources, the chemical and dynamical histories of planetary
