⚡️ Two Regimes of Git Every Developer Should Know
Git looks simple until you realize there are two entirely different ways to use it. 'Tactical Git' drives daily commits, merges, and rebases; 'CI Git' underpins automated pipelines and reproducible builds. Mixing the two mindsets is where chaos begins — understanding the split is key to mastering real-world version control.
