When Your Makefile Is Ruined

The silent killer of build systems: auto-detected indentation. One developer uses tabs, another uses spaces, and suddenly your Makefile implodes because it requires exact tab characters for rules. The editor helpfully "fixed" your indentation and now your CI pipeline is a burning building behind you while you smile, knowing exactly who to blame. Nothing says "welcome to dependency hell" like watching four months of work collapse because someone's IDE thought it knew better than GNU Make's 1976 tab requirement.
