CSS Cascade Layers replace team negotiation over style conflicts, not just specificity

A deep-dive analysis argues that CSS Cascade Layers solve a social problem in frontend development, not merely a technical one. Before their introduction, resolving style conflicts in large teams relied on informal agreements, tribal knowledge, and key individuals remembering unwritten rules. As teams grew or changed, this negotiation-based system broke down, with CSS specificity becoming the battlefield for unresolved ownership disputes. Cascade Layers replace this with a single, explicit declaration that the browser enforces consistently, requiring no further discussion or memory. The order of precedence becomes versioned source code visible to every contributor, regardless of when they joined the project.
