Atoms, layers, types, tokens: a new CSS methodology built on CSS Modules

It's not like I dislike Tailwind, but I can't say that I'm in love with it either. I'm keen on the "atomic CSS" part of it, but reading all this mass of short class names in the HTML is a bit of a hard job, don't you find? Especially when it comes from an AI model and the diff is really big. Also, I've noticed that models feel free to use anything Tailwind offers, and it's hard to harness them properly. That was the reason I decided to look for another way to write CSS: one that gives me flexibility, sets clear architectural boundaries for how styles are organized and composed, and is easy to read and maintain. I chose CSS Modules because it can be harnessed and checked very well. The authoring remains ordinary CSS, plus the composes extension when a project composes on the CSS side, so every diff is plain CSS you can compare line by line. The great part: you can easily debug it. You know, browser DevTools are really good for that. So, my claim upfront: once the project plumbing exists, a small set of conventions on top of CSS Modules gives you a compact workflow for common component styling: a shared style API, typed variants, observable state, deterministic local overrides, and semantic color theming. It also gives you readable diffs, useful names in DevTools, and compile-time errors instead of a silent undefined in the class string. What I'm proposing here is a new CSS methodology. A young one, to be honest: this article is its first full write-up, a beginning rather than a finished spec. But it's aiming for the same shelf where BEM, OOCSS, SMACSS, and others sit, and every system on that shelf started the same way: as somebody's blog post or conference talk. Mine proposes an architecture too, down to how a single module file is laid out. I respect all of them, but they were invented before components, and most of their rules exist to solve one big problem: scoping styles through naming discipline. CSS Modules already scopes styles mechanically, so all that disci
