No build step, on purpose
A studio site I alone maintain, and will still be editing years from now between client projects.
Hand-written HTML, CSS and JavaScript with no bundler and no framework. What is in the repository is exactly what the browser runs.
No module system and no type checking, so structure has to be enforced by discipline rather than by a compiler. In exchange there is no dependency graph to rot — nothing to reinstall, nothing to migrate, and no build that breaks because a transitive dependency shifted.
