TypeScript lives in source/, CSS lives in styles/, both as peers at the repo root. The @css alias in package.json maps imports like @css/views/shrinkage-calculator.css to the styles directory. Each tool lives in source/views/ as a directory of Mithril components with a shared state.ts for the model layer. Reusable primitives live in source/components/. Routes are wired in source/index.ts via m.route; see docs/notes.md for project-wide design notes and docs/<tool-name>/ for per-tool reference material.
