What the standard puts in

A generated project holds more than the code that runs. Everything else in it is there because leaving it out costs more later.

The files

File	Why it is there
.github/workflows/ci.yml	The gate, running exactly what pnpm lint runs locally
cliff.toml, CHANGELOG.md	The changelog is generated from the history, so the history has to be worth generating from
docs/adr/	Decisions outlive the conversation that produced them
.editorconfig	Indentation stops being a matter of whose editor opened the file
.gitattributes	eol=lf, so a tool that rewrites a file to CRLF cannot hide the real change in the diff
components.json	shadcn add knows where to copy a dowel primitive
lyrn.toml	What this was generated from, and whether it has a mark yet, for doctor and upgrade later

The gate is one script

pnpm lint is eslint, then tsc --noEmit, then the tests. CI runs that same script rather than its own sequence, so there is no way for the two to drift apart and no way to be surprised by CI.

The first commit

lyrn does not leave an uncommitted directory behind. The project starts as a repository on main with one Conventional Commit, because the changelog config it ships with reads Conventional Commits — a history that starts messy cannot be tidied retroactively.

Colour goes through the theme

A component names a token and never writes a colour down, which is what lets the theme swap it underneath and the product’s accent move. eslint enforces it via dowel/no-raw-color, so it is a rule rather than a habit.
