+This repository adheres to the

+standard: normalized scripts in `script/` are the entrypoints for the
+development workflow, and the Makefile targets are thin shims that call them. We
+provide:

+- `script/projectname` — output the project name (our own extension); used by
+  `script/docker` for the image tag
+- `script/test` — run the test suite (no tests defined here)
+- `script/lint` — lint the markdown files with prettier
+- `script/fmt` — format all markdown files with prettier (writes)
+- `script/fmt-check` — check formatting (read-only)
+- `script/check` — run all checks: `test`, `lint`, `fmt-check` (our own
+  extension)
+- `script/docker` — build the Docker image, tagged via `script/projectname`
+  (byte-identical across repos)
+- `script/cibuild` — cd to the repo root and `docker build .` (what CI runs; the

+- Repos follow the
+  [Scripts to Rule Them All](https://github.com/github/scripts-to-rule-them-all)
+  pattern: the implementation of each Makefile target lives in an executable
+  script in `script/` (`script/test`, `script/lint`, `script/fmt`,

+  are thin shims that call them. `script/cibuild` (a standard
+  scripts-to-rule-them-all name) runs the CI build: it changes to the repo root
+  and runs `docker build .`; the Gitea workflow calls it. Four further scripts
+  are our own extensions to the standard: `script/check` runs `script/test`,
+  `script/lint`, and `script/fmt-check`; `script/precommit` is what the git

+  installs the git pre-commit hook (the `make hooks` target shims to it); and
+  `script/projectname` (literally that filename) simply outputs the project's
+  name. Scripts that need the name call `script/projectname` — e.g.
+  `script/docker` assembles its image tag from it — so those scripts stay
+  byte-identical across all repos. Repo-type-specific pre-commit extras (e.g.
+  `go mod tidy` verification in Go repos) belong in `script/precommit`, not in
