 Ctrl-C stops development. This website needs no runtime credentials or credential `.env` file.
+
+For contributor verification, prepare the pinned helper source before running native tasks:
+
+```sh
+git clone https://github.com/nicodes/tools.git .ci-tools
+git -C .ci-tools checkout --detach f7e243524ce2aa29f299e4c79db33001f72f4a30
+mise install
+mise run check
+```
+
+Build commands record source and exact regular output hashes. Declared tests produce evidence from the current verification session in `.artifacts/verification`.
