+# if you are used to ignore files, be aware that .typstignore is a bit more limited:
+# - only this file is used; .typstignore files in subdirectories are not considered
+# - patterns must match file/directory names from the beginning: `x.typ` will not match `src/x.typ`
+# - `*` in patterns works, but also matches directory separators: `*.typ` _will_ match `src/x.typ`
+# .git and .typstignore are excluded automatically
