`virtualPages` generates Eleventy pages from a `pages.yaml` file in the input directory. Each entry's front-matter data is passed directly to `addTemplate`; if the entry has a `permalink` field it is used to derive the virtual slug (e.g. `permalink: /about/` → `.about/index.md`), otherwise the array index is used.
