Pennington.Book.BookArtifactService

namespace Pennington.Book;

/// Single source of truth for every book artifact, behind the artifact-tier façade BookArtifactContentService (which serves dev requests and enumerates the PDFs for the static build) — the same shape as SearchArtifactService. The projection fold (post-pipeline HTML per page) and the static-asset map are computed once, lazily; each book's composed HTML is cached per (book, locale); PDF bytes are rendered on demand through the singleton ChromiumBrowserProvider and cached until a file change drops the whole service. EnumerateArtifacts is deliberately cheap — pure options × locales, no projection, no Chromium — so build enumeration and link verification never trigger a render.
