/**
 * eratic.ro reads the other three sites straight off disk.
 *
 * No API, no build-order dependency, no duplicated copy: the home page globs
 * the same Markdown files blog, fav and io build from, so it cannot show
 * something that is not published or miss something that is.
 *
 * The schemas here are deliberately a subset — title, summary, date and the
 * one or two fields needed for a label. Zod strips anything it does not
 * declare, which is what makes this safe: `cover` and `photos` reference image
 * files by paths relative to *their* site, and trying to resolve those from
 * this project would be a build error. Not declaring them means they are
 * dropped before anything can try.
