/**
 * Single source of truth for blog author metadata.
 *
 * Ported from the old Docusaurus `blog/authors.yml`. Keeping this as a
 * typed TS module (instead of YAML) means:
 *   - Every entry is compile-time checked to have all required fields
 *     (via `satisfies Record<string, Author>`).
 *   - `AuthorId` is a literal union (`"penguine" | "kritinv" | ...`) so
 *     Zod can use `z.enum(AUTHOR_IDS)` to validate frontmatter at build
 *     time — a typo in a post's `authors: [...]` array fails the build
 *     with a path like `content/blog/foo.mdx: authors[0]`.
 *   - `getAuthor(id)` returns a fully-typed `Author` with no casts.
