/* Deliberately plain.
 *
 * The visual direction is not settled yet — Palantir/Vercel/Linear are still being weighed — and
 * the one decision already made is that this must NOT look like adlathe. Several certification
 * sites sharing one visual language read as a single template applied repeatedly, which is worse
 * for a portfolio than five plainly different builds.
 *
 * So this is typographic and neutral: readable, honest, and cheap to throw away. It is a holding
 * page, not a design statement. Light by default, because adlathe is dark. */
