/**
 * DESIGN PLAN (see also frontend-design skill notes in the build log)
 * ---------------------------------------------------------------------
 * Signature element: the hero's "verified profile card" — styled like an
 * official ID/certificate, gold corner brackets, monospace field rows.
 * Grounded in the actual product (verified profiles) and SA context
 * (ID books, certified documents are a familiar visual language).
 *
 * Type: Georgia for display headlines (serif, authoritative, zero
 * external font dependency). System sans for body (--gh-font, base.css).
 * Monospace for "form field code" eyebrows/labels — reinforces the
 * official-document motif used sparingly throughout, not just the hero.
 *
 * Numbered "How it works" steps are earned here — genuinely sequential
 * content — styled as STEP 01 in monospace rather than generic circles.
