/* ============================================================================
   The RealReal × Kaufman Rossin — RR-02 theme (luxury-editorial, from scratch).
   Grounded in the RealReal brand: near-black ink on warm paper, high-contrast
   didone display + neutral grotesk body, hairline rules and generous whitespace
   as the structural motif (replacing the Atlantis "bubbles"). No chalkboard.
   The vibe is treatment, not novelty fonts — web-safe stacks only, so the strict
   CSP (font-src 'self') is untouched.
