   Claudia Platinetti — one-page portfolio
   OWN-WORLD: warm ink-white ground, near-black type, antique gold as the
   signature accent (foil, framing, dividers), forest green + dusty rose as
   quiet botanical accents pulled straight from the artist's own logo mark.
   Display: Bodoni Moda (fashion-editorial serif, her Versace/CK/Tod's
   background earns it). Body/UI: Archivo (quiet grotesk, gets out of the way).
