Create a minimalist black-and-white vector avatar logo of a mythic anime
woman shown in elegant side profile facing right, cropped from the chest
up on a plain white background. Give her long flowing {argument
name="hair color" default="black"} hair with bold white highlight
streaks and smooth graphic shapes, rendered as high-contrast ink
silhouette art with clean sharp edges. She wears a winged headpiece
reminiscent of Hermes or a messenger god helmet, with one large white
feathered wing visible on the side of her head and a circular metallic
earpiece detail. Dress her in a sleek high-collar garment with a luxury-
fashion feel, and hang a prominent pendant or zipper pull shaped like
the letter {argument name="monogram letter" default="H"} at the center
of the collar. The face is intentionally obscured by a centered soft
gray rectangular blur block covering most facial features, creating a
censored anonymous profile-image effect. Overall style: luxury brand
avatar, fashion logo, anime-inspired goddess silhouette, monochrome
vector emblem, smooth negative-space highlights, balanced composition,
modern and iconic, suitable for a social media profile picture.
