Theme Name: Centavo AI
Theme URI: https://centavo.ai
Description: Brand child theme for centavo.ai — a futuristic AI-news publication. Child of the first-party PBN Base theme. Distinct identity: a dark "space" canvas with neon violet→cyan gradient accents, a soft glow on the masthead, gradient-edged glassy cards, system-ui display headings paired with a monospace meta voice and a faint dotted-grid motif. Tech-forward and luminous — unrelated to the network's betting brands. No third-party CSS/JS, no build step, system fonts only.
Author: PBN
Template: centavo-base
