Theme Name: Studio Portfolio
Theme URI: https://example.com/studio-portfolio
Author: Built with Claude
Description: A clean, minimal portfolio theme for photographers and designers. Fixed paper sidebar with a menu grouped by section, and a full-height gallery with edge navigation. Projects are managed entirely from the WordPress admin. Typography and colours are chosen with dyslexia-friendly reading in mind (soft off-white surfaces instead of harsh white, softened near-black ink, and the Lexend typeface).
