Theme Name:   Graph Lines
Theme URI:    https://graphlines.com/
Description:  Accessible child theme for Astra, made for graphlines.com, the free printable graph paper generator. Atkinson Hyperlegible Next and JetBrains Mono are self-hosted, so pages make no requests to Google. Colours meet WCAG 2.2 AA, with a dark scheme that follows the visitor's system setting, visible focus rings, forced-colours support and reduced motion. Includes block patterns, block styles and page content for the Graph Lines site.
