/*
 * doric.css — Unified Doric theme (light + dark)
 * Works with: topics, trees, and org-parse
 *
 * Adapted from Protesilaos Stavrou's doric-themes for GNU Emacs
 * https://github.com/protesilaos/doric-themes
 * Light mode: doric-light — cool, monochromatic, white background
 * Dark mode:  doric-dark  — cool purple-tinted black background
 *
 * "Doric Only Really Intensifies Conservatively"
 *
 * Few colours. Nearly monochromatic in many contexts.
 * Typography and subtle grey gradients establish the visual rhythm.
 *
 * Supports dark mode via:
 *   - prefers-color-scheme (topics, trees, org-parse)
 *   - [data-theme=dark] attribute
