/*
 * beratungspraxis-oldenburg.de -- plain CSS, no build step.

 * Colours, fonts and spacing live in the :root block below. Everything else
 * derives from those variables, so changing --accent recolours buttons,
 * links, list markers, hover states and tints in one go.
 *
 * The Caddyfile sends a strict Content-Security-Policy, and collectstatic
 * would try to rewrite any file reference in here:
 *   - this file must not load anything (no url-functions, imports, font-face)
 *   - no style="" or <style> in the HTML; add a class here instead
 *
 * The favicons (favicon.svg/.ico, apple-touch-icon.png) have the accent
 * baked in and do not follow a change here.
