/*
 * sauerland.tech: the one stylesheet of the site.
 *
 * Tokens and components follow the lenne.Tech dark look of the meetup images
 * (render_meetup_images.py in the lt-marketing plugin): paper ground, dot grid,
 * orange glow, the rotated highlight box, JetBrains Mono labels.
 *
 * The page runs under `style-src 'self'`, so every style lives here: no style
 * attributes and no <style> elements in the HTML, also not inside inline SVG.
 * The asset placeholders in the url() values below are replaced by build.py
 * with the fingerprinted file names.
 *
 * Contrast (WCAG 2.2 AA), measured: ink 18:1, soft 13:1, muted 8.3:1 and
 * orange 8:1 on paper; paper text on the orange button 8:1; input borders
 * 4.2:1 against the card (non-text minimum 3:1).
