/* wohngeld-rechner.info – "Das Haushaltsbuch" (design/DESIGN.md): paper, Königsblau ink, one highlighter.
   Every colour, size and space is a token on :root, light and dark; body text is 7:1 or better
   everywhere (measured: design/tools/contrast.py). The class names are the templates' own (header.php,
   footer.php, template-parts/entry.php, functions.php); the explainer kit and each calculator module
   style only their own (.wgr-kit-…, .wgr-<module>). Phone first: nothing under 15 px, nothing sideways. */
