/* Shared by the homeowner cost guides (*-cost-calculator.html) and the fitter articles (prices-on-your-website.html,
   price-calculator-for-your-website.html).
   The calm look (Tom, Sun 4 Oct 2026): the homepage's layout without its motion, as on the dashboard. Page --ground,
   cards --paper, type and buttons --ink, secondary text --ink-2. Tape yellow is the mark and the one button on the
   fitters panel; teal is for links only. Colours, type, spacing and radius all come from tokens.css; no colours are
   declared here. Fonts: Big Shoulders Display (the mark only), Public Sans (text) and DM Mono (numbers only). */
