/* MadHat Consulting — site layer (madhat-consulting.com).
   Load order matters: /styles/styles.css (the Industry design system) FIRST,
   then this file.

   Section 1 is the dark-theme override carried verbatim from the design doc
   ("MadHat Site.dc.html", helmet <style>) so shipped pages match the
   artboards pixel-for-pixel. Do not retune it here — it is the design's.

   Section 2 promotes the artboards' structural inline styles (grids, page
   paddings, hairline rules) to classes, keeping the exact artboard values,
   so the responsive layer in section 3 can reach them. One-off typography
   stays inline in the HTML, exactly as the artboards wrote it.

   Section 3 is the v1 responsive layer: the artboards are fixed 1280px;
   this collapses the multi-column grids and scales the hero type without
   redesigning anything. */
