/* =========================================================================
   How to buy ("Ways to buy"): template-ways-to-buy.php (/how-to-buy/).
   Scoped to .hb, mobile first, min-width media queries only (640 / 768 /
   900 / 1200). The house recipe from the 18 Sep 2026 spec
   (docs/superpowers/specs/2026-09-18-support-and-content-pages-design.md),
   plus what this page needs. The enquiry form is styled by css/product.css
   through the .pd .pd-enquiry reuse.

   Bands: navy hero, white route cards, then the grey enquiry band above the
   navy footer. A sibling of the contact page, so it uses the same plain navy
   hero rather than a photograph.
