/*
 * Branchsolve — branchsolve.html.
 *
 * The look of branchsolve.com: off-white paper (#F8F9FF), slate ink headings in
 * Plus Jakarta Sans 800, a deep green primary (#006E2E), white bordered cards,
 * soft green blobs drifting in the hero, mono step numbers, and a dark slate
 * call-to-action band. Colours are read from branchsolve.com. Light only, like
 * the site.
 *
 * Self-contained on purpose: this page does not load css/main.css, so nothing
 * here touches the other apps' pages. The wordmark lives in /branchsolve/img/.
