/*
 * Intelli-Accounting marketing site.
 *
 * Colours are the brand tokens (branding/brand-tokens.css) — cream ledger paper, steel blue,
 * brick — kept in sync by hand because this page ships without a build step. One stylesheet, no
 * framework, no external requests: the page holds nothing that would need a cookie banner, and it
 * loads on a bad connection in a Karoo dorp, which is the actual audience.
 *
 * Dark mode follows the reader's own setting. In the product itself the dark theme is a paid
 * entitlement; on a public page that would be silly, so it is simply respected here.
