/* My Duuka - website theme.
 *
 * Deliberately restrained: one accent colour, generous whitespace, few borders, no gradients
 * except where they carry the brand. The product being sold is calm and legible, and a loud
 * marketing site would contradict it.
 *
 * Palette matches the app exactly (mobile/tailwind.config.js and the logo kit), so the site and
 * the first screen of the app feel like one product.
