/*
 * Volta landing site.
 * Every colour, radius, spacing step, shadow and type size comes from the design tokens of the user app
 * (GitLab volta/web, branch dev, src/theme.ts): lightColors for the page body, darkColors (Volta's
 * default theme) for the header, the heroes, the call to action and the footer; the yellow gradient is
 * the logo's own (src/components/ui/Logo.tsx).
