/* Rally Suite marketing site.
 *
 * The look follows rally-suite-pitch: sans-serif headings over a serif body,
 * generous measure, no ornament. It should read like a serious document, not a
 * SaaS landing page — the audience is buying operational infrastructure for an
 * organization, and the pitch earns trust by looking considered rather than sold.
 *
 * The accent is deliberately neither red nor blue. Both are partisan-coded in US
 * politics, and Rally Suite serves organizations across the spectrum.
 *
 * Fonts are system stacks on purpose: no third-party request, nothing to load,
 * nothing to leak.
