 * Brand canon: dark-dominant marketing surface (per brand-visual.md).
 * Italic uppercase display headline (Host Grotesk Italic stands in for the
 * canonical HiFy Rounded Italic — to be upgraded to the real face in v1.1
 * once the WOFF2 is bundleable; tracked in BIZ-1154).
 * Brand gradient is rare and earned — used once, on the CTA.
 * Asymmetric left-aligned layout. Confetti graphics deliberately omitted —
 * a utility page doesn't need them.
 *
 * Sizing/spacing/font: rem and clamp(), per shared/references/code-rules.md.
 * Only px usage is borders, hairlines, and pattern-internal hairlines.
