/* The PLATFORM SITE's stylesheet — witbitz.chat/, /spaces, /agents, /trust, /access.
 *
 * Deliberately separate from styles.css: that one is still worn by the older storefront pages
 * (privacy, terms, admin) and by witz, so restyling it in place would drag them along. This is also
 * NOT a third look — it is the design system already used by the docs portal (portal/index.html),
 * brought to the product site, which until now was plainly the worse-looking of the two.
 *
 * Tokens, type scale, eyebrow, button and the architecture figure are ported from the portal so the two
 * surfaces read as one product. Dark mode included: the portal has it, so the site should too.
