/* Task page styling.
 *
 * Matches the Emulate marketing site (dewey-site: app/globals.css .dark theme):
 * same near-black surface, the same Emilio display font for titles and Host
 * Grotesk for body, and the same teal→indigo brand gradient. A viewer who
 * follows a share link and someone browsing emulate.com should feel like they
 * are in one product — the share page is hosted under the site's own domain.
 *
 * Token values are duplicated rather than imported: this page is deliberately
 * no-build, dependency-free JS/CSS so a share link never waits on a bundler.
 * Fonts are served self-contained from /task/fonts. If the site's tokens
 * change, mirror the .dark values here.
