/* Civetta marketing site — single hand-rolled stylesheet.
 * No frameworks. No JavaScript. No external assets except Inter from
 * Google Fonts (preconnected so first-paint isn't blocked).
 *
 * Color tokens roughly mirror the slate palette used by the
 * authenticated web dashboard's LegalPageShell, so a reviewer
 * navigating between the two doesn't see a jarring style break.
