/*
 * The gate in Knowit's visual identity ("Nordic Skies", Visual Identity Guidelines 2024), dark theme.
 *
 *  - Colour: Knowit Black #0B0B26 as the ground, Knowit White #FEFBE6 for text (never pure black or white), Purple
 *    #CFCEFF and Blue #372BC5 as the primary colours, Peach and Green from the extended palette. #9795FF is the
 *    purple of the web UI colour kit, used for highlighted words and links on dark. Text and colour pairs follow the
 *    book's accessible combinations: white on black, black on purple, white on blue.
 *  - Type: Bagoss, Regular only; Arial is the brand's web fallback. Hierarchy comes from size contrast, body text
 *    stays under 724 px wide.
 *  - Shapes: "windows" (circle, rounded square with a 32 px radius, arch) for containers; the Knowit star only as
 *    a bullet; gradients are the supplied pastel image and never sit under text.
 *  - No inline styles anywhere: the CSP allows own files only.
