/* Rubberduck Me — the whole site's styles.
 *
 * The Content-Security-Policy served by CloudFront is `style-src 'self'`, which
 * blocks inline <style> blocks and style="" attributes alike. Everything has to
 * live here, and the pages ship no JavaScript at all. Keep it that way: the CSP
 * is the reason it can be as strict as `default-src 'none'`.
 *
 * Palette is the extension overlay's, so the site and the product look related.
 * Yellow is a fill and border colour only — #ffd93b on white is nowhere near
 * WCAG AA, so it never carries text.
