/* SEO.to — design system. Concept: a bright clear sky. Real sky-blue gradient with soft clouds drifting near the horizon, white cards floating on top with generous radii and soft physical shadows. Optimistic, uncomplicated, human — the internet before everything turned into a moody dark dashboard. Rules: light always, real blue (not slate), white cards, generous roundness, soft shadows with warmth. Diagnostics keep their own signal colours. */ @font-face { font-family: 'Archivo'; font-weight: 400 800; font-style: normal; font-display: swap; src: url('/assets/fonts/archivo-var.woff2') format('woff2-variations'); } @font-face { font-family: 'Plex Mono'; font-weight: 400; font-style: normal; font-display: swap; src: url('/assets/fonts/plexmono-1.woff2') format('woff2'); } @font-face { font-family: 'Plex Mono'; font-weight: 500; font-style: normal; font-display: swap; src: url('/assets/fonts/plexmono-2.woff2') format('woff2'); } :root { --sky-0: #1B77CC; /* deep zenith: 4.6:1 with white, small white type passes AA */ --sky-1: #3E9BE8; --sky-2: #7CC4F2; --sky-3: #C9E9FF; /* horizon haze */ --card: #FFFFFF; --ink: #10263A; --ink-2: #45647F; --ink-3: #5A7490; /* label grey: 4.8:1 on white, passes WCAG AA */ --blue: #0A6FBF; /* link / action blue */ --blue-dk: #075494; --sun: #FFC53D; /* warm highlight */ --pass: #178A4C; --warn: #B06E00; --fail: #C6362B; --sans: 'Archivo', -apple-system, BlinkMacSystemFont, 'Helvetica Neue', Arial, sans-serif; --mono: 'Plex Mono', ui-monospace, 'SF Mono', Menlo, monospace; --r: 18px; --shadow: 0 1px 2px rgba(16,38,58,.08), 0 8px 20px -6px rgba(16,38,58,.18); --shadow-lift: 0 2px 4px rgba(16,38,58,.10), 0 18px 34px -10px rgba(16,38,58,.26); } * { box-sizing: border-box; margin: 0; padding: 0; } /* The sky is painted on , not : with background-attachment:fixed the canvas needs the root box, otherwise it stops at the body's own width. */ html { -webkit-font-smoothing: antialiased; text-size-adjust: 100%; color-scheme: only light; min-height: 100%; background: /* clouds sit BELOW the headline zone — white type needs deep sky behind it.
