   service.css — shared stylesheet for the Crewsive service pages
   (ai-automation, custom-software, web-design, seo-services,
   paid-advertising, marketing-funnels).

   Self-contained + light by design. These are SEO/AEO landing
   pages: the content lives in static HTML, so crawlers (Google,
   GPTBot, PerplexityBot, ClaudeBot) read it with zero JS. The
   visual system mirrors the live React site — same OKLCH ink-blue
   palette, Instrument Serif / Inter Tight pairing, engineering-
   paper dot grid, atmosphere light-pool + grain — but none of the
   heavy canvas/shader/scrolljack machinery, to keep Core Web
   Vitals fast (a ranking input).
