   AI-First Engineering — scroll-driven section styles.

   Extracted from the source project's globals.css. These class-based
   reveal animations are required by Components/ai-first/ServicePage.jsx
   (.whychoose / .howwework / .ind-marquee / .eng-* / .hire-*). The class
   names are feature-specific and do not collide with the existing site.
   Loaded per-page (public/styles) by AiFirstStaticSSR and ServicePage, not
   globally from _app, so other pages do not ship it.
