- runtimes: bordered "supported runtimes" strip, text-based for consistency
(Reicon brand coverage is partial); all eight runtimes preserved
- how-it-works: centered heading + clean numbered stepper for the seven-step
first-run flow; drop the framer-motion terminal demo
- faq: adaline accordion (grid-rows expand, Reicon plus icon); all answers
preserved, including the platform-support-derived ones
- move all three into components/sections and remove the old flat components
