zyan.ai: New Header, Real Product Media, Calmer Status

zyan.ai gets a floating header that docks solid on scroll, product pages built from real captures of the app with step-by-step sections, a rebuilt Growth page, and a status page with a Report an issue form. The Features page is retired.

• How it works step cards and feature grids on the product pages
• Status page: report an issue from a form, thinner uptime bars, no pulsing dots
• A wider changelog, so every entry takes fewer lines
