Layer / File(s)	Summary
Layout hooks and component structure src/components/AnalysisBanner.jsx, src/components/RateLimitBanner.jsx, src/components/layout/Footer.jsx, src/pages/HomePage.jsx, src/pages/OverviewPage.jsx	Components add CSS classes for responsive styling. Existing rendering and most behavior remain unchanged.

Responsive content and footer styling src/styles/global.css	Media queries adjust navigation, overview grids, banners, rate-limit content, organization cards, home statistics, and footer layout across viewport widths.
Base style formatting src/styles/global.css	Existing theme properties, element rules, scrollbar rules, and keyframes are reformatted without changing values.

Merge Risk: 🔵 Low · up to cc1b2

Mobile navigation has untranslated headings and can display controls with overly compact styling. These are bounded responsive UI issues that should be addressed before release.

I stack the links and guide each friend
The banners shrink, the footers flow
A menu blooms when links overflow
Responsive hops now neatly land}
