Redesigned sign-in and sign-up with split-screen layout and AuthPageNav

Split-screen auth pages with a benefits panel — Sign-in and sign-up pages were redesigned to a split-screen layout: the authentication form sits on one side and a short, actionable benefits panel sits on the other. The benefits panel highlights key product value (examples below) so new and returning users understand what they get before signing in. - Connect any GitHub repository - Instant changelog generation from commits - Draft → approve → publish workflow - Hosted, shareable changelog at your-project.suprlogs.app

Added a split-screen sign-in and sign-up layout that shows the auth form alongside a short benefits panel to explain value and next steps.frontend
Added a reusable AuthPageNav at the top of auth pages with the brand logo, theme toggle, and a clear link to the opposite action (Sign in / Sign up).auth

Updated the look and feel of the Clerk sign-in/sign-up forms (buttons, labels, and colors) for clearer calls to action and a more consistent visual style.frontend
Updated on-page copy to make it easier to understand next steps (connect a repo, generate changelogs, publish) and to surface the "Sign up free" / "Sign in" links more prominently.frontend
