On top of AuthFormBackground.module.scss, I had to make some changes to other files.

app/(pages)/_components/AuthForm/AuthForm.tsx

• Removed judge-only froggy/drumstick decorative markup (design no longer uses it).
• Added real arrow icon (arrow-right.svg) inside the judge submit button content so icon/color can be styled correctly (instead of relying on text arrow).
• Added hasTypedInput logic to apply an inverted button style as soon as users type in inputs (requested behavior; not possible with CSS-only due to React state ownership).

app/(pages)/judges/_components/AuthFormBackground/AuthFormBackground.tsx

• Added structural wrappers/classes (logo_container, section class combinations) to support rotating cloud behind logo and - layout control for vertical centering/bottom anchoring.

app/(pages)/judges/_components/AuthForms/LoginForm.tsx

• Updated label text from “Email” to “Username” per design/content request.
• Removed hardcoded text arrow from buttonText because arrow is now rendered as an icon in AuthForm.tsx.

app/(pages)/judges/_components/AuthForms/ForgotPasswordForm.tsx

• Removed hardcoded text arrow from buttonText for consistency with icon-based button rendering.
