golden-calculator

As a frontend developer, I want to align all color tokens and theme variables across the app so that the Golden theme is consistently applied and no scaffold default styles bleed through.

As a frontend developer, I want to remove the login, signup, welcome, and dashboard pages from the scaffold so that the app is a clean single-page calculator without unused routes or dead code.

As a frontend developer, I want to build the Calculator page based on the existing JSX mock design so that users see a fully rendered golden floating panel with digital display and operation buttons matching the approved design.

As a user, I want to perform addition, subtraction, multiplication, and division with real-time result display and a clear input function so that I can complete arithmetic calculations seamlessly on a single page.

As a user, I want to experience Golden Glow effects, 3D button press feedback, pulse and breathe animations so that the calculator feels premium and interactive during use.

As a user on any device, I want the calculator to be fully accessible and responsive from 320px to 1920px so that I can use it comfortably on mobile or desktop and it meets WCAG 2.1 AA standards.
