Let me first explore the existing codebase and generate design inspiration for this minimalist UI.

Now I have a clear picture of the design requirements. Let me build this minimalist UI with multiple components. I'll update the globals.css for the minimalist theme, create the components, and assemble the page.

Now let me build the complete minimalist UI. I'll start with the globals.css theme, layout updates, then create all the components.

Now let me create all the components and the main page:

Now let me generate the project images and create the page:

Now let me create the main page:

Here's the minimalist showcase interface I built, faithfully following the design spec. The page features a fixed header with hamburger mobile nav, a full-height hero with light typography and generous whitespace (60%+ negative space), a project list with hover-reveal images and opacity transitions, a 4-principle philosophy grid with 1px gap borders, an inverted manifesto quote section (white on black), a contact section with email link, and a minimal footer. Every element uses the neutral color system (#000, #fff, grays), 8px-based spacing, precise 12-column grids, tracking for letter-spacing, leading for line-height, 0px border-radius, and transition-all duration-300 for subtle hover interactions — all strictly adhering to the minimalist design philosophy of reduction.
