Album App

Build a full-screen music album carousel page. Single-page React + TypeScript + Vite + Tailwind CSS app. Use `lucide-react` for icons only (ChevronLeft, ChevronRight, ArrowLeft). No other dependencies. Import Google Fonts Inter (weights 300, 400, 500, 700). Body uses `font-family: 'Inter', sans-serif` and `overflow: hidden`.

## TEXT COLOR LOGIC

Colors `#940C4F`, `#002AA6`, `#D34607` are dark -- use white text (`text-white`). Colors `#AEDC40` and `#FDC809` are light -- use dark text (`text-gray-900`). All text and UI elements adapt based on the current slide's color. Navigation button backgrounds use `bg-white/10` on dark slides, `bg-black/10` on light slides.

---

## MAIN LAYOUT (Carousel View)

Full viewport (`h-screen w-full overflow-hidden`). Solid background color from the active slide. Content padded `px-6 md:px-16 lg:px-24`, `pt-8 pb-8 md:py-12 md:pt-12`.

**Top section** (flexbox, `md:flex-row`, column on mobile, `mb-auto`):
- Left: Slide title as `<h1>`, `text-4xl md:text-6xl`, `font-light`, `tracking-tight leading-none`, `max-w-xs md:max-w-sm`. Uses Inter font explicitly.
- Right: Slide description in `<p>`, `text-sm md:text-base`, `leading-relaxed opacity-80`, inside a `max-w-md` wrapper.

**Carousel section** (flex-1, centered vertically and horizontally):
- Container: `relative w-full flex items-center justify-center h-[280px] md:h-[480px]`.
- Each slide is `position: absolute` with inline styles for transform, zIndex, opacity.

---

## CAROUSEL CARDS (IMPORTANT: No shadow, no background, no border)

Each card is a single div wrapping an img. The div has ONLY these classes: `w-[240px] h-[240px] md:w-[480px] md:h-[480px] rounded-2xl overflow-hidden`. The img has ONLY: `w-full h-full object-cover`.

**DO NOT add any of the following to carousel cards:** `shadow`, `shadow-lg`, `shadow-2xl`, `bg-*`, `border`, `ring`, or any elevation/card styling. The images float directly on the colored background with no visible frame. The ONLY visual boundary is the `rounded-2xl` clip from `overflow-hidden`. No wrapper div with background or shadow should exist around the cards.

The outer positioning wrapper (the absolutely-positioned div that handles transforms) also has ZERO visual styling -- only `position: absolute`, a cursor style on the active card, and the inline style object.

---

## CAROUSEL TRANSFORMS

Calculate offset from center using modulo wrapping (infinite loop both directions):
- **Center card (offset 0):** `scale(1.1)`, `rotate(0deg)`, `translateX(0)`, `zIndex: 10`, `opacity: 1`.
- **Adjacent cards (offset +/-1):** `scale(0.85)`, `rotate(+/-14deg)`, `translateX(+/-260px)` mobile / `translateX(+/-480px)` desktop, `zIndex: 4`, `opacity: 1`.
- **Cards beyond 1 position away:** `opacity: 0` (hidden).
- All transitions: `all 0.7s cubic-bezier(0.4, 0, 0.2, 1)`.

---

## NAVIGATION BUTTONS

Two circular buttons below the carousel, `flex items-center gap-4`, centered. Each button: `w-10 h-10 rounded-full flex items-center justify-center backdrop-blur-sm`. Background: `bg-white/10` on dark, `bg-black/10` on light. Hover: `scale-110`. Icons: ChevronLeft and ChevronRight from lucide-react, `w-5 h-5`, same text color class as other text.

On mobile only, show the current slide title (`text-lg font-light tracking-widest`) above the nav buttons.

---

## BACKGROUND TRANSITION (Circle Reveal)

When navigating to a new slide, trigger a circle-expand animation:
- Render a div with the NEW slide's color. Position it absolutely at `top: 50%; left: 50%` with `width: 250vmax; height: 250vmax; border-radius: 50%; margin-top: -125vmax; margin-left: -125vmax`. This centers a massive circle that will cover the entire screen when fully scaled.
- Apply CSS animation: `transform: scale(0)` to `scale(1)` over `2400ms` with timing function `cubic-bezier(0.05, 0.7, 0.1, 1)`, `animation-fill-mode: forwards`.
- The div sits at `z-index: 1` (above the base background, below the content at z-index 2). Pointer-events none.
- After 2400ms (via setTimeout), update the base background color to the new color and remove/unmount the circle div.
- Use a `key` prop (incrementing counter) to force React to remount a fresh circle div on each navigation.

---

## DETAIL VIEW (Click center card to open)

Clicking the center carousel image opens an album detail overlay.

**Opening sequence:**
1. Set `detailAnimating = true`, then after 50ms set `detailView = true` (to trigger CSS transitions).
2. The carousel wrapper transitions to `opacity-0 scale-95` with `duration-700 ease-out` and `pointer-events-none`.
3. The detail overlay (absolute, inset-0, z-index 3) becomes visible.

**Desktop layout (hidden on mobile, `md:flex`):**

Left half (50% width, `relative h-full flex items-center`):

- **Vinyl disc (background element):** A `480x480` div with `rounded-full overflow-hidden` containing the slide's carousel `image` as an `<img>` with `w-full h-full object-cover rounded-full`. NO shadow. This is positioned `absolute`, `top-1/2 -translate-y-1/2`. It animates:
  - `left` from `calc(50% - 240px)` to `calc(25% - 290px)` 
  - `transform rotate` from `0deg` to `90deg`
  - Duration: `2000ms`, timing: `cubic-bezier(0.4, 0, 0.1, 1)`

- **Album cover (foreground, z-10):** A rectangular div, `w-[340px] h-[440px] lg:w-[420px] lg:h-[540px]`, with `overflow-hidden shadow-2xl` and `margin-left: -40px`. NO border-radius (sharp rectangle). Contains the slide's `albumCover` image with `object-cover object-right`. Slides in from `-translate-x-full` to `translate-x-0` over `900ms ease-out`. The `shadow-2xl` belongs ONLY to this rectangle.

Right half (`flex-1`, padded `pr-8 md:pr-16 lg:pr-24 pl-8 lg:pl-12`):
- Title: `text-4xl md:text-5xl lg:text-6xl font-light tracking-tight leading-none mb-2`
- Year: `text-lg md:text-xl opacity-60 mb-8`
- Description: `text-sm md:text-base leading-relaxed opacity-70 mb-10 max-w-md`
- "Buy Now" button (see styling below)
- Entire right column fades in with `translate-x-12` to `translate-x-0`, `duration-700 ease-out`, `transition-delay: 300ms`.

**Mobile layout (md:hidden, stacked, scrollable with `overflow-y-auto`, `pt-20 px-6 pb-8`):**
- Album cover: `w-[280px] h-[360px] rounded-lg shadow-2xl mb-8`. Fades up from `translate-y-8`.
- Text block (center-aligned): title `text-3xl`, year `text-lg opacity-60 mb-6`, description `text-sm max-w-sm mx-auto mb-8`, then Buy Now button. Fades up with 200ms delay.

**Close button:** ArrowLeft icon, positioned `absolute top-6 right-6 md:top-8 md:right-16`, z-10. Same circular style as nav buttons (`w-10 h-10 rounded-full backdrop-blur-sm`). Fades in from `-translate-y-4` to `translate-y-0` with 400ms delay.

**Closing:** Set `detailView = false` (elements animate out via their transition classes returning to initial state). After 800ms timeout, set `detailAnimating = false` to unmount the overlay and restore the carousel.

---

## BUY NOW BUTTON

`px-12 py-3 border rounded-sm text-sm tracking-widest uppercase`. On dark backgrounds: `border-white/40 text-white hover:bg-white/10`. On light: `border-gray-900/40 text-gray-900 hover:bg-gray-900/10`. Hover: `scale-105`. Transition: `duration-300`.

## CSS (index.css)

```css
@import url('https://fonts.googleapis.com/css2?family=Inter:wght@300;400;500;700&display=swap');

@tailwind base;
@tailwind components;
@tailwind utilities;

* { margin: 0; padding: 0; box-sizing: border-box; }

  to { transform: scale(1); }
}
.circle-reveal {
  animation: circleExpand 2400ms cubic-bezier(0.05, 0.7, 0.1, 1) forwards;
}

@keyframes vinylSpin {
  from { transform: rotate(0deg); }
  to { transform: rotate(360deg); }
}
.vinyl-spin { animation: vinylSpin 4s linear infinite; }

@keyframes trackFadeIn {

  to { opacity: 1; transform: translateX(0); }
}
.detail-track-in { animation: trackFadeIn 500ms cubic-bezier(0.2, 0.8, 0.2, 1) forwards; }

.cubic-bezier-smooth { transition-timing-function: cubic-bezier(0.4, 0, 0.1, 1); }
```

---

## STATE MANAGEMENT

Single component, no routing. React state:
- `currentIndex` (number) -- active slide
- `bgColor` (string) -- current solid background
- `nextBgColor` (string | null) -- color for circle reveal, null when not transitioning
- `transitionKey` (number) -- incrementing key to remount circle div
- `detailView` (boolean) -- controls CSS transition classes on detail elements
- `detailAnimating` (boolean) -- controls mount/unmount of detail overlay

Carousel wraps infinitely using modulo arithmetic in both directions.

---

## RESPONSIVE BREAKPOINTS

- Mobile (<768px): Cards 240x240, translateX offset 260px. Detail stacks vertically. Mobile-only title below carousel. Padding px-6, pt-8 pb-8.
- Desktop (>=768px): Cards 480x480, translateX offset 480px. Detail is side-by-side. Padding px-16, py-12.
