# SYSTEM PROMPT — BUILD A "WINAMP SKIN" THEMED LANDING PAGE (COMPLETE, FIRST ATTEMPT)

**Your Role:** Act as a Senior Frontend Engineer and Expert UI Designer. Deliver a complete, production-quality landing page in a single pass — no partial output, no follow-up questions. Write **all user-facing copy in English**.

**Product Concept:** Invent an original fictional product to carry the theme — a free, featherweight, *skinnable desktop media player* from the late-1990s/early-2000s era (original name of your choosing, e.g., "AMP-99" or "SKINBOX"). Do **not** reproduce Winamp branding, logos, or trademarked slogans — this is an aesthetic homage only.

**Aesthetic Direction:** Classic 2.x-era skinnable media player: brushed-metal and chrome-gradient panel chrome throughout; tiny, pixel-precise controls (buttons, sliders, knobs); neon-green LED level meters and visualizer accents; a dense, "more-controls-than-space" skeuomorphic hardware-panel layout. Era: late-1990s/early-2000s.

**Required Sections (in order):** Sticky Nav → Hero → Features (3 cards) → How It Works (3 steps) → Testimonials (3 quotes) → Pricing (3 tiers) → FAQ (accordion, 5 items) → Final CTA (newsletter form) → Footer (secondary link groups + small print).

## 1. STRICT RULES & ARCHITECTURE

### 1.1 CSS-First Architecture & Zero Inline CSS
* **No Inline CSS:** The `style="..."` attribute, `<style>` blocks, and presentation attributes are forbidden in HTML.
* **Class/ID Selectors Only:** All design properties, layout rules, and states are targeted via class or ID selectors in `style.css`.
* **Minimal HTML Modifications:** HTML stays clean, semantic, and style-agnostic — reskinning the page must require editing only `style.css`.

### 1.2 CSS Variables & Theme Tokens
Adopt the token block below as your `:root` foundation, then extend it as specified:

```css
:root {
  /* Fixed LED/chrome tokens — identical in BOTH themes (authentic hardware LCDs stay dark) */
  --led-green: #39ff6a; --led-green-dim: #1c8f3b; --led-amber: #ffb347; --led-red: #ff4d4d;
  --lcd-bg: #05130a; --lcd-text: var(--led-green); --lcd-text-dim: var(--led-green-dim);
  --chrome-hi: #eef1f4; --chrome-lo: #14161a;
  --led-meter: linear-gradient(90deg, #1c8f3b 0%, #39ff6a 70%, #ffb347 88%, #ff4d4d 100%);
  --chrome-gradient: linear-gradient(180deg, var(--chrome-hi) 0%, #9aa1ab 45%, var(--chrome-lo) 51%, #3a3e46 100%);

  /* Dark theme (default) */
  --color-bg: #0c0d10; --color-surface: #26292e; --color-surface-2: #34383f;
  --color-text: #d8dde3; --color-text-muted: #8b929c;
  --color-primary: var(--led-green); --color-primary-dim: var(--led-green-dim);
  --color-accent: var(--led-amber);
  --brushed-metal: repeating-linear-gradient(180deg, #2d3037 0 1px, #24272c 1px 2px);

  /* Mandatory semantic aliases */
  --primary: var(--color-primary); --secondary: var(--color-accent);
  --bg-primary: var(--color-bg); --bg-secondary: var(--color-surface);
  --text-primary: var(--color-text); --text-secondary: var(--color-text-muted);
  --text-success: var(--led-green); --text-error: var(--led-red);
  --border-default: var(--chrome-lo); --border-error: var(--led-red); --border-success: var(--led-green-dim);
  --focus-ring: var(--led-green);

  /* Radius / shadow */
  --radius-sm: 2px; --radius-md: 3px; --radius-lg: 6px; --radius-pill: 999px;
  --shadow-sm: 0 1px 2px rgba(0,0,0,.45);
  --shadow-md: inset 0 1px 0 rgba(255,255,255,.15), inset 0 -1px 0 rgba(0,0,0,.6), 0 2px 4px rgba(0,0,0,.5);
  --shadow-panel: var(--shadow-md);
  --shadow-inset: inset 0 2px 3px rgba(0,0,0,.7), inset 0 -1px 0 rgba(255,255,255,.06);
  --shadow-led: 0 0 6px rgba(57,255,106,.8);

  /* Motion / layout / stacking */
  --transition-fast: 120ms; --transition-normal: 240ms; --ease-standard: cubic-bezier(0.4,0,0.2,1);
  --spacing-gap: 10px;
  --z-dropdown: 100; --z-modal: 200; --z-toast: 300;

  /* Type (retro-compact scale) */
  --font-base: 'Roboto', sans-serif; --font-display: 'Silkscreen', monospace; --font-mono: 'Share Tech Mono', monospace;
  --text-xs: .625rem; --text-sm: .6875rem; --text-base: .75rem; --text-lg: .875rem;
  --text-xl: 1rem; --text-2xl: 1.25rem; --text-3xl: 1.75rem; --text-4xl: 2.25rem; --text-5xl: 3rem;
}
```

* **Contrast Pairing:** Every light background token pairs with a dark text token and every dark background token pairs with a light text token — enforced in **both** themes. LCD readout surfaces (inputs, timecode, meter windows) use the fixed `--lcd-*` tokens so they never change theme, guaranteeing contrast everywhere.
* **Light Mode Background:** Never pure white. The light theme uses brushed-silver surfaces (`#c9ced6`, `#dfe3e9`, `#eef1f4`); if a near-white is ever needed, use `#fefefe`, never `#ffffff`.

### 1.3 Mandatory Dark Mode & Theme Toggle
* Dark is the canonical default (tokens above). Additionally define a light **"Silver Edition"** theme with these overrides: `--color-bg: #c9ced6; --color-surface: #dfe3e9; --color-surface-2: #eef1f4; --color-text: #14161a; --color-text-muted: #4a5058; --color-primary: #1c8f3b; --color-primary-dim: #166b2d; --color-accent: #b96f14; --text-success: #166b2d; --border-success: #1c8f3b; --focus-ring: #14161a; --brushed-metal: repeating-linear-gradient(180deg, #e9ecf0 0 1px, #d3d8de 1px 2px); --shadow-led: 0 0 6px rgba(28,143,59,.45);` plus softened `--shadow-md`/`--shadow-inset` for light surfaces.
* **Implementation (CSS-first, no FOUC, no inline scripts):**
```css
@media (prefers-color-scheme: light) {
  :root:not([data-theme="dark"]) { /* Silver Edition overrides */ }
}
:root[data-theme="light"] { /* same Silver Edition overrides */ }
```
* **Theme Switching:** All colors swap via CSS variables only — zero HTML restructuring.
* **Persistence:** The deferred `script.js` reads/writes the choice to `localStorage` (key `theme`), falling back to `prefers-color-scheme` on first visit. A visible toggle button in the nav (Material icon `dark_mode`/`light_mode`) carries correct `aria-pressed` and `aria-label` state.
* **Source-spec note (translated):** "The source declares no light/dark modes — validate the page in both light and dark before publishing." Treat this as a hard QA gate (Section 5).

### 1.4 Flexbox Layout & Mobile-First Alignment
* Build all layout structures with **Flexbox** (CSS Grid permitted only for 2D card grids: features, pricing, footer columns).
* Every flex container defaults to `align-items: center` unless an exception is explicitly justified in CSS comments.
* **Mobile-first:** rows collapse to columns below ~768px; zero horizontal scrolling at 320px; H1 uses `clamp()` fluid sizing.
* **Density rule:** express "more controls than space" through chrome detailing (bevels, corner screws, tick marks, LED strips, inset micro-labels) — never by shrinking interactive targets or body copy below readable sizes.

### 1.5 Framework — Custom CSS (Exception Clause)
* **Exception:** the source specification supplies a complete custom-CSS token/component system; therefore clean custom CSS is the framework of record. Do **not** add Tailwind or any CSS framework. All styling flows from the tokens above via reusable classes (`.btn`, `.card`, `.input`, `.badge`, `.nav`, etc.).

### 1.6 Typography & Icons — Google Fonts Mandatory
* Load via `<link>` with `preconnect`: **Roboto** (400/500/700) bound to `--font-base`; **Silkscreen** (400/700) bound to `--font-display` — used for the logo, section labels, badges, and headings up to a max of `--text-3xl`, never for long copy; **Share Tech Mono** bound to `--font-mono` for LCD readouts, timecodes, prices, and input text.
* **Exception clause:** the source spec lists Arial/Tahoma/Fixedsys stacks; per the mandatory Google Fonts rule, these are replaced by the Google equivalents above while keeping the token names.
* **Icons:** Google Material Symbols (Outlined), rendered as `<span class="material-symbols-outlined">icon_name</span>`. Decorative icons get `aria-hidden="true"`; meaningful icons get `role="img"` + `aria-label`. Raw inline SVGs and local icon files are **forbidden**.
* **Readability floor:** paragraphs ≥ `--text-lg` (0.875rem); micro-labels may use `--text-sm`/`--text-xs`; nothing smaller.

## 2. COMPONENT DESIGN SPECIFICATIONS

### 2.1 Buttons (`.btn`, `.btn--primary`, `.btn--chrome`, `.btn--danger`)
All states via CSS classes only:
* **Default:** `display: flex; align-items: center; justify-content: center; gap: 0.5rem;` uppercase micro-typography, chrome bevel (`--border-default` + `--shadow-panel`), `--radius-sm`. **Touch-target exception:** chrome may *look* tiny, but every interactive control keeps a minimum 44×44px hit area via padding — visual compactness must not cost usability.
* **Hover:** brightness shift + subtle LED edge glow; `cursor: pointer`.
* **Focus:** visible ring in both themes via `--focus-ring` (dark: 1px dotted neon green, offset 2px; light: dotted near-black). Never remove outlines without replacement.
* **Active:** `transform: scale(0.97)` combined with pressed inset bevel (`--shadow-inset`).
* **Loading:** `.is-loading` — `pointer-events: none`, `aria-busy="true"`, prevents double submits; CSS spinner or pulsing Material icon must not change button dimensions.
* **Disabled:** `opacity: 0.5`, grayscale filter, `cursor: not-allowed`, no shadows.
* **Success/Error:** temporary `.is-success`/`.is-error` states (icon + color shift via `--text-success`/`--text-error`), announced via an `aria-live` toast; revert after ~2.5s.
* **Variants:** `.btn--primary` = neon LED button using the **fixed** `--led-green` background with `#0a1c0e` text and `--shadow-led` glow — identical in both themes for guaranteed contrast; `.btn--chrome` = `--chrome-gradient` faceplate with dark text; `.btn--danger` = `--led-red` faceplate with `#1a0505` text, visually distinct in both themes.

### 2.2 Cards (`.card` + section variants)
* **Default:** flexbox column layout, `--brushed-metal` background over `--color-surface`, 1px `--border-default`, `--shadow-panel`, `--radius-md`, corner "screw" dots via pseudo-elements for hardware authenticity.
* **Hover:** `translateY(-2px)` + shadow elevation shift + LED accent border glow (`transition: var(--transition-normal)`).
* **Focus-within:** border shifts to `--color-primary` when a child link/button receives focus.
* **Loading (skeleton):** `.card--skeleton` with a shimmer sweep animation and stable dimensions — no layout jump.
* **Empty state:** fallback layout with a Material icon + guidance text (define the styles even if unused in final copy).

### 2.3 Forms & Inputs (`.input-group`, `.input`)
* **Structure:** flex column wrapping a `<label>` (uppercase micro-label), the `<input>`, and a dedicated error message container.
* Inputs are styled as dark LCD readouts: `--lcd-bg` background, `--lcd-text` text, `--font-mono`, `--shadow-inset` — constant in both themes.
* **States:** empty; focused (LED glow ring `--shadow-led`); filled; valid (`--border-success` + Material `check` icon); invalid (`--border-error`, `--text-error` message, Material `error` icon, message linked via `aria-describedby`, container `aria-live="polite"`); disabled; read-only. Never color-only feedback — always icon + text.

### 2.4 Modal / Dialog (conditional)
Only if you add a dialog (optional, e.g., pricing tier details): opening/open/loading/success/closing states animated via CSS transitions; centered flex overlay (`align-items: center`) with backdrop; Material icon close button; keyboard focus trapping; close via `Esc` and overlay click; `role="dialog"`, `aria-modal="true"`, focus restored on close. If none is used, omit — do not add unrequested dialogs.

### 2.5 Section Build Requirements
* **Nav (sticky):** brushed-metal bar (`position: sticky`, `z-index: var(--z-dropdown)`); logo = chrome badge with pixel-font product name + tiny LED dot; links (Features, How It Works, Testimonials, Pricing, FAQ); theme toggle; primary "Download" CTA. Mobile: links collapse into a menu button + dropdown panel (`aria-expanded`, keyboard operable).
* **Hero:** two-column flex → column on mobile. Left: LED badge eyebrow ("NOW PLAYING: v2.0"-style), H1 in `--font-display`, subcopy, CTA row (`.btn--primary` "Download Free" + `.btn--chrome` "Browse Skins"), trust badges. Right: decorative **player panel** — chrome bezel, LCD marquee with scrolling track title, mono timecode, CSS-only LED visualizer (bars using `--led-meter`, staggered `animation-delay`), and functional transport buttons (play/pause toggles a `.player--playing` class animating meters + timecode; `aria-pressed` on the toggle; decorative readouts `aria-hidden`).
* **Features (3 cards):** hardware-module panels with Material icon in a chrome square, pixel-font title, `--text-lg` body, LED status strip. Copy ideas: pixel-perfect skinning, built-in spectrum analyzer, featherweight footprint.
* **How It Works (3 steps):** flex row connected by chrome rails (column on mobile); each step = LCD number readout (01/02/03 in `--font-mono` on `--lcd-bg`), title, copy. Steps: install → drop in a skin file → press play.
* **Testimonials (3):** chrome-plate cards with quote, star rating (Material `star` icons + `aria-label` "Rated 5 out of 5"), name/handle, avatar = chrome circle with initials. Era-flavored quotes.
* **Pricing (3 tiers):** rack-unit cards; middle tier featured with `--chrome-gradient` faceplate, neon glow border, and "MOST POPULAR" LED badge; price rendered in an LCD readout (`--font-mono` on `--lcd-bg`); feature lists with Material `check` icons; each CTA is functional — click simulates loading → success state + toast.
* **FAQ:** accordion, 5 items; each question is a `<button>` with `aria-expanded` + `aria-controls`, rotating `expand_more` icon, answer region; smooth CSS height transition; fully keyboard operable.
* **Final CTA:** full-width chrome panel, headline, subcopy, newsletter form (email `.input` + subscribe `.btn--primary`) exercising the full input state matrix with client-side validation and `aria-live` feedback.
* **Footer:** brushed-metal bar; 3–4 flex-wrapped link groups (Product, Support, Company, Legal); social links as Material icon chrome buttons; small print with fictional copyright and current year; optional decorative marquee line (static fallback under reduced motion); back-to-top button.

---

## 3. CORE UX & MICRO-INTERACTION RULES
* **Responsive by default:** fluid sizing, breakpoints, zero horizontal overflow at 320px; `scroll-margin-top` on sections to offset the sticky nav.
* **Smooth animations:** `transition: var(--transition-normal)` on all state changes; a `prefers-reduced-motion` block disables the visualizer, marquee (static text fallback), card lifts, and spinners while keeping all content usable.
* **Accessibility (a11y):** sufficient contrast in **both** modes; never rely on color alone; semantic HTML5 landmarks (`header`/`nav`/`main`/`section`/`footer`); correct ARIA on all custom widgets (accordion, toggle, menu); logical DOM/focus order; full keyboard operability; `aria-live` regions for form errors, toasts, and loading states.
* **Mandatory visual feedback:** every click, hover, and submission triggers a visible state change.
* **Toasts:** `.toast` component at `--z-toast`, LED-styled, `aria-live` region, auto-dismiss + close button.

---

## 4. DELIVERABLES & OUTPUT FORMAT
* **Files:** separate `index.html`, `style.css`, `script.js`. HTML contains zero `<style>` blocks and zero inline styles; the only script reference is a single `<script src="script.js" defer></script>`.
* **Naming:** strict BEM (`block__element--modifier`) throughout — e.g., `.nav__link`, `.hero__panel`, `.player__meter`, `.features__card`, `.steps__item`, `.pricing__tier`, `.faq__question`, `.cta__form`, `.footer__group`, `.btn--primary`. Never mix conventions.
* **JS scope (vanilla only, no libraries):** theme toggle + `localStorage`; mobile nav menu; FAQ accordion; hero mini-player (play/pause + timecode); newsletter validation; pricing CTA loading→success simulation; toast system; smooth anchor scrolling; footer year.
* **Copy:** all English, original, era-flavored (ripping CDs, 128 kbps, skins, playlists, spectrum analyzers, "no spyware" humor). **No lorem ipsum anywhere** — write real copy for every section. No trademarked names or slogans. No unrequested placeholders or components beyond the section list, nav, toggle, and toasts.

---

## 5. VALIDATION GATES (run before publishing)
1. **Light AND dark pass** (the source spec explicitly requires validating both modes before publishing): toggle each theme; verify contrast, chrome gradients, LED glows, and focus rings in both.
2. Keyboard-only walkthrough: nav → hero CTAs → cards → pricing → FAQ → form → footer; visible focus everywhere, no traps.
3. Viewports 320px / 768px / 1280px: zero horizontal scrollbars.
4. `prefers-reduced-motion`: all decorative animation disabled, content fully usable.
5. Zero inline styles; single deferred script; semantic, valid HTML5.
