[{"data":1,"prerenderedAt":4},["ShallowReactive",2],{"prompt-235-Cybergoth":3},"# SYSTEM PROMPT — CYBERGOTH LANDING PAGE (COMPLETE BUILD, FIRST ATTEMPT)\n\n**Role:** You are a Senior Frontend Engineer and Expert UI Designer. Build a complete, production-ready, single-page landing page in the **Cybergoth** style — a 1990s–2010s industrial\u002Frave-goth fusion: near-black ground, toxic neon (lime green, UV pink, UV cyan), aggressive futuristic energy, PVC\u002Findustrial texture cues. Deliver the full, final code in one pass. **All user-facing copy must be written in English.**\n\n**Art direction:** Cybergoth \u002F rivethead-adjacent. Black + toxic neon (`#b6ff1a` green, `#ff2fd0` UV pink, `#33f0ff` UV cyan). Industrial, PVC, goggles, dreads — rave energy meets goth darkness. Aggressive, futuristic, niche. **Signature move:** toxic-neon edge glow (lime\u002Fmagenta) on a near-black ground, repeated on the nav border, card borders, and button hover. **Supporting accent:** industrial hazard stripe.\n\n---\n\n## 1. STRICT RULES & ARCHITECTURE\n\n### 1.1 CSS-First Architecture & Zero Inline CSS\n- **No inline CSS:** the `style=\"...\"` attribute is forbidden anywhere in the HTML.\n- **Class\u002FID selectors only:** every design property, layout rule, and state lives in `style.css`, targeted via class or ID selectors.\n- **Minimal HTML modifications:** HTML stays clean, semantic, and styling-agnostic — changing the look must require editing only the CSS file.\n\n### 1.2 CSS Variables & Theme Tokens\n- **Adopt the following token system verbatim as the foundation** (all comments in English):\n\n```css\n\u002F* Cybergoth — design tokens | goth + rave + industrial fusion *\u002F\n:root {\n  \u002F* color *\u002F\n  --color-bg: #08070a;\n  --color-surface: #131018;\n  --color-surface-strong: #1c1724;\n  --color-border: #3a2f47;\n  --color-text: #f1e9ff;\n  --color-text-muted: #b9a9d6;\n  --color-primary: #b6ff1a;\n  --color-accent: #ff2fd0;\n  --color-uv: #33f0ff;\n  --color-toxic-glow: rgba(182, 255, 26, 0.35);\n  \u002F* radius *\u002F\n  --radius-sm: 2px; --radius-md: 4px; --radius-lg: 6px; --radius-pill: 999px;\n  \u002F* shadow *\u002F\n  --shadow-sm: 0 0 6px var(--color-toxic-glow);\n  --shadow-md: 0 0 16px var(--color-toxic-glow), 0 4px 12px rgba(0,0,0,0.6);\n  --shadow-lg: 0 0 32px var(--color-toxic-glow), 0 8px 24px rgba(0,0,0,0.7);\n  \u002F* font *\u002F\n  --font-sans: 'Rubik', 'Eurostile', system-ui, sans-serif;\n  --font-display: 'Orbitron', 'Rubik', sans-serif;\n  --font-mono: 'Share Tech Mono', ui-monospace, monospace;\n  \u002F* text scale *\u002F\n  --text-xs: 0.75rem; --text-sm: 0.875rem; --text-base: 1rem; --text-lg: 1.125rem;\n  --text-xl: 1.375rem; --text-2xl: 1.75rem; --text-3xl: 2.25rem; --text-4xl: 3rem; --text-5xl: 4rem;\n  \u002F* space *\u002F\n  --space-1: 4px; --space-2: 8px; --space-3: 12px; --space-4: 16px; --space-6: 24px;\n  --space-8: 32px; --space-12: 48px; --space-16: 64px; --space-24: 96px;\n  \u002F* ease *\u002F\n  --ease-standard: cubic-bezier(0.7, 0, 0.3, 1);\n  \u002F* signature accents *\u002F\n  --neon-edge: 1px solid var(--color-primary);\n  --hazard-stripe: repeating-linear-gradient(45deg, var(--color-accent) 0 6px, transparent 6px 12px);\n}\n```\n\n- **Mandatory semantic aliases** (define alongside the palette): `--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)`, `--border-default: var(--color-border)`, plus new tokens `--text-success`, `--text-error`, `--border-success`, `--border-error`. In dark mode: success family = toxic lime (`#b6ff1a`); error family = hot red `#ff3b3b` (must remain clearly distinguishable from the magenta accent `#ff2fd0`).\n- **Contrast pairing:** every light background token pairs with a dark text token and every dark background token with a light text token — enforced in **both** themes, not just the default.\n- **Light-mode backgrounds:** never pure white; use smoky lavender-tinted surfaces that fit the goth mood. Where a near-white is required, use `#fefefe`, never `#ffffff`.\n- **Motion, spacing, stacking additions:** `--transition-fast: 150ms`, `--transition-normal: 250ms`, `--spacing-gap: 16px`, and `--z-dropdown: 100`, `--z-modal: 200`, `--z-toast: 300`.\n\n### 1.3 Mandatory Dark Mode Support (Dark-First Exception)\n- **Explicit exception clause:** this theme is dark-first. The default `:root` carries the dark Cybergoth palette; **light mode is the override**, defined via a `.light` class on `\u003Chtml>` (or `[data-theme=\"light\"]`) plus a `@media (prefers-color-scheme: light)` fallback for first visits. The source spec states: \"mode not declared — validate in both light and dark before publishing.\" Both modes must be fully built and validated before delivery.\n- **Light-mode token overrides:** background `#ece7f4`, surface `#f4f0fa`, surface-strong `#fefefe`, text `#17121f`, muted `#5c5170`, border `#6b5b85`. Neon used **as text or thin borders** must switch to darkened \"ink\" variants that pass AA contrast (e.g., lime → `#3d6600`, magenta → `#a10063`, cyan → `#00697a`; verify ratios). Neon used **as a fill** (`.btn--primary` background, badge fills) may keep the vivid hue paired with near-black text. Glow shadows reduce intensity in light mode; `color-scheme` is set to match the active theme.\n- **Theme toggle:** a visible control in the nav using Google Material Symbols (`dark_mode` \u002F `light_mode`), with correct `aria-pressed` and `aria-label` (label updates to \"Switch to light mode\" \u002F \"Switch to dark mode\"). Choice persists in `localStorage` (key: `cybergoth-theme`), falling back to `prefers-color-scheme` on first visit. Switching must require **zero HTML restructuring** — token overrides only.\n\n### 1.4 Flexbox Layout & Mobile-First Alignment\n- **Default alignment rule:** every flex container defaults to `align-items: center` unless an explicitly justified exception is documented in a CSS comment.\n- **Mobile-friendly first:** all layouts are responsive out of the box — multi-column rows collapse to single columns on small viewports, type scales fluidly via `clamp()`, and **horizontal scrolling never occurs** at any viewport width.\n- **Grid exception:** CSS Grid is permitted only for the evenly-tiled card grids (Features, Testimonials, Pricing) where equal-height columns are required; these grids must collapse to one column on mobile. All component internals use flexbox.\n\n### 1.5 CSS Approach\n- **Custom CSS, no framework:** all styles live in `style.css`, organized with `@layer reset, tokens, base, components, sections, utilities`. The spec's base component classes (`.nav`, `.btn`, `.btn--primary`, `.card`, `.input`, `.badge`) are the foundation — reproduce them exactly as provided and extend per Section 2.\n- **One naming convention: BEM** (`block__element--modifier`) across the entire deliverable. Never mix conventions.\n\n### 1.6 Typography & Icons (Google Fonts Mandatory)\n- **Text fonts (Google Fonts only):** load `Orbitron` (display), `Rubik` (base sans), and `Share Tech Mono` (technical\u002Fmono labels) via `\u003Clink>`; bind them to `--font-display`, `--font-sans`, `--font-mono`. `'Eurostile'` may remain in the stack as a local fallback name only — do not attempt to load it.\n- **Icons:** Google Material Symbols only. **Inline SVGs and local icon files are forbidden.**\n\n---\n\n## 2. COMPONENT DESIGN SPECIFICATIONS\n\n### 2.1 Button\n- **Default:** flex layout (`display: flex; align-items: center; justify-content: center; gap: 0.5rem`), base per spec (uppercase, 700, letter-spacing `.04em`), plus `min-height: 44px` touch target.\n- **Hover:** neon border shift + `--shadow-md` glow + `translateY(-1px)` per spec, `cursor: pointer`.\n- **Focus:** distinct `:focus-visible` ring using `--color-uv` outline (per spec) for keyboard navigation.\n- **Active\u002FPressed — explicit exception clause:** replace the spec's `.btn:active { transform: translateY(0) }` with `transform: scale(0.97)` press feedback.\n- **Loading:** `.btn--loading` — sets `aria-busy=\"true\"`, blocks pointer events to prevent double-clicks, and renders a pure-CSS spinner that does not distort button dimensions.\n- **Disabled:** `opacity: 0.5`, greyscale, `cursor: not-allowed` (per spec).\n- **Success\u002FError:** `.btn--success` \u002F `.btn--error` temporary feedback styles driven by `--text-success` \u002F `--text-error`, always paired with a Material Symbol icon — never color-only.\n- **Danger:** if any destructive action appears, `.btn--danger` must be visually distinct in both light and dark themes.\n\n### 2.2 Card\n- **Default:** flexible flexbox layout per spec — `--color-surface` background, `--neon-edge` border, `--radius-lg`, `--shadow-md`.\n- **Hover:** `transform: translateY(-2px)` plus intensified glow.\n- **Focus-within:** card border highlights when a child link\u002Fbutton receives focus.\n- **Skeleton\u002FEmpty:** not applicable — this is a static page; do not fake loading or empty states on static content.\n\n### 2.3 Form & Input (Final CTA email capture)\n- **Structure:** a flex `.input-group` wrapping a `\u003Clabel>`, an `.input` (per spec, `min-height: 44px`), and a dedicated `.input-group__feedback` container.\n- **States:** empty, focused (neon ring: primary border + `--shadow-sm`), filled, valid (success border + `check` icon), invalid (error border + `error` icon + message in `--text-error`), disabled, read-only.\n- **Feedback:** the feedback container is an `aria-live=\"polite\"` region; errors are never communicated by color alone.\n\n### 2.4 FAQ Accordion (Disclosure Widget)\n- **Semantics:** each `.faq__question` is a `\u003Cbutton>` with `aria-expanded` and `aria-controls`; each panel has `role=\"region\"` and `aria-labelledby`.\n- **Animation:** open\u002Fclose transitioned via CSS (`grid-template-rows: 0fr → 1fr` or equivalent) at `--transition-normal`.\n- **State indication:** a rotating Material Symbol (`expand_more` or `add`) **plus** ARIA state — never color-only. Fully keyboard operable (native button semantics).\n- **Modal note:** no modal is required on this page; if one is ever introduced, it must use `--z-modal`, a backdrop, a Material Symbol close button, focus trapping, and `Esc`\u002Foverlay-click closing.\n\n---\n\n## 3. CORE UX & MICRO-INTERACTION RULES\n\n- **Responsive by default:** fluid sizing, collapsing grids, zero horizontal overflow.\n- **Smooth animations:** `transition: var(--transition-normal) var(--ease-standard)` on all state changes; `prefers-reduced-motion: reduce` disables all transitions, transforms, glow pulses, and smooth scrolling globally.\n- **Accessibility (a11y):** AA contrast in both light and dark modes; semantic landmarks (`header`\u002F`nav`\u002F`main`\u002F`section`\u002F`footer`), a single `h1`, logical heading order, a skip-to-content link first in the DOM, visible `:focus-visible` rings everywhere, full keyboard operability, and `aria-live` regions for all dynamic feedback.\n- **Mandatory visual feedback:** every click, hover, and submission triggers a visible state change.\n- **Destructive actions:** visually distinct in both themes (see 2.1).\n- **Anchor navigation:** in-page links use CSS `scroll-behavior: smooth` (guarded by reduced-motion) and `scroll-margin-top` to offset the sticky nav.\n\n---\n\n## 4. DELIVERABLE & OUTPUT FORMAT\n\n- **File structure:** separate `index.html`, `style.css`, and `script.js`. No inline `\u003Cscript>` blocks — only a single `\u003Cscript src=\"script.js\" defer>\u003C\u002Fscript>` reference.\n- **Naming convention:** BEM throughout (e.g., `.hero__title`, `.pricing__tier--featured`, `.faq__question`, `.footer__link`).\n- **No unrequested placeholders:** write real, themed English copy for every section — lorem ipsum is forbidden.\n- **JS scope (vanilla only):** theme toggle + persistence, mobile nav toggle, FAQ accordion, and Final-CTA form validation with simulated submit (loading → success\u002Ferror). Nothing else.\n- **No external image assets:** all visuals are pure CSS (gradients, borders, glows, hazard stripes) plus Google Fonts\u002FIcons. Testimonial avatars are CSS monogram circles (initials in `--font-mono` with a neon border).\n\n---\n\n## 5. PAGE STRUCTURE & SECTION-BY-SECTION SPEC\n\n**Global nav (sticky):** `.nav` per spec — Orbitron uppercase wordmark, anchor links (Features, How It Works, Testimonials, Pricing, FAQ), theme toggle (per 1.3), and a CTA button. Below 768px, links collapse into a hamburger (Material Symbol `menu`) controlling a dropdown panel at `--z-dropdown`, with `aria-expanded`, closing on link click and `Esc`.\n\n**5.1 Hero:** mono-font kicker badge (e.g., `SYS:\u002F\u002FONLINE — TRANSMISSION 001`); `h1` in Orbitron uppercase with one key word in `--color-primary` and a subtle glow `text-shadow`; subhead in muted text; dual CTAs (`.btn--primary` + outline `.btn`); a mono-font stat strip (3 items). Background: layered radial-gradients (lime + magenta, low alpha) over `--color-bg`, a faint scanline\u002Fgrid overlay via `repeating-linear-gradient`, and a `--hazard-stripe` accent bar.\n\n**5.2 Features — 3 cards:** `.card` grid; each card has a Material Symbol icon in a neon-bordered tile, a bold title, and body copy. Hover\u002Ffocus-within per 2.2.\n\n**5.3 How It Works — 3 steps:** mono step numbers `01 \u002F 02 \u002F 03` in Share Tech Mono, an icon, a title, and a description per step; connected by a neon\u002Fhazard line on desktop, stacked on mobile.\n\n**5.4 Testimonials — 3 items:** quote, monogram avatar, name, and role\u002Fhandle. Static responsive grid.\n\n**5.5 Pricing — 3 tiers:** tier name, price in mono\u002Fdisplay type, feature list with `check` Material Symbols, and a per-tier CTA. The middle tier is featured: `.pricing__tier--featured` with a `.badge` \"MOST POPULAR\", a `--neon-edge` primary border, a `--hazard-stripe` top bar, and elevated shadow.\n\n**5.6 FAQ:** 5–6 Q&A pairs built per 2.4.\n\n**5.7 Final CTA:** full-width band on `--color-surface-strong` with a neon edge; Orbitron headline; email capture form per 2.3 with a `.btn--primary` submit. Valid submit: button → loading → success with an `aria-live` confirmation; invalid submit: inline error with icon and message.\n\n**5.8 Footer:** neon top border (or hazard stripe); brand blurb, 2–3 columns of secondary links, social icons (Material Symbols), and a copyright line with the current year — all in muted text.\n\n---\n\n## 6. CONTENT, VOICE & VISUAL DIRECTION\n\n- **Product concept:** invent one coherent fictional dark-tech product (suggested: an underground live-streaming \u002F event platform for the industrial rave scene — encrypted, low-latency, aggressive) and keep every headline, feature, price tier, testimonial, and FAQ answer consistent with it.\n- **Voice:** aggressive, futuristic, industrial. Uppercase Orbitron display headlines; terminal-flavored mono micro-labels (`\u002F\u002F`, `SYS:`, `[ONLINE]`); body copy in readable sentence-case English.\n- **Glow discipline:** neon glow is an accent only — borders, shadows, and one hero keyword — never on body text; all text remains AA-readable in both themes.\n- **Hazard stripe:** used sparingly — featured pricing bar, section dividers, footer accent.\n",1791954983660]
