Your task is to code a complete, production-quality Landing Page **on the first attempt**. Deliver a finished, runnable website — no scaffolds, no TODOs, no lorem-ipsum-only content.\n\n**Project Definition**\n\n- **Theme:** HUD \u002F Sci-Fi FUI — Sci-Fi, Technical, Dark, Interface-Driven (2010s Sci-Fi era)\n- **Style keywords:** futuristic, technical, wireframe, neon, data, transparency, iron man, sci-fi, interface\n- **Mode support:** Full dark mode (canonical default) + a low-light \"Daylight Ops\" light mode\n- **Palette:** Neon Cyan `#00FFFF`, Holographic Blue `#0080FF`, Alert Red `#FF0000`, Transparent Black, Grid Lines `#333333`\n- **Signature effects (all mandatory):** glow effects, scanning animations, ticker text, blinking markers, fine 1px line drawing\n- **Sections (in this exact order):** Hero → Features (3 cards) → How It Works (3 steps) → Testimonials → Pricing (3 tiers) → FAQ → Final CTA → Footer with secondary links\n\n---\n\n## 1. STRICT RULES & ARCHITECTURE\n\n**1.1 CSS-First Architecture & Zero Inline CSS**\n- All styling lives in `style.css`. The `style=\"...\"` attribute is **forbidden** anywhere in `index.html`.\n- Target every element via class or ID selectors only.\n- Keep HTML semantic and style-agnostic: reskinning the page must require editing CSS only, never markup.\n- Build all decorative HUD elements (corner brackets, crosshairs, scanlines, ticks, connector lines, data bars) with CSS borders, pseudo-elements, and gradients — no raster images, no icon glyphs as decoration. Every purely decorative node carries `aria-hidden=\"true\"`.\n\n**1.2 CSS Variables & Theme Tokens**\nDefine all tokens in `:root` (dark = canonical) and override in `[data-theme=\"light\"]`:\n\n- **Dark (default):** `--primary: #00FFFF; --secondary: #0080FF; --alert: #FF0000; --bg-primary: #030608; --bg-secondary: #0A1118; --panel-bg: rgba(0,0,0,0.8); --text-primary: #DFF7FF; --text-secondary: #8FB8C6; --text-success: #00FF9C; --text-error: #FF5C5C; --border-default: rgba(0,255,255,0.5); --border-subtle: rgba(0,255,255,0.25); --border-error: rgba(255,0,0,0.7); --border-success: rgba(0,255,156,0.6); --grid-line: #333333; --glow-cyan: 0 0 5px rgba(0,255,255,0.8); --glow-blue: 0 0 8px rgba(0,128,255,0.6); --radius-sm: 2px; --radius-md: 2px; --radius-lg: 4px; --shadow-sm: 0 0 8px rgba(0,255,255,0.15); --shadow-md: 0 0 20px rgba(0,255,255,0.3); --spacing-gap: 1.5rem; --transition-fast: 120ms; --transition-normal: 250ms; --ease-standard: cubic-bezier(0.2,0.8,0.2,1); --z-header: 900; --z-dropdown: 1000; --z-modal: 2000; --z-toast: 3000; --font-display: 'Orbitron', 'Share Tech Mono', monospace; --font-base: 'Share Tech Mono', 'Courier New', monospace;`\n- **Light (\"Daylight Ops\") overrides:** `--primary: #0066CC; --secondary: #004C99; --bg-primary: #EEF3F6` (cool near-white — never `#ffffff`; use `#fefefe` only if a white surface is truly unavoidable); `--bg-secondary: #E3EBF0; --text-primary: #0A141B; --text-secondary: #3E5A68; --text-error: #C40000; --border-default: rgba(0,102,204,0.45); --grid-line: #C9D4DA; --glow-cyan: none; --glow-blue: none; --shadow-sm\u002F--shadow-md: soft neutral shadows rgba(10,30,50,0.15)`.\n- **Contrast pairing is mandatory per theme:** dark backgrounds pair with light\u002Fcyan text; light backgrounds pair with dark text. Every foreground\u002Fbackground pair must pass WCAG AA (≥4.5:1 body text, ≥3:1 large text and UI borders). `#FF0000` is reserved for decorative borders, glows, and markers; readable error text uses `--text-error`.\n- All borders are 1px (\"fine line drawing\"). Corner chamfers via `clip-path` are allowed; radii come only from the radius tokens. Glows are decorative: apply `--glow-cyan` to headings, labels, and UI accents only — never body paragraphs.\n\n**1.3 Mandatory Dark Mode Support**\n- Dark is this theme's canonical mode; tune every effect for dark first.\n- Implement switching via a `[data-theme]` attribute on `\u003Chtml>` (serving the role of a `.dark` class): default\u002F`:root` = dark tokens; `[data-theme=\"light\"]` applies the light overrides. Add a `@media (prefers-color-scheme: light)` block that activates light tokens only when no explicit `data-theme` is set (no-JS fallback).\n- `script.js` (the single deferred entry point) must apply the persisted theme in its **first synchronous statements**. Persistence via `localStorage` key `\"hud-theme\"`; first visit falls back to `prefers-color-scheme`.\n- Visible toggle control in the header: Material Symbols `dark_mode`\u002F`light_mode` icon with correct `aria-pressed` and a dynamically updated `aria-label` (\"Switch to light mode\" \u002F \"Switch to dark mode\").\n- Set `color-scheme: dark` \u002F `light` alongside each theme so native controls and scrollbars match.\n- Light mode must degrade effects gracefully: glows off, grid lines lightened, scanlines subtle — never leave dark-tuned glows on a light background.\n\n**1.4 Flexbox Layout & Mobile-First Alignment**\n- Build all structural layout with Flexbox: header, section interiors, card rows (flex-wrap), steps, footer columns, button internals.\n- **Every flex container defaults to `align-items: center`.** Any deviation must be an explicitly justified exception marked with a CSS comment (`\u002F* exception: … *\u002F`). Sanctioned exceptions: `.input-group` (column, `align-items: stretch`), long-form text blocks inside panels (`flex-start` for reading alignment), accordion answer text.\n- Use `var(--spacing-gap)` as the standard flex gap. Mobile-first: single column at base; wrap into rows at ≥768px; refine at ≥1024px\u002F≥1280px. **No horizontal scrolling at any width down to 320px** — audit fixed decorations, tickers, and glows for overflow; clip or hide the viewport frame below 480px.\n\n**1.5 Styling Stack**\n- Use **clean, hand-written custom CSS driven by Tailwind-style cascade layering**: organize `style.css` as `@layer tokens, base, components, sections, utilities`. No external CSS framework, no build tools — the page must run by opening `index.html`.\n- All component classes map exclusively to the tokens: `.btn` (+ `.btn--primary\u002F--ghost\u002F--danger`), `.hud-panel` (+ `.hud-panel--featured`), `.input-group`, `.nav`, `.ticker`, `.faq-item`, etc.\n\n**1.6 Typography & Icons (Google Fonts Mandatory)**\n- Load via `\u003Clink>` with `preconnect`: **Orbitron** (500, 700) for display headings, numerals, and prices; **Share Tech Mono** (400) as the base body\u002FUI face. Bind them to `--font-display` \u002F `--font-base`.\n- **Exception clause (theme spec requests `font-family: monospace`):** satisfy it through the mandatory Google Fonts — `Share Tech Mono` with `monospace` generic fallbacks. Never rely on system monospace alone.\n- Icons: **Google Material Symbols (Outlined)** via `\u003Clink>` for all icons — theme toggle, menu, feature icons, pricing check\u002Fclose, FAQ chevrons, form valid\u002Ferror, social links, close buttons.\n- **Forbidden:** inline SVGs, local icon files, emoji-as-icons, any other icon font.\n- Decorative glyphs (brackets, `+` crosshairs, corner ticks) are CSS-generated, never icons.\n\n---\n\n## 2. COMPONENT DESIGN SPECIFICATIONS\n\n**2.1 Button Component (`.btn`)**\n- **Default:** `display: flex; align-items: center; justify-content: center; gap: 0.5rem;` minimum touch target 44×44px; 1px `var(--border-default)`; transparent background (`.btn--ghost`) or `var(--primary)` fill paired with `--bg-primary` text (`.btn--primary`); `.btn--danger` uses the alert-red family and must be visually distinct in **both** themes.\n- **Hover:** brightness\u002Fglow shift plus a subtle one-shot scan sweep across the button; `cursor: pointer`.\n- **Focus:** distinct `:focus-visible` ring via `outline: 2px solid var(--primary); outline-offset: 2px` plus glow — clearly visible in dark and light.\n- **Active:** `transform: scale(0.97)`.\n- **Loading (`.is-loading` + `aria-busy=\"true\"`):** blocks interaction and double-clicks; renders a CSS spinner (conic-gradient ring) or rotating Material Symbol `progress`; button dimensions must not change.\n- **Disabled (`[disabled]`):** `opacity: 0.5`, grayscale, `cursor: not-allowed`, removed from pointer and keyboard activation.\n- **Success\u002FError (`.is-success` \u002F `.is-error`):** temporary feedback — border, label, and icon switch to `--text-success` \u002F `--text-error` with paired Material icons; never communicate via color alone.\n\n**2.2 Card Component (`.hud-panel`)** — used by Features, Testimonials, Pricing\n- **Default:** flex column; `background: var(--panel-bg)` (dark) \u002F `var(--bg-secondary)` (light); 1px `var(--border-subtle)`; decorative L-shaped corner brackets via pseudo-elements; optional header slot with a mono index label (`MODULE \u002F\u002F 01`) and blinking status marker.\n- **Hover (interactive cards):** border brightens to `var(--border-default)`, `box-shadow: var(--shadow-md)` glow, `transform: translateY(-2px)`; a scanline sweeps the panel once.\n- **Focus-within:** border and bracket colors highlight when a child link\u002Fbutton receives focus.\n- **Loading (skeleton):** `.is-loading` shimmer animation (gradient sweep) with fixed `min-height`s to prevent layout shift.\n- **Empty state:** `.is-empty` — centered Material Symbol plus short guidance text (\"NO TELEMETRY AVAILABLE\").\n\n**2.3 Form & Input (`.input-group`)** — required in the Final CTA email capture\n- **Structure:** flex-column wrapper (documented `align-items: stretch` exception) containing `\u003Clabel>`, `\u003Cinput type=\"email\">`, and a dedicated error message element with `aria-live=\"polite\"`.\n- **States — all class-driven:** empty; focused (cyan\u002Fblue ring + glow); filled; valid (`.is-valid`: success border + check icon); invalid (`.is-error`: `--border-error`, `--text-error` message + error icon); disabled; read-only. Validation runs in `script.js`; no browser-default styling.\n\n**2.4 Modal \u002F Popup (conditional)**\n- The FAQ **must be an accordion, not modals**. If you introduce any dialog (e.g., pricing plan confirmation), it must: use `\u003Cdialog>` (or `role=\"dialog\"` + `aria-modal=\"true\"`); animate Opening\u002FOpen\u002FClosing states via CSS transitions (opacity + scale); sit in a centered fixed flex overlay (`align-items: center`) with an `rgba(0,0,0,0.8)` backdrop; include a Material Symbols close button; support `Esc` and overlay-click close; trap focus and return it on close; stack at `var(--z-modal)`; support internal loading\u002Fsuccess\u002Ferror feedback.\n\n---\n\n## 3. CORE UX & MICRO-INTERACTION RULES\n\n- **Responsive by default:** fluid `clamp()` typography and spacing; breakpoints at 640\u002F768\u002F1024\u002F1280px; zero horizontal overflow at 320px.\n- **Smooth animations:** every state change transitions with `var(--transition-normal) var(--ease-standard)` (`--transition-fast` for micro-interactions); animate only `transform` and `opacity`.\n- **Mandatory HUD effects:**\n  - **Glow:** `text-shadow: var(--glow-cyan)` on headings\u002Flabels; `box-shadow` glows on key borders.\n  - **Scanning:** a 1px gradient scanline sweeping the hero panel on a 4–6s loop, plus hover-triggered sweeps on interactive panels.\n  - **Ticker:** an infinite horizontal status ticker (duplicated track, `translateX(-50%)` keyframes, `aria-hidden` duplicate copy); pauses on hover\u002Ffocus; renders as static text under reduced motion.\n  - **Blinking markers:** status dots\u002Fsquares pulsing with stepped opacity (e.g., `steps(2)`), always paired with a text label.\n  - **Fine line drawing:** 1px borders throughout, corner brackets, `+` crosshair markers at section edges, and an animated connector line in How It Works that draws in on reveal.\n- **Scroll reveals:** `IntersectionObserver` toggles `.is-visible` (fade + slight translateY, staggered); all content must be fully visible without JS.\n- **Reduced motion:** under `prefers-reduced-motion: reduce`, disable ticker, scan, blink, draw-in, and spinner rotation; keep state changes as instant color\u002Fopacity shifts.\n- **Accessibility (a11y):** AA contrast in both modes; state never conveyed by color alone; semantic landmarks (`header`, `nav`, `main`, `section[aria-labelledby]`, `footer`); a skip-to-content link; logical DOM\u002Ffocus order; full keyboard operability (nav, mobile menu, theme toggle, accordion, form, CTAs); `aria-live` regions for form results and dynamic status; Material icons are `aria-hidden=\"true\"` unless meaningful — then `role=\"img\"` + `aria-label`.\n- **Mandatory visual feedback:** every click, hover, focus, and submission produces a visible response.\n- **Danger styling:** `.btn--danger` and destructive accents remain distinct in both themes.\n- **Performance:** no layout-thrashing animations; throttle JS telemetry updates (~1s); avoid oversized blurs.\n\n---\n\n## 4. DELIVERABLE & OUTPUT FORMAT\n\n- **Files:** exactly `index.html`, `style.css`, `script.js`. One `\u003Cscript src=\"script.js\" defer>\u003C\u002Fscript>` reference only — no inline script blocks, no other scripts.\n- **Naming:** BEM exclusively (`block__element--modifier`), e.g., `.hero__title`, `.hud-panel__index`, `.pricing__tier--featured`. Never mix conventions.\n- **Head:** Google Fonts + Material Symbols links with `preconnect`, `\u003Ctitle>`, meta description, `theme-color` for both modes, `\u003Chtml lang=\"en\">`.\n- **Copy:** all user-facing copy in **English**. Write realistic, on-theme copy for a fictional mission-control\u002Ftelemetry product — invent the product name, feature names, step names, testimonial names\u002Froles, FAQ answers, and prices. No lorem ipsum, no placeholder-only content.\n- No build tools, no CDNs other than Google Fonts\u002FMaterial Symbols; all visuals are CSS-generated (no raster images required).\n\n---\n\n## 5. PAGE SECTION SPECIFICATIONS\n\n**Global chrome**\n- Fixed header (`--z-header`, `rgba(0,0,0,0.8)` + blur with opaque fallback): mono wordmark with bracket decoration; nav links (Features, How It Works, Testimonials, Pricing, FAQ) with animated 1px underline draw on hover\u002Ffocus and smooth-scroll (respecting reduced motion); theme toggle; hamburger on mobile opening a flex-column panel (`aria-expanded`, `Esc` close, focus management, body scroll lock).\n- Fixed HUD frame: 1px corner brackets at all four viewport corners; `pointer-events: none`; `aria-hidden`; hidden below 480px.\n- Page background: fixed grid of 1px `var(--grid-line)` lines (repeating gradients, low opacity) plus a radial vignette; an optional subtle full-page scanline overlay must never obscure text.\n\n**Hero**\n- `min-height: calc(100svh - header height)`; flex column → row at ≥1024px.\n- Left: blinking status marker + mono eyebrow (`SYSTEM v4.2 \u002F\u002F ONLINE`); H1 in `--font-display` with glow on the key phrase; mono subhead in `--text-secondary`; CTA row: `.btn--primary` (\"Initialize System\") + `.btn--ghost` (\"View Specifications\").\n- Right: `.hud-panel` telemetry module — animated counters (nodes, uptime, latency) updated by `script.js`, a CSS-only sparkline\u002Fwaveform (gradients — no images, no chart libraries), sweeping scanline, corner brackets, blinking markers.\n- Below: the ticker strip (e.g., `ALL SYSTEMS NOMINAL \u002F\u002F 12,804 NODES ACTIVE \u002F\u002F UPLINK STABLE \u002F\u002F`).\n\n**Features (3 cards)**\n- Mono section header (`SEC.01 \u002F\u002F CAPABILITIES`) + H2 + one-line intro. Three `.hud-panel`s in a flex-wrap row: bracketed Material Symbol icon, index labels `FEAT_01–03`, title, copy, decorative data bar. Hover lift + glow; staggered scroll reveal.\n\n**How It Works (3 steps)**\n- `SEC.02 \u002F\u002F PROTOCOL`. Three steps with numbered markers (`01 02 03`) inside bracket frames; a 1px connector line between steps — horizontal ≥768px, vertical on mobile — animated draw-in on reveal. Each step: mono label, title, short copy.\n\n**Testimonials**\n- `SEC.03 \u002F\u002F TRANSMISSIONS`. Three quote `.hud-panel`s: quote text, CSS-only avatar (author initials inside a bracket frame — no external images), name + role in mono, and 5 tick markers as a rating. Subtle hover glow.\n\n**Pricing (3 tiers)**\n- `SEC.04 \u002F\u002F ACCESS LEVELS`. Three `.hud-panel` tiers in a flex row (wrap); the middle tier is `.hud-panel--featured` with full `--border-default`, `--shadow-md` glow, and a \"RECOMMENDED\" tag with blinking marker. Each tier: mono name, price in `--font-display` with billing period, feature list using Material `check_circle` (success token) \u002F `close` (error token), and a CTA (`.btn--primary` featured \u002F `.btn--ghost` others). Optional monthly\u002Fannual toggle — if included, it must use `aria-pressed` and animate price changes.\n\n**FAQ**\n- `SEC.05 \u002F\u002F QUERIES`. Accordion of 5 `.faq-item`s: `\u003Cbutton aria-expanded>` question with rotating chevron + answer region (`aria-controls`), animated expansion (grid-rows or max-height technique, no layout jump), fully keyboard operable, real answers.\n\n**Final CTA**\n- `SEC.06 \u002F\u002F INITIALIZE`. Full-width high-impact `.hud-panel` with the strongest theme-appropriate glow treatment: H2, supporting copy, and the `.input-group` email capture + `.btn--primary` (\"Request Access\"). On submit: button enters loading, then simulated success (`.is-success` + `aria-live` status \"ACCESS REQUEST TRANSMITTED\") or inline invalid state — no real network calls.\n\n**Footer with secondary links**\n- Top: four secondary link columns (Product \u002F Company \u002F Resources \u002F Legal) in a flex-wrap layout; mono links with hover underline draw; social icon row (Material Symbols with `aria-label`s); status line `SYS.STATUS: ONLINE` with blinking success marker.\n- Bottom bar: copyright with current year, legal\u002Fsecondary links, back-to-top link.\n\n**`script.js` scope (vanilla, no libraries):** theme init\u002Ftoggle\u002Fpersistence; mobile menu; accordion; IntersectionObserver reveals; form validation + button states; throttled telemetry counters; smooth anchor scrolling; current year. Keep it lean and commented.\n\n---\n\n## 6. DEFINITION OF DONE (self-check before submitting)\n\n1. Zero `style=\"...\"` attributes; zero scripts beyond the single deferred `script.js`.\n2. Both themes render correctly and persist; toggle exposes correct `aria-pressed` \u002F `aria-label`.\n3. All required tokens defined; AA contrast in both modes; no color-only state communication.\n4. Every button\u002Finput\u002Fcard state in Section 2 implemented.\n5. All five signature effects present and disabled under `prefers-reduced-motion`.\n6. Keyboard-only pass: nav, menu, toggle, accordion, form, CTAs all operable with visible focus rings.\n7. No horizontal scroll from 320px to 1440px; documented `align-items` exceptions only.\n8. Consistent BEM naming; all copy in English; no lorem ipsum or placeholder-only content.\n\nDeliver the complete `index.html`, `style.css`, and `script.js` now — first attempt, production quality.\n",1791954992087]
