Deliver a complete, polished landing page in one pass.\n\n**Art Direction:** \"KEY — a wire to nowhere\" — a 2020s-contemporary tribute to the telegraph key: brass, aged paper, morse dots and dashes, humming wires, long-distance longing. Keywords: morse, telegraph, vintage, nostalgic, animated, gradient. Required effects: **Glow, Neumorphism, Gradients, Micro-animations, Hover Effects.** Techniques: Flexbox, CSS Filters, Keyframe Animations, Transitions, Transforms, Gradients, Box Shadows, Border Radius.\n\n**Sections (in order):** Hero • Features (3 cards) • How It Works (3 steps) • Testimonials • Pricing (3 tiers) • FAQ • Final CTA • Footer with secondary links. Include a minimal sticky header (logo, anchor nav, theme toggle) and a \"Skip to content\" link.\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.**\n* Style exclusively via class\u002FID selectors. HTML must remain clean, semantic, and styling-agnostic — reskinning the page must require CSS edits only, never markup changes.\n\n**1.2 CSS Variables & Theme Tokens**\nDefine all tokens in `:root` (overridden in `.dark`). Required names: `--primary, --secondary, --bg-primary, --bg-secondary, --text-primary, --text-secondary, --text-success, --text-error, --border-default, --border-error, --border-success, --radius-sm, --radius-md, --radius-lg, --shadow-sm, --shadow-md, --spacing-gap, --transition-fast, --transition-normal, --ease-standard, --z-dropdown, --z-modal, --z-toast`.\n\n**Light mode (canonical) — map the given palette:**\n* `--primary: #382715` — the source lists `#38271562` (8-digit hex = dark brown at ~38% alpha). Keep it verbatim as `--primary-veil: #38271562` for translucent overlays, gradient stops, and glow halos; use its solid form for `--primary`.\n* `--secondary \u002F --accent: #e8c98f` (brass key) and `--muted: #8a795c` (weathered ink).\n* `--bg-primary: #e8dcc8` (aged paper) — **never pure white**; use `#fefefe` only if a near-white surface is genuinely needed. `--bg-secondary:` a lighter cream tint derived from the palette for elevated cards.\n* `--text-primary: #241a10`, `--text-secondary: #8a795c`; `--text-success:` patina green, `--text-error:` sealing-wax red — final values must clear 4.5:1 on paper backgrounds. `--border-default`: soft palette-derived brown; `--border-success`\u002F`--border-error` match the text tokens.\n* **Contrast pairing is mandatory in every theme:** light backgrounds pair with dark text; dark surfaces pair with light text (e.g., `#e8dcc8` ↔ `#241a10`\u002F`#170f08`; `#170f08`\u002F`#241a10` ↔ `#e8dcc8`).\n* **Theme-extension tokens (required):** `--gradient-brass` (135° gradient from `#e8c98f` to `#8a795c`), `--gradient-paper`, `--glow-brass` (warm brass box-shadow halo), `--shadow-neu` (dual neumorphic shadow tuned to the paper background), `--font-display`, `--font-base`, `--font-mono`.\n\n**1.3 Mandatory Dark Mode Support**\n* **Exception clause:** the source style spec designates Light as the theme's primary identity (✓ Light \u002F ○ Dark) — light mode is therefore the default, canonical presentation. **Dark mode is still mandatory** and must be fully implemented, not stubbed.\n* Build the \"night telegraph office\": `--bg-primary: #170f08`, `--bg-secondary: #241a10`, `--text-primary: #e8dcc8`, `--text-secondary:` a brightened `#8a795c` tint that clears 4.5:1 on `#170f08`, borders in warm dark browns, brass glow intensified, neumorphic shadows retuned for dark surfaces.\n* Provide tokens under both a `.dark` class and `@media (prefers-color-scheme: dark)`; switching must require zero HTML restructuring.\n* Persist the choice in `localStorage`; first visit falls back to `prefers-color-scheme`, then to light. Visible toggle (Material Symbols `light_mode`\u002F`dark_mode`) with correct `aria-pressed` and dynamic `aria-label` (\"Switch to dark mode\" \u002F \"Switch to light mode\").\n\n**1.4 Flexbox Layout & Mobile-First Alignment**\n* Build every layout with Flexbox. **Every flex container defaults to `align-items: center`** unless an exception is explicitly justified.\n* Mobile-first: all multi-column rows (features, steps, testimonials, pricing, footer) collapse to a single column on small viewports; **no horizontal scrolling at any width from 320px up**.\n\n**1.5 Framework Default & Tailwind CSS Integration**\n* Use Tailwind CSS — or clean custom CSS organized with `@layer`\u002F`@apply`. All utilities must resolve to CSS variables or reusable component classes (`.btn`, `.card`, `.input-group`).\n\n**1.6 Typography & Icons (Google Fonts Mandatory)**\n* Google Fonts only, loaded via `\u003Clink>`\u002F`@import`:\n  * `--font-display: 'Fraunces'` — nostalgic, characterful serif for headings.\n  * `--font-base: 'Libre Franklin'` — readable vintage-flavored body copy.\n  * `--font-mono: 'IBM Plex Mono'` — morse strings, telegraph micro-labels, prices, postmarks.\n* Icons: **Google Material Symbols only**. **Raw inline SVGs and local icon files are forbidden.**\n\n---\n\n## 2. COMPONENT DESIGN SPECIFICATIONS\n\n**2.1 Button Component Requirements** — all states via CSS classes:\n* **Default:** `display: flex; align-items: center; justify-content: center; gap: 0.5rem;` min 44×44px. Variants: `.btn--primary` (brass gradient fill, dark `#241a10` text, subtle glow), `.btn--secondary` (neumorphic pressed-paper button, letterpress text), `.btn--ghost` (text + underline \"wire\").\n* **Hover:** brightness\u002Fshadow shift, brass glow intensification, `cursor: pointer`.\n* **Focus:** distinct focus ring from CSS variables, visible on paper and dark backgrounds.\n* **Active:** `transform: scale(0.97)` — a telegraph key being tapped.\n* **Loading:** disables interaction, blocks double-clicks, shows a CSS spinner or pulsing Material Symbol **without changing button dimensions**.\n* **Disabled:** `opacity: 0.5`, greyscale, `cursor: not-allowed`.\n* **Success\u002FError:** temporary states driven by `--text-success`\u002F`--text-error` (e.g., CTA flips to \"Sent\" with a `check` icon).\n* **Destructive (if any):** `.btn-danger`, visually distinct in both themes.\n\n**2.2 Card Component Requirements** (Features, Testimonials, Pricing):\n* **Default:** flexible flex column, `--bg-secondary` surface, subtle `--border-default` border, neumorphic elevation, `--radius-lg`. Style cards as aged telegram slips with decorative morse dot\u002Fdash rules (pure CSS) and mono postmark micro-labels.\n* **Hover:** `transform: translateY(-2px)` plus shadow\u002Fglow shift.\n* **Focus-within:** border highlights when a child link\u002Fbutton is focused.\n* **Loading (skeleton):** shimmer keyframe in CSS; zero layout jump.\n* **Empty state:** Material Symbol + guidance-text pattern (define even if unused).\n\n**2.3 Form & Input Requirements** (Final CTA email capture):\n* **States:** empty, focused (outline ring), filled, valid (success border + `check_circle`), invalid (error border, `--text-error` message + `error` icon), disabled, read-only.\n* **Structure:** flex `.input-group` wrapping `\u003Clabel>`, `\u003Cinput>`, and a dedicated error-feedback container wired to an `aria-live=\"polite\"` region. Style as a telegram transmission line (mono font, underline).\n\n**2.4 Modal \u002F Popup Requirements (conditional)**\n* If any overlay is introduced (e.g., demo lightbox): Opening → Open → Loading → Success\u002FError → Closing, all CSS-animated; centered flex container (`align-items: center`), backdrop, Material Symbol close button, keyboard focus trap, close on `Esc` and overlay click, `role=\"dialog\"` + `aria-modal`.\n\n**2.5 FAQ Accordion Requirements**\n* Each item: a `\u003Cbutton>` trigger with `aria-expanded`\u002F`aria-controls`, a rotating `expand_more` Material Symbol, and a panel that animates open\u002Fclosed via CSS transitions with no abrupt jumps. Fully keyboard operable; hover\u002Ffocus feedback on triggers.\n\n**2.6 Section-by-Section Build Specification**\n* **Header (sticky):** morse monogram logo (`−·−` for \"K\"), anchor nav (Features, How It Works, Testimonials, Pricing, FAQ), theme toggle, compact `.btn--primary` CTA. On mobile the nav collapses behind a keyboard-accessible menu button. Sections get `scroll-margin-top`; smooth scrolling with a `prefers-reduced-motion` override.\n* **Hero:** oversized Fraunces headline, a decorative mono morse line (`−·− · −·−−` = \"KEY\"), animated gradient backdrop (paper + drifting brass radial glow via keyframed `background-position`), a blinking telegraph indicator dot, and two CTAs: `.btn--primary` \"Send the First Message\" (scrolls to Final CTA) and `.btn--secondary` \"Read the Wire\" (scrolls to Features). Optional pure-CSS telegraph-key silhouette built from gradients, filters, and border-radius — no images, no SVG.\n* **Features (3 cards):** each with a Material Symbol in a neumorphic brass-wash circle, a title, 2–3 lines of copy, and a mono micro-label (e.g., `MSG 01 — STOP`). Suggested angles (write original English copy in the same voice): 1) The Wire — instant transmission; 2) The Key — tactile, deliberate sending; 3) The Silence — quiet, human, ad-free.\n* **How It Works (3 steps):** steps \"Tap the Key → Ride the Wire → Arrive Somewhere,\" connected by a CSS gradient \"wire\" with an animated traveling pulse dot; the wire becomes vertical on mobile.\n* **Testimonials:** 3 telegram-styled quote cards: mono quote block with `— STOP` separators, initials-monogram avatar inside a neumorphic circle (no external images), name + role, Material Symbol star rating with an accessible text label (never color\u002Ficon alone).\n* **Pricing (3 tiers):** \"Local Wire\" (free), \"Long Distance\" (featured — brass gradient border, glow, mono \"MOST POPULAR\" badge), \"Continental\" (premium). Each card: tier name, mono price, feature list with Material Symbol checks, per-tier CTA (featured uses `.btn--primary`, others `.btn--secondary`). Optionally add an accessible monthly\u002Fannual switch (`role=\"switch\"`, `aria-checked`) — only if implemented cleanly.\n* **FAQ:** 4–6 themed questions using the 2.5 accordion.\n* **Final CTA:** full-width animated-gradient panel with brass glow, short poetic headline, the 2.3 email form with a Loading → Success button state (\"Message sent — the wire hums.\"), inline `aria-live` feedback, and decorative morse.\n* **Footer with secondary links:** dark-token inversion (bg `#170f08`, text `#e8dcc8` — contrast-paired; adapts via tokens in dark mode). Columns: Product anchors, Company, Resources, and social links (Material Symbols) — every secondary link must resolve to a real anchor or themed destination, no dead `href=\"#\"`. Legal bar with © line and a morse sign-off.\n\n---\n\n## 3. CORE UX & MICRO-INTERACTION RULES\n\n* **Responsive by default:** fluid type via `clamp()`; no horizontal overflow from 320px up.\n* **Smooth animations:** transition on all state changes with `var(--transition-normal)`. Required keyframes: `pulse` (breathing morse dot), `travel` (wire current), `shimmer` (skeleton), `blink` (telegraph indicator), `gradient-shift` (hero backdrop). All motion is disabled under `prefers-reduced-motion: reduce` with graceful static fallbacks.\n* **Accessibility (a11y):** ≥4.5:1 body-text contrast in **both** modes; never color alone to communicate state; semantic HTML5 (`header\u002Fmain\u002Fsection\u002Fnav\u002Ffooter`, logical `h1`→`h2` order); ARIA roles\u002Flabels on the theme toggle, accordion, and any switch; logical DOM\u002Ffocus order; full keyboard operability; `aria-live` regions for form errors, success feedback, and loading states; visible \"Skip to content\" link.\n* **Mandatory visual feedback:** every click, hover, focus, and submission triggers a visible state change.\n* **Effects discipline:** glow halos, neumorphic press states, drifting gradients, hover lift, tap-down scale — but glow and gradients must never reduce text contrast or cover interactive targets. Layer stacked UI with `--z-dropdown` (mobile menu), `--z-modal` (any dialog), `--z-toast` (any success toast).\n\n---\n\n## 4. DELIVERABLE & OUTPUT FORMAT\n\n* **Files:** separate `index.html`, `style.css`, and `script.js`. No inline styles; no inline `\u003Cscript>` blocks beyond the single deferred `script.js` reference; no inline SVGs; no external or local image assets — build all visuals from CSS, gradients, filters, Material Symbols, and typography.\n* **Naming convention (single, consistent):** BEM for custom component classes (`.btn`, `.btn--primary`, `.card__title`, `.faq__trigger`) authored in `style.css` (via `@layer components` if using Tailwind), with Tailwind utilities reserved strictly for layout\u002Fspacing. Never mix in ad-hoc class names.\n* **Copy:** write all user-facing copy in English, in the wistful telegraph voice. **No lorem ipsum** — invent coherent, on-theme content for every section, label, and link.\n* **Acceptance:** the page must be complete, polished, and production-ready on the first attempt — every section, every interactive state (default \u002F hover \u002F focus \u002F active \u002F loading \u002F disabled \u002F valid \u002F invalid \u002F open \u002F closed), both light and dark themes, and reduced-motion behavior all functional.\n",1791954993120]
