[{"data":1,"prerenderedAt":4},["ShallowReactive",2],{"prompt-743-Terra-Incognita":3},"# SYSTEM PROMPT — Build the \"Terra Incognita\" Landing Page (Complete, First Attempt)\n\n**Role:** You are a Senior Frontend Engineer and Expert UI Designer. Build a complete, production-ready landing page in a single pass. No partial output, no follow-up questions, no truncation, no TODOs.\n\n**Project Brief:**\n\n* **Theme:** *Terra Incognita* — an artistic\u002Fcreative cartography & atlas aesthetic: aged parchment maps, compass roses, contour lines, latitude\u002Flongitude grids, ink-and-cream exploration mood, executed with 2020s contemporary polish.\n* **Sections (in order):** Sticky Header\u002FNav → Hero → Features (3 cards) → How It Works (3 steps) → Testimonials → Pricing (3 tiers) → FAQ → Final CTA (email capture) → Footer with secondary link columns.\n* **Palette (given):** Primary `#20180f`, `#2b2115`, `#3a2c1a`; Secondary `#211709`, `#5c3a1e`, `#e8d9b8`.\n* **Visual Effects (given):** Glow, Neumorphism, Gradients, Hover Effects.\n* **CSS Techniques (given):** CSS Grid, Flexbox, Keyframe Animations, Transitions, Transforms, Gradients, Box Shadows, Text Shadows, Border Radius.\n* **Mode (given):** Light-first presentation (Dark mode is still mandatory — see §1.3 exception).\n* **Language:** All user-facing copy, labels, comments, class names, variables, and file names in English.\n\n---\n\n## 1. STRICT RULES & ARCHITECTURE\n\n**1.1 CSS-First Architecture & Zero Inline CSS**\n\n* All styling lives exclusively in `style.css`. The `style=\"...\"` attribute is **forbidden** anywhere in the HTML.\n* Target all design properties, layout rules, and states via class or ID selectors only.\n* HTML must remain clean, semantic, and style-agnostic: re-theming the site must require editing `style.css` only, never the markup.\n\n**1.2 CSS Variables & Theme Tokens**\n\nStore every visual token in `:root` (light\u002Fdefault) and override in `.dark` (see §1.3). Required tokens:\n\n* **Colors:** `--primary`, `--secondary`, `--bg-primary`, `--bg-secondary`, `--text-primary`, `--text-secondary`, `--text-success`, `--text-error`, `--border-default`, `--border-error`, `--border-success`. You may add supporting tokens (e.g., `--accent-parchment`, `--glow`).\n* **Suggested light values:** `--primary: #20180f`; `--secondary: #5c3a1e`; `--accent-parchment: #e8d9b8`; `--bg-primary: #f3ecdb` (warm parchment — never pure white; use `#fefefe` only if a near-white surface is genuinely required); `--bg-secondary: #faf5e7` (elevated cards); `--text-primary: #20180f`; `--text-secondary: #5c3a1e`; `--text-success: #3e6b35`; `--text-error: #a63d2a` (cartographic red ink); `--border-default: #d8c8a6`.\n* **Suggested dark values:** `--bg-primary: #20180f`; `--bg-secondary: #2b2115`; `--text-primary: #e8d9b8`; `--text-secondary: #c9b489`; `--border-default: #3a2c1a`; success\u002Ferror shifted to lighter variants (e.g., `#a8c98e`, `#e08a70`) for dark-mode contrast.\n* **Contrast pairing is mandatory in every theme:** any light background token pairs with a dark text token; any dark background token pairs with a light text token. Verify ≥ 4.5:1 contrast for body text in **both** modes.\n* **Radius & shadows:** `--radius-sm: 8px`, `--radius-md: 16px`, `--radius-lg: 24px`, `--shadow-sm`, `--shadow-md`. Define neumorphic dual shadows (one dark, one light offset shadow per surface) per theme, and a warm `--glow` token (e.g., light mode: `0 0 24px rgba(92,58,30,0.25)`; dark mode: `0 0 24px rgba(232,217,184,0.35)`).\n* **Spacing & transitions:** `--spacing-gap`, `--transition-fast: 150ms`, `--transition-normal: 300ms`, `--ease-standard: cubic-bezier(0.4, 0, 0.2, 1)`.\n* **Elevation:** `--z-dropdown`, `--z-modal`, `--z-toast` — sticky header uses `--z-dropdown`; never hard-code z-index values.\n\n**1.3 Mandatory Dark Mode Support**\n\n* Dark mode **must always be fully defined**: all required tokens overridden under a `.dark` class selector applied to `\u003Chtml>`, so backgrounds and text swap seamlessly with zero HTML restructuring.\n* Provide a visible theme toggle in the header (sun\u002Fmoon Google Icons) with correct `aria-pressed` and a dynamically updated `aria-label` (\"Switch to dark mode\" \u002F \"Switch to light mode\"); it must be keyboard operable and cause no layout shift.\n* Persist the user's explicit choice via `localStorage`.\n* **Exception (user-specified Light-first build):** Light mode is the required default presentation — on first visit (no `localStorage` value), render Light mode and do **not** auto-apply a bare `@media (prefers-color-scheme: dark)` block that would override the Light default; dark mode applies exclusively via the `.dark` class. All other dark-mode obligations above remain fully in force.\n* Dark mode must stay on-theme: espresso-ink backgrounds (`#20180f`, `#2b2115`), parchment-cream text, and glow\u002Fneumorphic effects re-tuned to remain visible on dark surfaces.\n\n**1.4 Flexbox & CSS Grid Layout (Mobile-First)**\n\n* Use **CSS Grid** for macro layouts: Features (3 cards), How It Works (3 steps), Testimonials, Pricing (3 tiers), and Footer columns — e.g., `grid-template-columns: repeat(auto-fit, minmax(260px, 1fr))`.\n* Use **Flexbox** for all component internals (buttons, nav, card content, form rows, hero content). Every flex container must default to `align-items: center` unless an exception is explicitly justified in a CSS comment.\n* Mobile-first and responsive by default: all grids collapse to one column below ~768px; the nav collapses to an accessible hamburger panel; no horizontal scrolling at any viewport ≥ 320px.\n\n**1.5 CSS Approach & Reusable Classes**\n\n* Because the style spec enumerates raw CSS techniques, write clean, hand-organized custom CSS in `style.css` structured with `@layer` (tokens → base → components → utilities). If you introduce any Tailwind-style utilities, every utility must map back to the CSS variables or generic reusable classes.\n* Define reusable components as generic classes: `.btn`, `.btn--primary`, `.btn--secondary`, `.btn--danger`, `.card`, `.input-group`, `.section`, `.container`, `.accordion__item`, etc.\n\n**1.6 Typography & Icons (Google Fonts Mandatory)**\n\n* **Text fonts (Google Fonts only):** Fraunces (display\u002Fheadings — its vintage-serif character fits the atlas mood) and Inter (body). Load via `\u003Clink>` tags and bind them to tokens: `--font-display: 'Fraunces', serif` and `--font-base: 'Inter', sans-serif`. Apply fluid sizing with `clamp()`.\n* **Icons:** Google Material Symbols (Outlined) only. Suggested glyphs: `explore`, `travel_explore`, `map`, `terrain`, `layers`, `navigation`, `route`, `auto_stories`, `workspace_premium`, `check_circle`, `expand_more`, `arrow_forward`, `close`, `menu`, `mail`, `alternate_email`, `light_mode`, `dark_mode`.\n* **Raw inline SVGs, local icon files, and emoji-as-icons are explicitly forbidden.**\n\n---\n\n## 2. COMPONENT DESIGN SPECIFICATIONS\n\n**2.1 Button Component**\n\nStyle all states via CSS classes; never inline:\n\n* **Default:** `display: flex; align-items: center; justify-content: center; gap: 0.5rem;` — minimum touch target 44×44px.\n* **Primary variant:** ink `--primary` background with `--accent-parchment`\u002Fcream text and the warm `--glow` on hover.\n* **Secondary variant:** outlined\u002Fghost on parchment with `--secondary` border.\n* **Hover:** brightness shift and\u002For glow intensification with `cursor: pointer`.\n* **Focus-visible:** distinct ring built from CSS variables (`outline` + `box-shadow`) for keyboard navigation.\n* **Active\u002Fpressed:** `transform: scale(0.97)`.\n* **Loading:** disables interaction (prevents double-clicks), preserves button dimensions, renders a CSS-animated spinner or rotating Google Icon; set `aria-busy=\"true\"` via JS.\n* **Disabled:** `opacity: 0.5`, greyscale, `cursor: not-allowed`.\n* **Success\u002FError:** temporary feedback styling driven by `--text-success` \u002F `--text-error` (used by the Final CTA form submit flow).\n* **Danger:** define `.btn--danger` in the stylesheet with visually distinct styling that holds up in both light and dark themes, even if unused on this page.\n\n**2.2 Card Component** (Features, How It Works steps, Testimonials, Pricing tiers)\n\n* **Default:** Grid\u002FFlexbox layout, `--bg-secondary` surface, visible `--border-default`, neumorphic `--shadow-sm` (keep visible borders — never delineate interactive cards by soft shadows alone).\n* **Hover:** `transform: translateY(-2px)` plus a shadow\u002Fglow shift.\n* **Focus-within:** border highlights when a child link\u002Fbutton receives focus.\n* **Loading (skeleton):** define a shimmer keyframe animation and skeleton classes; apply them to any asynchronously rendered content (e.g., a simulated content fetch) without layout jumps.\n* **Empty state:** structured fallback layout (Material Symbol + guidance text) defined in the stylesheet for any dynamic region that can render empty.\n\n**2.3 Form & Input Requirements** (Final CTA email capture; optional footer newsletter)\n\n* **Structure:** Flex container wrapping a `\u003Clabel>`, the input field, and a dedicated error-feedback element with `aria-live=\"polite\"`.\n* **States (all styled in CSS):** Empty, Focused (outline ring via tokens), Filled, Valid (success border + `check_circle` icon), Invalid (error border + error icon + error text — never color alone), Disabled, Read-only.\n* **Behavior (in `script.js`):** validate on blur and on submit (required + email pattern); toggle `aria-invalid`; on submit show the button's loading state, then render a success message into the `aria-live` region (simulated with `setTimeout` — comment clearly that no backend exists).\n\n**2.4 Modal \u002F Popup Requirements** (if any modal is used, e.g., \"View full plan details\" from a pricing tier)\n\n* **States:** Opening, Open, Loading, Success\u002FError, Closing — all animated via CSS transitions.\n* **UX:** centered flex overlay (`align-items: center`) with backdrop, Material Symbol close button, focus trapping, close via `Esc` and overlay click, `role=\"dialog\"` + `aria-modal`, focus restored to the trigger on close, layered via `--z-modal` (any toast uses `--z-toast`). If you ship no modal, the z-index tokens must still be defined.\n\n**2.5 FAQ Accordion**\n\n* Each item: a heading containing a `\u003Cbutton>` with `aria-expanded` + `aria-controls`, controlling a region with `aria-labelledby`.\n* Toggle via click and keyboard (Enter\u002FSpace); animate open\u002Fclose height with the `grid-template-rows: 0fr → 1fr` technique (no `max-height` hacks); rotate the `expand_more` chevron; visible focus ring on the toggle; animations respect `prefers-reduced-motion`.\n\n**2.6 Landing Page Section Composition**\n\n* **Header (sticky, `--z-dropdown`):** brand (compass `explore` icon + \"Terra Incognita\" wordmark in Fraunces), anchor nav links (Features, How It Works, Testimonials, Pricing, FAQ) with animated underline hover, theme toggle, primary CTA. On mobile: hamburger button (`aria-expanded`, `aria-controls`) toggling a slide-down panel; header gains a solid\u002Fblurred backdrop on scroll.\n* **Hero:** ~90vh centered composition over a layered background — a warm gradient blending `#3a2c1a → #5c3a1e → cream wash`, a contour-line\u002Flatitude-grid effect built from repeating gradients, and a slow keyframe glow pulse. Include a slowly rotating compass-rose Material Symbol (keyframe rotation), an eyebrow label, a Fraunces `\u003Ch1>` with a subtle glow `text-shadow`, supporting copy, two CTAs (primary \"Begin the Expedition\"; secondary \"Explore the Atlas\" that smooth-scrolls to Features), and a bouncing scroll cue. Pause all hero animation under reduced motion.\n* **Features:** eyebrow + `\u003Ch2>` + lede heading pattern; 3-card grid; each card: Material Symbol icon (e.g., `travel_explore`, `terrain`, `layers`), Fraunces title, copy; card hover\u002Ffocus-within per §2.2.\n* **How It Works:** 3-step grid with large Fraunces numerals (01\u002F02\u002F03), step icons, titles, copy; a dashed connector line drawn with a CSS pseudo-element between steps, becoming a vertical connector when stacked on mobile.\n* **Testimonials:** 3 quote cards; neumorphic medallion avatars built from styled initials (no external images); quote, name, and role in thematic English copy.\n* **Pricing:** 3 tiers (e.g., Surveyor \u002F Cartographer \u002F Expedition); the middle tier is highlighted via a \"Most Popular\" badge + stronger border + slight scale\u002Felevation — distinction must not rely on color alone; feature lists with `check_circle` icons; one CTA button per tier using full button states; static \"per month\" pricing with a small disclaimer line.\n* **FAQ:** 5–6 themed Q&As using the §2.5 accordion.\n* **Final CTA:** full-width gradient panel (ink → umber → cream glow), Fraunces headline, copy, and the §2.3 email-capture form with a \"Join the Expedition\" submit button demonstrating loading → success\u002Ferror states.\n* **Footer (secondary links):** multi-column grid — brand + tagline; Explore links (Features, Pricing, FAQ anchors); Company links (About, Journal, Careers, Contact); Legal links (Privacy, Terms, Sitemap); bottom bar with © line and Material Symbol contact\u002Fsocial glyphs; include an accessible back-to-top control that appears on scroll.\n\n---\n\n## 3. CORE UX & MICRO-INTERACTION RULES\n\n* **Responsive by default:** fluid type and spacing, no horizontal overflow, touch targets ≥ 44px, `scroll-margin-top` on anchored sections to offset the sticky header.\n* **Smooth animations:** CSS transitions on all state changes using `transition: var(--transition-normal)`. Keyframes required: compass rotation, glow pulse, gradient drift, skeleton shimmer, scroll-cue bounce. Wrap all motion in `@media (prefers-reduced-motion: reduce)` — reduce to opacity-only or none, and disable smooth scrolling.\n* **Accessibility (a11y):** skip-to-content link; semantic HTML5 landmarks (`header`, `nav`, `main`, `section` with `aria-labelledby`, `footer`); exactly one `\u003Ch1>` with logical heading order; `aria-current=\"true\"` on active nav state; ≥ 4.5:1 text contrast in both modes; never rely on color alone to communicate state; full keyboard operability with logical focus order; `aria-live` regions for dynamic feedback (form errors, toasts, loading).\n* **Mandatory visual feedback:** every click, hover, focus, and submission must trigger a visible state change — nav underlines, card lifts, button state shifts, accordion motion, form validation feedback.\n* **Destructive actions:** `.btn--danger` must be visually distinct in both light and dark themes.\n* **Scroll-reveal animations (optional):** if used, implement via `IntersectionObserver` in `script.js`, fully disabled under reduced motion.\n\n---\n\n## 4. DELIVERABLE & OUTPUT FORMAT\n\n* **Files:** `index.html`, `style.css`, `script.js` — separate and complete. No inline styles anywhere; no inline `\u003Cscript>` blocks beyond the single deferred entry-point reference to `script.js`.\n* **Naming convention:** BEM only (`.card`, `.card__title`, `.btn--primary`, `.pricing-card--featured`, `.accordion__item`) — never mix conventions. Section IDs in ASCII English (`#features`, `#how-it-works`, `#pricing`, `#faq`) for nav anchors.\n* **Copy:** no lorem ipsum. The user supplied no final copy, so write coherent, on-theme English marketing copy in an exploration\u002Fcartography voice for every headline, card, step, testimonial (realistic names and roles), pricing tier, and FAQ answer. Real labels and buttons everywhere; placeholders only where content is genuinely unknowable.\n* **Comments:** brief English comments in `style.css` marking token blocks and component groups; in `script.js` explaining the theme toggle, accordion, mobile menu, and form-validation logic.\n* **First-attempt completeness:** output all three files fully written, end to end — no truncation, no \"rest of the code,\" no unfinished sections.\n\n**Definition of Done:** light\u002Fdark themes fully token-driven with a persisting, accessible toggle; zero inline styles; Google Fonts + Material Symbols only; all specified component states present; all 8 sections complete with themed copy; keyboard operable throughout; reduced-motion respected; no horizontal scroll at any width.\n",1791954992072]
