Build a complete, production-quality landing page on the first attempt. Do not ask clarifying questions — make expert decisions and ship the full build.\n\n---\n\n## 0. PROJECT BRIEF & ART DIRECTION\n\n**0.1 Task**\nA single-page landing site for a fictional Art & Illustration product (invent a plausible brand, e.g., \"Doodlio — the illustration toolkit for sketching ideas fast\"). All user-facing copy is written in **English**, in a friendly, human, approachable voice that matches the sketch aesthetic. No lorem ipsum.\n\n**0.2 Theme**\nHand-Drawn \u002F Sketch (claude-artisan\u002Ftexture, 2016–present). Keywords: doodle, sketchy, hand-illustrated, rough wobbly strokes, sketch-style borders and arrows, marker\u002Fpencil textures, friendly, human, texture. Reference feel: Excalidraw, tldraw, Basecase-style doodle sites.\n\n**0.3 Page Sections (build in this exact order)**\n1. **Sticky Nav** — the theme's `.nav` sketch-card style: brand wordmark in Caveat, anchor links (Features, How It Works, Pricing, FAQ), dark-mode toggle, primary CTA. Collapses to an accessible hamburger panel below 768px.\n2. **Hero** — rotated `.badge`, display `\u003Ch1>` in Caveat with a marker-swipe highlight on the key phrase, subhead, CTA pair (`.btn--primary` + `.btn--secondary`), a small rotated hand-written annotation with a CSS sketch arrow pointing at the CTA, and a CSS-only doodle visual (stacked sketch cards or a rotated Material-icon cluster). No raster images.\n3. **Features** — exactly 3 `.card`s in a responsive grid (1 column mobile → 3 columns desktop): a Material icon inside a rotated sketch-bordered circle, `\u003Ch3>` with marker swipe, friendly copy.\n4. **How It Works** — exactly 3 numbered steps: oversized Caveat numerals inside sketch circles, title + copy, connected by CSS-drawn sketch arrows (pseudo-element strokes with rotated arrowheads, or rotated Material arrow icons). Arrows hide or re-orient vertically on mobile.\n5. **Testimonials** — 3 cards: a Material \"star\" icon row in marker yellow, quote set in Caveat, avatar as a CSS circle with initials (sketch border, slight rotation), name + role in `--text-secondary`.\n6. **Pricing** — 3 tiers; the middle tier is `.card--featured` with a rotated \"Most popular\" `.badge`, stronger shadow, and slight scale\u002Frotation; each tier: name, large Caveat price, feature list with Material \"check\" icons, CTA button (primary on the featured tier, secondary on the others). Optional accessible monthly\u002Fyearly toggle.\n7. **FAQ** — 4–6 accordion items (spec 2.4).\n8. **Final CTA** — full-width band on `--bg-surface-strong`, swipe-highlighted `\u003Ch2>`, email-capture form (spec 2.3) whose submit demonstrates loading → success with toast feedback.\n9. **Footer** — sketch top border, brand blurb, secondary link groups (Product \u002F Company \u002F Support), Material social icons, copyright line. Links use real English labels pointing to page anchors where targets exist.\n\n**0.4 Design Tokens (foundation — extend, never contradict)**\n```css\n\u002F* Hand-Drawn \u002F Sketch — design tokens (light mode) *\u002F\n\u002F* 2016–present | Humanizing counter to sterile flat UI *\u002F\n\u002F* Reference: Hand-Drawn \u002F Sketch flagship implementation spec *\u002F\n:root {\n  \u002F* color — mandatory semantic set *\u002F\n  --bg-primary: #fffdf7;       \u002F* paper cream *\u002F\n  --bg-secondary: #ffffff;     \u002F* card surface (theme-declared) *\u002F\n  --bg-surface-strong: #fff5e0;\n  --text-primary: #2b2b2b;      \u002F* ink *\u002F\n  --text-secondary: #5c5c54;   \u002F* pencil gray *\u002F\n  --primary: #ff6b4a;          \u002F* coral marker *\u002F\n  --secondary: #3b7dd8;       \u002F* ballpoint blue *\u002F\n  --marker: #ffd93b;           \u002F* highlighter yellow *\u002F\n  --text-success: #2f7d32;\n  --text-error: #c62828;\n  --border-default: #2b2b2b;\n  --border-success: #2f7d32;\n  --border-error: #c62828;\n  \u002F* radius: uneven, hand-set radii read as sketchy *\u002F\n  --radius-sm: 6px 9px 7px 10px;\n  --radius-md: 12px 16px 13px 18px;\n  --radius-lg: 22px 28px 24px 30px;\n  --radius-pill: 999px;\n  \u002F* shadow: scratchy pencil offset *\u002F\n  --shadow-sm: 2px 3px 0 rgba(43,43,43,0.5);\n  --shadow-md: 3px 5px 0 rgba(43,43,43,0.4);\n  --shadow-lg: 5px 8px 0 rgba(43,43,43,0.3);\n  \u002F* spacing *\u002F\n  --spacing-gap: 1rem;\n  --space-1: 4px; --space-2: 8px; --space-3: 12px; --space-4: 16px;\n  --space-6: 24px; --space-8: 32px; --space-12: 48px; --space-16: 64px; --space-24: 96px;\n  \u002F* motion *\u002F\n  --transition-fast: 120ms;\n  --transition-normal: 180ms;\n  --ease-standard: cubic-bezier(0.34, 1.56, 0.64, 1);\n  \u002F* stacking *\u002F\n  --z-dropdown: 100; --z-modal: 200; --z-toast: 300;\n  \u002F* type *\u002F\n  --font-base: 'Patrick Hand', 'Comic Neue', 'Segoe Print', sans-serif;\n  --font-display: 'Caveat', 'Kalam', 'Patrick Hand', cursive;\n  --font-mono: 'Courier New', ui-monospace, monospace;\n  --text-xs: 0.8rem; --text-sm: 0.95rem; --text-base: 1.05rem; --text-lg: 1.2rem;\n  --text-xl: 1.5rem; --text-2xl: 1.9rem; --text-3xl: 2.5rem; --text-4xl: 3.4rem; --text-5xl: 4.6rem;\n  \u002F* sketch signature utilities *\u002F\n  --sketch-border: 2px solid var(--border-default);\n  --marker-swipe: linear-gradient(180deg, transparent 55%, var(--marker) 55%, var(--marker) 85%, transparent 85%);\n}\n```\n\n**0.5 Baseline Component CSS (the floor, not the ceiling — Section 2 mandates the full state matrix on top of it)**\n```css\nbody { margin: 0; color: var(--text-primary); font-family: var(--font-base); background: var(--bg-primary); }\n.nav { display: flex; gap: var(--space-4); align-items: center; padding: var(--space-4) var(--space-6);\n  background: var(--bg-secondary); border: var(--sketch-border); border-radius: var(--radius-lg);\n  box-shadow: var(--shadow-sm); margin: var(--space-4); }\n.btn { font: 600 var(--text-base)\u002F1 var(--font-base); color: var(--text-primary);\n  padding: var(--space-3) var(--space-6); border-radius: var(--radius-md);\n  background: var(--bg-secondary); border: var(--sketch-border); box-shadow: var(--shadow-sm);\n  cursor: pointer; transition: transform var(--transition-normal) var(--ease-standard); }\n.btn:hover { transform: rotate(-1deg) translateY(-1px); }\n.btn:active { transform: translate(1px,1px); box-shadow: none; }\n.btn:focus-visible { outline: 3px dashed var(--secondary); outline-offset: 3px; }\n.btn[disabled] { opacity: .5; cursor: not-allowed; }\n.btn--primary { background: var(--primary); color: #2b2b2b; border-color: var(--border-default); }\n.card { background: var(--bg-secondary); border: var(--sketch-border); border-radius: var(--radius-lg);\n  box-shadow: var(--shadow-md); padding: var(--space-6); }\n.card h3 { background-image: var(--marker-swipe); background-repeat: no-repeat; display: inline; }\n.input { width: 100%; box-sizing: border-box; color: var(--text-primary); font: var(--text-base) var(--font-base);\n  padding: var(--space-3) var(--space-4); border-radius: var(--radius-md);\n  background: var(--bg-secondary); border: var(--sketch-border); }\n.input::placeholder { color: var(--text-secondary); }\n.input:focus { outline: none; border-color: var(--secondary); box-shadow: var(--shadow-sm); }\n.badge { display: inline-flex; align-items: center; gap: .4em; font-size: var(--text-xs); font-family: var(--font-display);\n  padding: .3em .9em; border-radius: var(--radius-pill); background: var(--marker);\n  border: var(--sketch-border); transform: rotate(-2deg); }\n```\n**Contrast correction:** the source's `.btn--primary` used light text (`#fffaf0`) on coral, which fails WCAG AA (~2.7:1). Use ink text `#2b2b2b` on coral (~4.9:1), as shown above.\n\n**0.6 Signature Sketch Moves (apply everywhere)**\n- Uneven multi-value border radii on every shaped element; 2px ink borders; scratchy offset shadows.\n- Marker-swipe highlight behind key heading phrases; slight rotations (−1° to −2°) on badges, avatars, and the featured pricing card for a hand-placed feel; wobbly hover transforms with the bouncy `--ease-standard`.\n- **Exception clause:** all doodles, arrows, and textures must be built from CSS (borders, gradients, pseudo-elements) and Google Material Symbols — inline SVG and local icon\u002Fimage files remain forbidden even though the aesthetic invites them.\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 the HTML.\n- All design properties, layout rules, and states are targeted via class or ID selectors only.\n- HTML stays semantic and styling-agnostic: re-theming the site must require editing CSS only, never markup.\n\n**1.2 CSS Variables & Theme Tokens**\n- Every token lives in `:root` (and theme overrides). The mandatory semantic set from 0.4 must exist in full; the theme-specific tokens (`--marker`, `--sketch-border`, `--marker-swipe`, `--space-*`, `--text-*` scale) are retained alongside it.\n- **Contrast pairing:** every light background token pairs with dark text tokens and every dark background token pairs with light text tokens — enforced in every theme, not only the default.\n- The light background is the theme-declared cream `#fffdf7`, never pure white; the theme explicitly declares `--bg-secondary: #ffffff` for card surfaces — retain that declared value, and use `#fefefe` for any additional near-white surface the palette does not cover.\n- When the marker-swipe yellow band sits behind text, the text over the band must be dark ink in both themes (wrap the highlighted phrase accordingly) so contrast never drops below AA.\n\n**1.3 Mandatory Dark Mode Support**\n- The source spec declares no modes and requires validation in light and dark before publishing — therefore a \"charcoal sketchbook\" dark variant must be fully designed, not approximated.\n- Define dark tokens under both `@media (prefers-color-scheme: dark)` and a `.dark` class override. Suggested starting points (validate and adjust to AA): `--bg-primary: #211d18`, `--bg-secondary: #2b2620`, `--bg-surface-strong: #332d24`, `--text-primary: #f7efdd`, `--text-secondary: #b3a892`, `--primary: #ff8a70`, `--secondary: #7fb1f0`, `--border-default: #f0e6d2` (ink strokes flip to light so sketch outlines stay visible), `--marker` unchanged, and shadows re-based on `rgba(0,0,0,0.55)` so the scratchy offset survives on dark paper.\n- Background and text variables must switch seamlessly with zero HTML restructuring.\n- **Persistence:** store the user's choice in `localStorage`; fall back to `prefers-color-scheme` on first visit. Provide a visible toggle in the nav (sun\u002Fmoon Material icons) with correct `aria-pressed` and `aria-label` state, and apply the stored theme as early as possible in `script.js` to avoid a flash of the wrong theme.\n\n**1.4 Flexbox Layout & Mobile-First Alignment**\n- Build all layout structures with Flexbox (Tailwind flex utilities or custom flex classes).\n- Every flex container defaults to `align-items: center` unless an exception is explicitly justified in a CSS comment (e.g., `align-items: stretch` to equalize card-grid heights).\n- Mobile-first: rows become columns on small viewports, nothing overflows horizontally, and all touch targets remain ≥44×44px.\n\n**1.5 Framework Default & Tailwind CSS Integration**\n- Use Tailwind CSS via the Play CDN for structural utilities only (flex, grid, gap, padding, responsive prefixes). Visual identity — color, radius, shadow, borders, fonts — comes exclusively from the CSS variables and the custom component classes in `style.css`.\n- Do not add an inline `tailwind.config` script block; use arbitrary-value utilities referencing `var(...)` instead.\n- All utility usage must map back to the reusable component classes (`.btn`, `.card`, `.input`, `.badge`, `.nav`).\n\n**1.6 Typography & Icons (Google Fonts Mandatory)**\n- Load via Google Fonts: **Patrick Hand** (base, bound to `--font-base`), **Caveat** (display, `--font-display`), with Kalam \u002F Comic Neue as declared fallbacks; the mono stack is for tiny annotations only.\n- Icons: Google Material Symbols (the Rounded variant suits the hand-drawn feel). Raw inline SVGs and local icon files are forbidden; never use emoji as icons.\n- Icons may carry small rotations (≤3°) to read as hand-placed.\n\n---\n\n## 2. COMPONENT DESIGN SPECIFICATIONS\n\n**2.1 Button** — extend the `.btn` baseline to full state coverage, all via CSS classes:\n- **Default:** `display:flex; align-items:center; justify-content:center; gap:0.5rem;` minimum 44×44px touch target; sketch border, uneven radius, scratch shadow.\n- **Variants:** `.btn--primary` (coral background with dark ink text — never light text on coral), `.btn--secondary` (surface background), `.btn--danger` (defined and visually distinct in both themes, even if unused on this page).\n- **Hover:** `rotate(-1deg) translateY(-1px)` plus a shadow shift, `cursor: pointer`.\n- **Focus:** a distinct dashed `--secondary` focus ring (`outline` + offset) for keyboard navigation.\n- **Active:** `translate(1px,1px)` with the shadow removed — pressed into the paper.\n- **Loading (`.is-loading`):** pointer events disabled, double-submit prevented, a CSS spinner (wobbly ink-circle animation) or rotating Material icon, and button dimensions locked so nothing shifts.\n- **Disabled:** `opacity: 0.5`, grayscale, `cursor: not-allowed`.\n- **Success\u002FError (`.is-success` \u002F `.is-error`):** temporary feedback styles driven by `--text-success` \u002F `--text-error`, always paired with an icon and announced via an `aria-live` region.\n\n**2.2 Card** — used by Features, Testimonials, and Pricing:\n- **Default:** flexible flexbox layout, `--bg-secondary` surface, sketch border, uneven `--radius-lg`, `--shadow-md`.\n- **Hover:** `translateY(-2px)` plus `--shadow-lg`; interactive cards may add ≤1° rotation.\n- **Focus-within:** border shifts to `--secondary` and the shadow deepens when any child link\u002Fbutton receives focus.\n- **Loading (skeleton):** define a `.skeleton` shimmer utility (marker-tinted gradient sweep, reduced-motion-safe) in CSS so future dynamic content never causes layout jumps.\n- **Empty state:** define a `.card--empty` fallback pattern — a large Material icon plus one line of guidance text.\n- Card headings use the marker-swipe highlight (`display:inline` background-image).\n\n**2.3 Form & Input** — the Final CTA email capture:\n- **Structure:** a flex `.form-field` wrapper (column on mobile, row on desktop) containing `\u003Clabel>`, `.input`, and a dedicated `.form-error` container; label tied via `for`\u002F`id`; errors linked with `aria-describedby` and `aria-invalid` on the input.\n- **States:** empty, focused (accent border + shadow ring), filled, valid (`.is-valid` — success border + check icon), invalid (`.is-invalid` — error border, error icon, red message text; never color alone), disabled, read-only.\n- Submit runs the full `.btn` loading → success\u002Ferror cycle with feedback in an `aria-live` region and a toast (2.5).\n\n**2.4 FAQ Accordion**\n- Use native `\u003Cdetails>`\u002F`\u003Csummary>` styled to the theme: summary is a flex row (`align-items:center`, gap) with a rotating Material \"expand_more\" chevron, sketch border, uneven radius; animate open\u002Fclose via a CSS grid-rows or max-height technique.\n- Fully keyboard operable, visible focus states, no hidden unreachable content.\n\n**2.5 Toast \u002F Live Feedback**\n- `.toast` fixed bottom-center at `--z-toast`, sketch-card styled, `role=\"status\"` and `aria-live=\"polite\"`, Material icon + message, close button with `aria-label`, auto-dismiss with a reduced-motion-safe transition.\n\n**2.6 Modal**\n- No modal is among the requested sections — do not add one. If one is ever introduced later, it must implement: opening\u002Fopen\u002Floading\u002Fsuccess\u002Fclosing states animated via CSS transitions, a centered flex container, backdrop overlay, Material icon close button, keyboard focus trap, and close via `Esc` or overlay click.\n\n---\n\n## 3. CORE UX & MICRO-INTERACTION RULES\n\n- **Responsive by default:** fluid sizing, breakpoints (~640\u002F768\u002F1024px), grids collapse to one column, nav collapses to hamburger, zero horizontal overflow.\n- **Smooth animations:** every state change transitions with `--transition-normal` and `--ease-standard`; a global `prefers-reduced-motion: reduce` rule disables transforms, animations, and transitions site-wide (replacing the source's button-only rule).\n- **Accessibility:** WCAG AA contrast in both light and dark — validate, don't assume (check coral-on-cream and cream-on-charcoal). Never communicate state by color alone. Semantic HTML5 landmarks (`header`, `nav`, `main`, `section`, `footer`), a single `\u003Ch1>`, logical heading order, a skip-to-content link, logical DOM\u002Ffocus order, full keyboard operability, and correct ARIA on the theme toggle, mobile menu, accordion, and live regions.\n- **Mandatory visual feedback:** every click, hover, and submission produces a visible state change.\n- **Destructive actions:** `.btn--danger` must be visually distinct in both themes.\n- **Copy:** all user-facing copy in English; friendly, human, illustration-flavored; no lorem ipsum and no unrequested placeholder content.\n\n---\n\n## 4. DELIVERABLE & OUTPUT FORMAT\n\n- **Files:** separate `index.html`, `style.css`, and `script.js`. The only permitted `\u003Cscript>` tags are the Tailwind Play CDN reference and a single `\u003Cscript src=\"script.js\" defer>\u003C\u002Fscript>` — no inline script blocks and no inline event handlers (`onclick` etc. are forbidden; bind all listeners in JS).\n- **Naming:** one consistent BEM convention throughout (`.btn`, `.btn--primary`, `.card__title`, `.nav__link`, `.faq__item`, `.pricing__tier`…). The theme's provided class names are the BEM blocks. Never mix conventions.\n- **script.js scope:** theme toggle with `localStorage` persistence, mobile nav, FAQ behavior (if JS-assisted), form validation with loading\u002Fsuccess\u002Ftoast, and optional scroll-reveals (reduced-motion aware; all content must remain visible without JS).\n- **Completion:** ship the complete page on the first attempt, then self-audit both light and dark modes before declaring done.\n",1791954985212]
