Build a complete, production-quality Landing Page on the first attempt — no partial output, no follow-up questions.\n\n**Objective:** Create a single-page Landing Page in the **\"Studygram \u002F Notebook Kawaii\"** theme: a cute, organized, pastel, educational aesthetic built on notebook paper, felt-tip ink, highlighter markers, doodles, and journaling culture. Required sections: **Hero, Features (3 cards), How It Works (3 steps), Testimonials, Pricing (3 tiers), FAQ, Final CTA, Footer with secondary links**, plus a minimal sticky header for anchor navigation and the theme toggle. Write all user-facing copy in English, in an on-theme studygram\u002Fjournaling voice — real copy, never lorem ipsum.\n\n---\n\n## 1. Theme Design Direction — Studygram \u002F Notebook Kawaii\n\n**1.1 Design Language**\n- Warm notebook-paper background with CSS ruled lines, hand-drawn ink borders, highlighter marker effects, sticker-style components, doodle decorations (hearts, stars, sparkles), and one character mascot. Flat, ambient, personal — no heavy glows or 3D effects.\n\n**1.2 Color Tokens (define exactly in `:root`)**\n```css\n:root {\n  \u002F* Palette *\u002F\n  --primary: #6FA3D2;          \u002F* Soft Blue — fills, borders, decorative *\u002F\n  --primary-ink: #3E6B99;      \u002F* Darkened blue for text\u002Flinks on light bg (WCAG AA) *\u002F\n  --secondary: #FF9EC6;        \u002F* Pink Highlight — decorative, badges, washi tape *\u002F\n  --bg-primary: #F4F2E9;       \u002F* Warm Paper *\u002F\n  --bg-secondary: #FBFAF3;     \u002F* Card paper — near-white, never #ffffff *\u002F\n  --text-primary: #2B2B2B;     \u002F* Dark felt-tip ink *\u002F\n  --text-secondary: #8D6E54;   \u002F* Brown ink *\u002F\n  --highlight-yellow: #F2E66B;\n  --highlight-pink: #FF9EC6;\n  --marker-yellow: rgba(242, 230, 107, 0.55);  \u002F* marker transparency *\u002F\n  --marker-pink: rgba(255, 158, 198, 0.45);\n  --ink-on-fill: #2B2B2B;      \u002F* text on pastel fills — does NOT flip in dark mode *\u002F\n  --text-success: #2E7D4F;\n  --text-error: #B3261E;\n  --border-default: #2B2B2B;   \u002F* hand-drawn ink outline *\u002F\n  --border-error: #B3261E;\n  --border-success: #2E7D4F;\n  \u002F* Shape & depth — wobbly hand-drawn radii *\u002F\n  --radius-sm: 125px 10px 120px 10px \u002F 10px 120px 10px 120px;\n  --radius-md: 255px 15px 225px 15px \u002F 15px 225px 15px 255px;\n  --radius-lg: 375px 25px 335px 25px \u002F 25px 335px 25px 375px;\n  --shadow-sm: 2px 3px 0 rgba(43, 43, 43, 0.12);\n  --shadow-md: 4px 6px 0 rgba(43, 43, 43, 0.16);\n  \u002F* Spacing, motion, stacking *\u002F\n  --spacing-gap: 1.5rem;\n  --transition-fast: 150ms;\n  --transition-normal: 300ms;\n  --ease-standard: cubic-bezier(0.34, 1.56, 0.64, 1); \u002F* sticker overshoot *\u002F\n  --z-dropdown: 100;\n  --z-modal: 1000;\n  --z-toast: 1100;\n  \u002F* Typography *\u002F\n  --font-hand: 'Patrick Hand', 'Comic Sans MS', cursive;  \u002F* headings, doodle numerals *\u002F\n  --font-base: 'Quicksand', 'Trebuchet MS', sans-serif;  \u002F* body copy *\u002F\n}\n```\n- **Contrast pairing rule:** every light background token pairs with dark text tokens and every dark background token pairs with light text tokens — enforced in both themes. Never use `--secondary` (pink) or `--highlight-yellow` as text color on light backgrounds; they are decorative fills behind `--text-primary` ink only. Pastel-filled elements (`--primary`, `--secondary`, highlights) always carry dark ink text in both themes via `--ink-on-fill`. Where blue text is needed on light backgrounds, use `--primary-ink`, never `--primary`.\n\n**1.3 Notebook Paper Background (CSS-only)**\n- Ruled-paper effect via `repeating-linear-gradient` (1px line every ~32px in a soft blue or brown-ink tint) layered over `--bg-primary`, plus an optional vertical pink margin line via a fixed pseudo-element. Expose as reusable classes (`.paper`, `.paper--ruled`). No image files.\n\n**1.4 Signature Effects (all CSS; all gated behind `prefers-reduced-motion`)**\n- **Highlighter swipe:** `.highlight` \u002F `.highlight--pink` — `background-image: linear-gradient(var(--marker-yellow), var(--marker-yellow)); background-repeat: no-repeat; background-size: 0% 45%; background-position: 0 65%;` animating to `100% 45%` on hover or scroll-reveal via `transition: background-size var(--transition-normal)`.\n- **Hand-drawn wobble:** subtle `@keyframes wobble` (±0.5deg rotation) on stickers, mascot, and badges — on hover or as a slow idle animation.\n- **Sticker pop-in:** `@keyframes pop-in` (scale 0.6 + rotate −6deg → overshoot 1.05 → settle) using `--ease-standard`, triggered by an `.is-visible` class added via IntersectionObserver.\n- **Doodle reveal on scroll:** decorative doodles fade\u002Fdraw in as sections enter the viewport (IntersectionObserver + CSS transitions).\n- **Ambient scanning light:** a slow, flat, translucent gradient sheen sweeping across the hero via a keyframed pseudo-element — subtle, no glow.\n- **Hand-drawn borders:** primary technique is the wobbly `border-radius` tokens above with `2px solid var(--border-default)`; vary which radius token each component uses so outlines feel organically imperfect.\n\n**1.5 Icons, Doodles & Mascot — Google Fonts\u002FIcons Mandatory**\n- Load **Google Fonts** (`Patrick Hand` + `Quicksand`) and **Google Material Symbols Rounded** via `\u003Clink>` tags with `preconnect`.\n- All functional icons must be Material Symbols (e.g., `favorite`, `star`, `auto_awesome`, `menu_book`, `sticky_note_2`, `edit`, `check_circle`, `cancel`, `expand_more`, `dark_mode`, `light_mode`, `close`, `menu`).\n- **Inline SVG exception clause:** raw inline SVG remains forbidden for icons; the single explicit exception is decorative hand-drawn artwork — wobbly border shapes, doodle illustrations, and the character mascot — which may use inline SVG because this theme's hand-drawn aesthetic cannot be reproduced with icon fonts. Every such SVG must be purely decorative (`aria-hidden=\"true\"`, `focusable=\"false\"`), carry no information, and be styled exclusively through CSS classes — never a `style` attribute.\n\n---\n\n## 2. Strict Rules & Architecture\n\n**2.1 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 applied via class\u002FID selectors only.\n- HTML stays clean, semantic, and style-agnostic: changing the site's look must require editing only `style.css`, never the markup.\n\n**2.2 CSS Variables & Theme Tokens**\n- Every component consumes the tokens from 1.2 via `var(...)`. No hard-coded hex values outside `:root` and the dark-mode block.\n\n**2.3 Mandatory Dark Mode — \"Midnight Notebook\"**\n- Define a full dark theme under both `@media (prefers-color-scheme: dark)` and a `.dark` class, remapping tokens:\n```css\n.dark {\n  --bg-primary: #23211B;      \u002F* dark kraft paper *\u002F\n  --bg-secondary: #2B2822;\n  --text-primary: #F4F2E9;\n  --text-secondary: #C9BFAE;\n  --primary: #8FBCE6;\n  --primary-ink: #A8CCEC;\n  --secondary: #FFB3D1;\n  --marker-yellow: rgba(242, 230, 107, 0.30);\n  --marker-pink: rgba(255, 158, 198, 0.28);\n  --text-success: #7FD6A0;\n  --text-error: #FF9E8E;\n  --border-default: #F4F2E9;  \u002F* ink outline becomes light *\u002F\n  --border-error: #FF9E8E;\n  --border-success: #7FD6A0;\n  --shadow-sm: 2px 3px 0 rgba(0, 0, 0, 0.4);\n  --shadow-md: 4px 6px 0 rgba(0, 0, 0, 0.5);\n}\n```\n- Ruled lines and marker effects must be re-tinted for dark mode (translucent, lighter) so ink text stays readable. Background and text variables must switch seamlessly with zero HTML restructuring.\n- **Theme toggle:** a visible header button using Material Symbols (`dark_mode` \u002F `light_mode`) with correct `aria-pressed` and a dynamic `aria-label` (\"Switch to dark mode\" \u002F \"Switch to light mode\").\n- **Persistence:** store the choice in `localStorage` (e.g., key `studygram-theme`); first visit falls back to `prefers-color-scheme`. The only permitted inline script is an optional one-line bootstrap in `\u003Chead>` that applies the stored theme class before first paint to avoid a flash — nothing else may be inline.\n\n**2.4 Flexbox Layout & Mobile-First Alignment**\n- Build all layout structures with Flexbox. Every flex container defaults to `align-items: center` unless an exception is explicitly justified in a CSS comment.\n- Mobile-first: multi-column rows (features, steps, pricing, footer columns) collapse to a single column on small viewports and re-flow via `flex-wrap`. No horizontal scrolling at any width; use fluid `clamp()` typography.\n\n**2.5 Framework & Naming**\n- No external CSS framework: write clean custom CSS organized in native cascade layers — `@layer tokens, base, layout, components, utilities;` — in that order.\n- One naming convention everywhere: **BEM** (`.card`, `.card__title`, `.card--featured`, `.btn--primary`). Never mix conventions. Generic reusable classes (`.btn`, `.card`, `.input-group`, `.container`, `.section`) drive the design system.\n\n**2.6 Typography & Icons**\n- `--font-hand` for the H1, section titles, sticker badges, doodle numerals, and testimonial quotes; `--font-base` for all body copy, buttons, forms, and footer — readability first.\n\n---\n\n## 3. Component Design Specifications\n\n**3.1 Buttons — `.btn` with variants `.btn--primary`, `.btn--secondary`, `.btn--accent`, `.btn--danger`**\n- **Default:** `display: flex; align-items: center; justify-content: center; gap: 0.5rem;` minimum touch target 44×44px; wobbly `--radius-md`; `2px solid var(--border-default)`. Primary = `--primary` fill + `--ink-on-fill` text; secondary = `--bg-secondary` fill + ink border; accent = `--secondary` fill + `--ink-on-fill` text; `.btn--danger` must be visually distinct in both themes (error-red fill\u002Fborder + icon).\n- **Hover:** brightness shift + `--shadow-sm` lift + playful `rotate(-1deg)`; `cursor: pointer`.\n- **Focus:** always-visible hand-drawn ring: `outline: 2px dashed var(--primary-ink); outline-offset: 3px;` — never remove it.\n- **Active\u002FPressed:** `transform: scale(0.97)`.\n- **Loading (`.is-loading`):** pointer-events disabled (prevents double-clicks\u002Fdouble submits), CSS border spinner or rotating Material Symbol, and the button's exact dimensions preserved (no layout shift).\n- **Disabled:** `opacity: 0.5; filter: grayscale(1); cursor: not-allowed;`\n- **Success\u002FError feedback (`.is-success` \u002F `.is-error`):** temporary submit feedback driven by `--text-success` \u002F `--text-error`, always paired with an icon and\u002For text — never color alone.\n\n**3.2 Cards — `.card` (Features, Testimonials, Pricing)**\n- **Default:** flexbox column layout on `--bg-secondary`, wobbly `--radius-md`, 2px ink border, `--shadow-sm`; optional washi-tape strip (rotated translucent pastel pseudo-element) and sticker badge.\n- **Hover:** `transform: translateY(-2px)` + `--shadow-md` (+ optional 0.5deg tilt).\n- **Focus-within:** border shifts to `--primary` when a child link\u002Fbutton receives focus.\n- **Loading skeleton (`.card--skeleton`):** shimmer keyframe (translucent gradient sweep) with reserved dimensions to prevent layout jumps.\n- **Empty state (`.card--empty`):** structured fallback with a large Material Symbol and short guidance text, defined as part of the system.\n\n**3.3 Forms & Inputs — `.input-group` (Final CTA email capture)**\n- **Structure:** flex container wrapping `\u003Clabel>`, `\u003Cinput>`, and a dedicated error feedback element (`\u003Cp class=\"input-group__error\">` with `aria-live=\"polite\"`).\n- **States (all class-driven):** empty, focused (dashed ink ring), filled, valid (`.is-valid` — success border + `check_circle` icon), invalid (`.is-invalid` — error border, `error` icon, message text), disabled, read-only. Hand-drawn styling: wobbly radius, 2px ink border, paper fill.\n\n**3.4 Modal — `.modal` (newsletter success confirmation; reusable)**\n- **States:** opening, open, loading, success\u002Ferror, closing — all animated with CSS transitions (fade + gentle scale).\n- **UX:** centered flex overlay (`align-items: center; justify-content: center`), backdrop dim, Material Symbols `close` button with `aria-label=\"Close dialog\"`, keyboard focus trapping, close via `Esc` and overlay click, `role=\"dialog\"` + `aria-modal=\"true\"` labelled by the modal title, focus returned to the trigger on close, `z-index: var(--z-modal)`.\n\n---\n\n## 4. Page Section Requirements\n\n**4.1 Header (sticky):** logo in `--font-hand`, anchor nav (Features, How It Works, Pricing, FAQ) with smooth scrolling, the theme toggle (2.3), and a Material Symbols `menu` hamburger on mobile — the mobile menu must be fully keyboard operable. Include a \"Skip to content\" link.\n\n**4.2 Hero:** ruled-paper background with margin line; H1 in `--font-hand` with the highlighter swipe animating across a key phrase on load; short subcopy; two CTAs (`.btn--primary` + `.btn--secondary`) with on-theme copy; character mascot as a sticker with pop-in and idle wobble (`aria-hidden`); doodle stars\u002Fhearts\u002Fsparkles around the headline; ambient scanning-light sweep. All decorative elements hidden from assistive technology.\n\n**4.3 Features — 3 cards:** flex row (wrap) → column on mobile. Each card: Material Symbol icon inside a pastel sticker circle, `--font-hand` title with `.highlight`, body copy, corner doodle. Sticker pop-in on scroll (staggered); hover lift\u002Ftilt; focus-within border.\n\n**4.4 How It Works — 3 steps:** numbered notebook entries — oversized hand-drawn numerals (1, 2, 3) in sticker circles, one Material Symbol per step, title + short copy. Connect steps with a dashed \"pen line\" (CSS border\u002Fpseudo-element) on desktop; stack vertically on mobile. Doodle reveal on scroll.\n\n**4.5 Testimonials — 3–4 sticky-note cards:** alternating slight rotations (−1deg \u002F +1deg), washi-tape strip, quote in `--font-hand`, reviewer name + role in `--font-base`, avatar as a pastel circle with initials (no external images). Star ratings via filled Material Symbols `star` \u002F `star_half` plus visible text (e.g., \"5\u002F5\") so ratings are never conveyed by shape\u002Fcolor alone. Staggered pop-in on scroll.\n\n**4.6 Pricing — 3 tiers:** flex row (wrap) → column on mobile. Middle tier `.card--featured`: \"Most Popular\" sticker badge (rotated, pop-in), pink highlight header, `--shadow-md` elevation. Each tier: name in `--font-hand`, price, feature list with `check_circle` (included) and `cancel` (excluded) icons each paired with text, and a CTA (`.btn--primary` on the featured tier, `.btn--secondary` elsewhere).\n\n**4.7 FAQ — accessible accordion:** 5–6 on-theme Q&As. Each item: `\u003Cbutton class=\"faq__question\">` with `aria-expanded` + `aria-controls`, a `role=\"region\"` panel, and a rotating Material Symbols `expand_more` chevron. Fully keyboard operable, visible focus, smooth CSS height animation (e.g., `grid-template-rows: 0fr → 1fr` technique).\n\n**4.8 Final CTA:** full-width banner on ruled paper; big `--font-hand` headline with highlighter swipe; short copy; email capture `.input-group` + `.btn--primary` submit. Behavior: client-side email validation → loading state → success (inline success message + the confirmation modal from 3.4) or error (`.is-invalid` + `aria-live` error message). Every submission attempt produces visible feedback.\n\n**4.9 Footer:** secondary links grouped into columns (flex, wrap → column on mobile) — e.g., Product, Company, Support — plus a small social icon row (Material Symbols with accessible names), copyright line in `--text-secondary`, a mini mascot doodle, and a smooth-scroll \"back to top\" link.\n\n---\n\n## 5. Core UX & Micro-Interaction Rules\n\n- **Responsive by default:** fluid sizing, standard breakpoints (≈640\u002F768\u002F1024px), zero horizontal overflow, all touch targets ≥44×44px.\n- **Smooth animations:** `transition: var(--transition-normal)` on every state change; `prefers-reduced-motion: reduce` disables the wobble, pop-in, swipe, scanning-light, and accordion animations (replace with simple opacity changes) — motion is decoration, never information.\n- **Accessibility:** WCAG AA contrast in both light and dark themes (use `--primary-ink` for blue text on light backgrounds; keep dark ink over marker highlights via `--ink-on-fill`); never rely on color alone — pair every state with an icon and\u002For text; semantic HTML5 (`header`, `nav`, `main`, `section`, `footer`), exactly one `\u003Ch1>`, logical heading order; correct ARIA roles\u002Flabels on the toggle, accordion, modal, and mobile menu; logical DOM\u002Ffocus order; full keyboard operability — no mouse-only interactions; `aria-live` regions for form feedback and dynamic states; visible focus everywhere.\n- **Mandatory visual feedback:** every click, hover, and submission triggers a visible state change.\n- **Destructive actions:** `.btn--danger` must be visually distinct in both light and dark themes (define it in the component library even if the page contains no delete action).\n\n---\n\n## 6. Deliverables & Output Format\n\n- **Files:** `index.html`, `style.css`, `script.js` — separate, complete files. The HTML references exactly one script: `\u003Cscript src=\"script.js\" defer>\u003C\u002Fscript>` (plus the optional one-line theme bootstrap from 2.3, the sole permitted inline script).\n- **JavaScript scope (script.js only):** theme toggle with `localStorage` persistence; IntersectionObserver for doodle reveal + sticker pop-in; FAQ accordion; mobile menu; smooth anchor scrolling; email form validation with loading\u002Fsuccess\u002Ferror states; modal open\u002Fclose with focus trap, `Esc`, and overlay-click close. JavaScript must never inject inline styles — all state changes flip classes.\n- **Naming:** BEM everywhere, one consistent convention, no mixing.\n- **Copy:** original English copy in the studygram\u002Fjournaling voice (e.g., \"Turn your notes into something cute\"). No lorem ipsum; no unrequested placeholder content.\n- **Assets:** no external images or local icon files — all visuals come from CSS, Google Fonts, Material Symbols, and the permitted decorative inline SVGs (1.5).\n- **CSS organization:** comment-separated sections matching the `@layer` order; tokens at the top.\n- **Final QA pass before output:** keyboard-only walkthrough, both color themes, 320px-wide viewport, reduced-motion mode, and zero `style=\"...\"` attributes in the HTML.\n- **Delivery:** output the complete, working code for all three files in a single response — no partial builds.\n",1791954989542]
