Build a complete, production-quality landing page on the first attempt — deliver the full, final code for all files in a single response. No outlines, no stubs, no \"to be continued.\"\n\n**Project Brief:** A landing page for **SCRAPLAB**, a creative reuse and upcycling community platform. Theme: **Disruptive Creative Reuse** (source: \"Reuso Criativo Disruptivo\"). Style: Innovative, Sustainable, Raw, Playful. Keywords: upcycling, creative reuse, sustainable, innovative, raw, playful, unconventional, DIY, community, eco-friendly. Era: 2026+ Circular Economy. Visual direction: inspired by the Campana Brothers — scrap, rope, and recycled-material textures in UI elements; imperfect stencil-effect typography; photographs of upcycled objects focused on transformation; hover micro-interactions where pieces \"assemble\"\u002F\"disassemble\"; section transitions with collage\u002Fcut-out effects; lime green and vibrant orange accents. Output category: **Playful & Youth** — all user-facing copy in **English**, energetic and irreverent but clear.\n\n---\n\n## 1. STRICT RULES & ARCHITECTURE\n\n### 1.1 CSS-First Architecture & Zero Inline CSS\n* **No Inline CSS:** The `style=\"...\"` attribute is forbidden anywhere in the HTML.\n* **Class\u002FID Selectors Only:** All design properties, layout rules, and states are applied via class\u002FID selectors in a dedicated `style.css`.\n* **Minimal HTML Modifications:** HTML stays semantic and styling-agnostic — changing the look must only require editing `style.css`.\n\n### 1.2 CSS Variables & Theme Tokens\nStore all tokens in `:root` (and theme overrides per 1.3):\n\n* **Colors (palette mapping):** `--primary: #32CD32` (Lime Green); `--secondary: #FF8C00` (Vibrant Orange); `--accent-blue: #00BFFF` (Electric Blue); `--accent-purple: #8A2BE2` (Deep Purple); `--accent-yellow: #FFD700` (Sun Yellow); `--accent-red: #CB4154` (Brick Red); `--bg-primary: #fefefe` (the palette's `#FFFFFF` is implemented as `#fefefe` everywhere — never pure white); `--bg-secondary: #F2F1ED` (light concrete tint); `--text-primary: #333333`; `--text-secondary: #5A5A5A`; `--text-success: #1F7A1F`; `--text-error: #B23344`; `--border-default: #A9A9A9` (Concrete Gray); `--border-error: #CB4154`; `--border-success: #1F7A1F`.\n* **Signature scrap token:** `--border-scrap: 2px dashed var(--border-default)` with default `border-radius: 5px` (per source spec).\n* **Contrast Pairing (mandatory, every theme):** Lime `#32CD32`, Orange `#FF8C00`, Yellow `#FFD700`, and Blue `#00BFFF` **fail WCAG AA as text on light backgrounds** — use them only as backgrounds (paired with `#1A1A1A` text), borders, and large decorative elements. Text-safe on light backgrounds: `#333333`, `#5A5A5A`, `#8A2BE2`, `#1F7A1F`, `#B23344`. Concrete Gray `#A9A9A9` is for borders\u002Ftextures only — never body text. In dark mode, the bright accents become text-safe on charcoal.\n* **Radius & Shadows:** `--radius-sm: 5px`, `--radius-md: 10px`, `--radius-lg: 20px`; `--shadow-sm`, `--shadow-md` — prefer hard-edged \"cut paper\" shadows (e.g., `4px 4px 0 rgba(51,51,51,0.15)`) over soft blurs to keep the raw collage feel.\n* **Spacing & Transitions:** `--spacing-gap`; `--transition-fast: 0.2s ease-in-out`; `--transition-normal: 0.5s ease-in-out` (per source spec); `--ease-standard: ease-in-out`; `--ease-snap: cubic-bezier(0.34, 1.56, 0.64, 1)` for assembly \"snap\" effects. **Never write `transition: all`** — always list explicit properties.\n* **Elevation\u002FStacking:** `--z-dropdown`, `--z-modal`, `--z-toast`.\n* **Mandatory classes from source spec:** `.recycled-texture-bg`, `.stencil-text`, `.collage-transition` must exist and behave as defined in Section 3.\n\n### 1.3 Mandatory Dark Mode Support\n* Define dark tokens under **both** `@media (prefers-color-scheme: dark)` and a `.dark` class on `\u003Chtml>`; switching variables must require zero HTML restructuring.\n* Dark palette (\"workshop at night\"): `--bg-primary: #141414`, `--bg-secondary: #1E1E1C`, `--text-primary: #F5F4EF`, `--text-secondary: #B9B9B9`, borders `#6E6E6E`; bright accents (lime, orange, blue, yellow) are text-safe here.\n* **Persistence:** theme choice saved to `localStorage`, falling back to `prefers-color-scheme`; visible toggle control in the header with correct `aria-pressed` and dynamic `aria-label` (\"Switch to dark mode\" \u002F \"Switch to light mode\") and a Google Material Symbol icon.\n* **Exception clause:** The source specification requested a light-mode-first presentation — default to **Light** on first visit; dark mode remains fully implemented and toggleable.\n\n### 1.4 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 CSS comments.\n* Mobile-first: multi-column rows convert to single columns below 768px; **zero horizontal overflow** at any viewport down to 320px.\n\n### 1.5 CSS Approach — Hand-Written Custom CSS (No Framework)\n* The source spec supplies raw CSS values and custom class names, which takes precedence: write plain, hand-written CSS in `style.css`. No Tailwind, no frameworks, no preprocessors.\n* Reusable component classes: `.btn`, `.card`, `.input-group` plus variants. **One naming convention only:** kebab-case descriptive classes (matching `.recycled-texture-bg`, `.stencil-text`, `.collage-transition`). Never mix conventions.\n\n### 1.6 Typography & Icons (Google Fonts Mandatory)\n* **Text:** Google Fonts via `\u003Clink>`: **\"Permanent Marker\"** (display\u002Fheadings, per source spec) and **\"Space Grotesk\"** (body, weights 400\u002F500\u002F700). Bind `--font-display: 'Permanent Marker', cursive` and `--font-base: 'Space Grotesk', sans-serif`.\n* **Stencil accents:** optionally add Google Font **\"Allerta Stencil\"** for tags, labels, and eyebrows.\n* **Icons:** Google Material Symbols (Outlined) only. **Inline SVGs, local icon files, and emoji-as-icons are forbidden.**\n* `.stencil-text`: stencil\u002Fmarker font, uppercase, generous letter-spacing, slight imperfect rotation (−2° to 2° via `nth-child` variations), high-contrast color.\n\n---\n\n## 2. COMPONENT DESIGN SPECIFICATIONS\n\n### 2.1 Button Component Requirements\n* **Default:** `.btn` — `display: flex; align-items: center; justify-content: center; gap: 0.5rem;` minimum touch target 44×44px; `border-radius: var(--radius-sm)`.\n* **Variants:** `.btn-primary` (lime bg, `#1A1A1A` text), `.btn-secondary` (orange bg, `#1A1A1A` text), `.btn-outline` (transparent bg, `--border-scrap` dashed border, `--text-primary` text; hover fills with concrete tint), `.btn-danger` (brick red bg, white text — visually distinct in both themes).\n* **Hover:** brightness\u002Fshadow shift + \"assembly\" micro-interaction — a pseudo-element scrap layer behind the button shifts 2–3px as pieces snap together; `cursor: pointer`; dimensions unchanged.\n* **Focus:** distinct ring — `outline: 3px solid var(--accent-blue); outline-offset: 2px` — visible in both themes.\n* **Active\u002FPressed:** `transform: scale(0.97)`.\n* **Loading (`.is-loading`):** disables interaction and prevents double-clicks, sets `aria-busy=\"true\"`, renders a CSS spinner or spinning Material Symbol without distorting button dimensions.\n* **Disabled:** `opacity: 0.5`, grayscale, `cursor: not-allowed`.\n* **Success\u002FError (`.is-success` \u002F `.is-error`):** temporary feedback driven by `--text-success` \u002F `--text-error`, always with icon + text (never color alone).\n\n### 2.2 Card Component Requirements\n* **Default:** `.card` — flexible flexbox column, `--bg-secondary`, dashed or solid border with hard shadow, `padding: var(--spacing-gap)`.\n* **Hover:** `transform: translateY(-2px)` + shadow shift + assembly effect: decorative pseudo-element \"scrap pieces\" (tape strips, corner patches) shift\u002Frotate 2–4° as if snapping together.\n* **Focus-within:** border color shifts to `--accent-blue` when a child link\u002Fbutton receives focus.\n* **Loading (Skeleton):** define `.card--skeleton` with a CSS shimmer gradient sweep reserving exact dimensions — no layout jumps.\n* **Empty State:** define `.card--empty` with a large Google Material Symbol and clear guidance text.\n\n### 2.3 Form & Input Requirements\n* **Structure:** `.input-group` — flex container wrapping a `\u003Clabel>`, the input, and a dedicated error feedback element (`\u003Cp class=\"field-error\">` inside an `aria-live=\"polite\"` region).\n* **States:** Empty, Focused (outline ring via `--accent-blue`), Filled, Valid (success border + check Material Symbol), Invalid (error border, `--text-error` message + error icon — never color alone), Disabled, Read-only.\n* The Final CTA newsletter form must implement client-side email validation with inline errors and a success confirmation (button enters `.is-success`, status announced via `aria-live`).\n\n### 2.4 Accordion (FAQ) Requirements\n* Each item: `\u003Ch3>\u003Cbutton class=\"faq-trigger\" aria-expanded=\"false\" aria-controls=\"...\">` plus a panel with `role=\"region\"` and `aria-labelledby`.\n* Open\u002Fclose animated via CSS (`grid-template-rows: 0fr → 1fr` or `max-height`) using `var(--transition-normal)`; chevron Material Symbol rotates 180°.\n* Fully keyboard operable with visible focus rings; no mouse-only interactions.\n\n### 2.5 Modal \u002F Popup Requirements (Conditional)\n* This landing page does not require modals. If any overlay is introduced, it must have: opening\u002Fopen\u002Fclosing CSS-animated states, centered flex container (`align-items: center`), backdrop, Material Symbol close button, keyboard focus trap, and close via `Esc` or overlay click, layered with `var(--z-modal)`.\n\n---\n\n## 3. CORE UX & MICRO-INTERACTION RULES\n\n* **Responsive by Default:** fluid `clamp()` typography; breakpoints without horizontal overflow.\n* **Smooth Animations:** explicit-property transitions using tokens on all state changes; **respect `prefers-reduced-motion`** — disable jitter, parallax, assembly shifts, and bounce effects; content stays fully accessible.\n* **Accessibility (a11y):** WCAG AA contrast in both modes (follow the 1.2 pairing table); semantic HTML5 (`header`, `nav`, `main`, `section`, `article`, `figure`, `footer`); exactly one `\u003Ch1>` with logical heading order; correct ARIA roles\u002Flabels on custom widgets; logical DOM\u002Ffocus order; full keyboard operability; `aria-live` regions for form errors, loading, and dynamic feedback; never rely on color alone. Decorative pseudo-elements\u002Fspans must be `aria-hidden=\"true\"`.\n* **Mandatory Visual Feedback:** every click, hover, or submission triggers a visible state change.\n* **Signature Theme Effects:**\n  * **Assembly\u002Fdisassembly hover:** interactive cards and buttons carry 2–3 \"scrap\" pseudo-element pieces that shift apart or snap together on hover — subtle (2–6px translate, 2–4° rotate), never distorting layout.\n  * **Collage\u002Fcut-out transitions (`.collage-transition`):** adjacent sections separated by torn-paper\u002Fcut-out edges via `clip-path` polygons or rotated \"paper strip\" pseudo-elements; alternate section backgrounds (`#fefefe` ↔ concrete tint ↔ one dark charcoal band); decorative semi-transparent tape strips in palette colors, slightly rotated.\n  * **Recycled textures (`.recycled-texture-bg`):** CSS-only — corrugated cardboard (repeating-linear-gradient stripes), rope-twist borders (repeating gradients), pierced\u002Fdotted patterns (radial-gradient). No external texture images.\n  * **Stencil typography (`.stencil-text`):** imperfect, slightly rotated, uppercase; interactive instances get a subtle \"re-stamp\" hover (scale 1.02 + rotation settle).\n* **Images:** use seeded picsum placeholders (e.g., `https:\u002F\u002Fpicsum.photos\u002Fseed\u002Fscraplab-hero\u002F800\u002F600.jpg`) with descriptive alt text about upcycled objects; style photos with torn edges (`clip-path`), slight rotation, and tape accents; a grayscale→color hover filter reinforces the \"transformation\" narrative.\n\n---\n\n## 4. LANDING PAGE SECTION-BY-SECTION SPECIFICATIONS\n\nWrite real, on-theme English copy for every section — lorem ipsum is prohibited. Playful-youthful tone throughout.\n\n### 4.1 Global Header (required infrastructure)\nSticky header: stencil wordmark \"SCRAPLAB,\" anchor nav (Features, How It Works, Testimonials, Pricing, FAQ), theme toggle (per 1.3), and a `.btn-primary` \"Join the Makers.\" On mobile, nav collapses behind a hamburger (Material Symbol) with `aria-expanded`, panel layered at `var(--z-dropdown)`, and no horizontal scroll.\n\n### 4.2 Hero\nEyebrow in `.stencil-text`: \"EST. 2026 · CIRCULAR ECONOMY.\" H1 in Permanent Marker (e.g., \"Trash In. Treasure Out.\"), subcopy explaining the platform (makers, rescued materials, swap meets). Two CTAs: `.btn-primary` \"Start Making\" + `.btn-outline` \"Explore the Gallery.\" Visual: a collage of 2–3 upcycled-object photos at rotations with tape\u002Ftorn edges, including a labeled \"Before → After\" transformation pair (stencil tags: \"BEFORE: SCRAP\" \u002F \"AFTER: UPCYCLED\"). Gentle bounce scroll cue (reduced-motion safe).\n\n### 4.3 Features — 3 Cards\nSection label (`.stencil-text`) + H2. Three `.card` elements, each with a Material Symbol icon in a lime\u002Forange scrap badge, title, 1–2 sentence description, and a \"Learn more →\" text link (focus-within highlights the card): (1) **Material Marketplace** — source rescued scraps and offcuts from local donors; (2) **DIY Workshops & Guides** — step-by-step upcycling builds; (3) **Community Swap Meets** — trade creations and materials locally. Hover triggers the assembly effect.\n\n### 4.4 How It Works — 3 Steps\nOversized stencil numerals **01 \u002F 02 \u002F 03**: \"Rescue\" (source scrap materials), \"Rebuild\" (transform with guides), \"Release\" (share, swap, sell with the community). Steps connected by a dashed \"rope\" line on desktop, stacked vertically on mobile; each has an icon and short description; staggered scroll-reveal.\n\n### 4.5 Testimonials\nThree quote cards styled as taped, torn-paper notes with slight `nth-child` rotations: maker photo (picsum, torn frame), name, role (e.g., \"Pallet Furniture Builder\"), quote, and a 5-star rating via filled Material Symbol \"star\" icons with an explicit screen-reader label.\n\n### 4.6 Pricing — 3 Tiers\n**Scavenger** (Free): browse + 1 swap\u002Fmonth + community access. **Maker** ($12\u002Fmo, \"MOST POPULAR\" stencil tag, elevated with lime border and hard shadow): unlimited swaps, all workshops, marketplace selling. **Studio** ($39\u002Fmo): teams, bulk material sourcing, priority pickup. Each tier lists features with Material Symbol check icons and a CTA button (featured tier uses `.btn-primary`); all button states per 2.1 apply.\n\n### 4.7 FAQ\nFive accordion items (per 2.4) covering: accepted materials, whether DIY experience is needed, how pickup\u002Fshipping works, selling upcycled creations, and environmental impact.\n\n### 4.8 Final CTA\nFull-width dark charcoal band (works in both themes) with `.collage-transition` torn edges, big stencil H2 (e.g., \"Landfill is full of good ideas. Dig in.\"), and an email-capture `.input-group` (per 2.3) + `.btn-primary` \"Get the Scrap Drop\" with full validation, loading, and success states plus `aria-live` feedback. Reassurance line: \"No spam. Just scraps.\"\n\n### 4.9 Footer with Secondary Links\nDark charcoal footer: brand block (stencil logo + one-line mission), four secondary link columns — **Platform** (Features, Pricing, Marketplace, Workshops), **Community** (Swap Meets, Maker Profiles, Guidelines, Blog), **Support** (Contact, FAQ, Material Safety, Accessibility), **Legal** (Privacy, Terms, Cookies) — social icons (Material Symbols with `aria-label`), and copyright: \"© 2026 SCRAPLAB — Built from 100% reused pixels.\" All links have visible `:focus-visible` styles.\n\n---\n\n## 5. DELIVERABLE & OUTPUT FORMAT\n\n* **File Structure:** Separate, complete `index.html`, `style.css`, and `script.js`. Zero inline styles; no inline `\u003Cscript>` blocks beyond a single deferred entry-point reference (`\u003Cscript src=\"script.js\" defer>\u003C\u002Fscript>`).\n* **`script.js` must implement:** theme toggle with `localStorage` persistence and `prefers-color-scheme` fallback (defaulting to Light per the exception in 1.3); mobile nav toggle; FAQ accordion behavior; newsletter validation with all input states and `aria-live` feedback; smooth anchor scrolling (or CSS `scroll-behavior` with a reduced-motion guard and `scroll-padding-top` for the sticky header); IntersectionObserver reveal-on-scroll (`.reveal` → `.is-visible`) disabled under `prefers-reduced-motion`.\n* **Naming Convention:** one consistent kebab-case descriptive convention across the entire deliverable (including `.recycled-texture-bg`, `.stencil-text`, `.collage-transition`, `.btn`, `.card`, `.input-group`) — never mix conventions.\n* **No Unrequested Placeholders:** write real on-theme English copy for every headline, description, testimonial, pricing feature, and FAQ answer; picsum images are permitted only for photographs.\n* **Output:** the complete, final code for all three files in one response, ready to run in a browser.\n",1791954984594]
