Build a complete, production-ready landing page for a Brazilian indigenous culture platform (preservation, storytelling, community voices) in a **single response on the first attempt** — full HTML, CSS, and JS, no partial output, no follow-up questions. Every decision not specified below is yours to make in keeping with the theme.\n\n---\n\n## 0. PROJECT BRIEF & THEME SPECIFICATION\n\n**0.1 Theme Identity**\n- **Name:** Authentic Indigenous Tropicalism (\"Tropicalismo Indígena Autêntico\")\n- **Type:** Authentic, Cultural, Organic, Respectful\n- **Era:** 2026+ Ancestral Connection\n- **Keywords:** indigenous culture, Brazilian, preservation, authentic, cultural, organic, traditional, storytelling, immersive, respectful\n- **Mood:** Earthy, warm, reverent, immersive — like reading a manuscript under a forest canopy.\n\n**0.2 Color System & Token Mapping** (prescribed starting values; you may only adjust a value if it *improves* WCAG contrast)\n\n| Token | Light Mode | Dark Mode | Role |\n|---|---|---|---|\n| `--primary` | `#8B4513` Earth Brown | `#D9A05F` | Brand, primary buttons, headings |\n| `--secondary` | `#228B22` Forest Green | `#7CC580` | Success, growth accents |\n| `--accent-ochre` | `#CC7722` Ochre Red | `#E09A55` | Signature 2px borders, pattern strokes |\n| `--accent-river` | `#4682B4` River Blue | `#8FC1E3` | Links, focus rings |\n| `--accent-sun` | `#FFD700` Sun Yellow | `#FFD700` | Featured badge, highlights (never body text) |\n| `--accent-ember` | `#CC5500` Burnt Orange | `#FF9D5C` | Danger\u002Ferror borders |\n| `--bg-primary` | `#FEFEFE` | `#16120B` deep earth | Page background |\n| `--bg-secondary` | `#F6EEE0` warm parchment | `#241C11` dark clay | Cards, alternating sections |\n| `--text-primary` | `#8B4513` | `#F2E6D0` parchment | Headings and body |\n| `--text-secondary` | `#6B5B45` | `#C9B493` | Supporting copy |\n| `--text-success` | `#1C731C` | `#8FD694` | Success text |\n| `--text-error` | `#B34700` | `#FFA26B` | Error text |\n| `--border-default` | `#CC7722` | `#CC7722` | Spec-mandated component borders |\n| `--border-subtle` | `#E3D3B8` | `#3A2E1C` | Quiet dividers |\n| `--border-success` \u002F `--border-error` | `#228B22` \u002F `#CC5500` | `#7CC580` \u002F `#FF9D5C` | State borders |\n| `--pattern-stroke` | `rgba(139,69,19,0.18)` | `rgba(242,230,208,0.14)` | Indigenous pattern linework |\n\n**Structural tokens:** `--radius-sm: 4px; --radius-md: 8px; --radius-lg: 20px;` · `--shadow-sm \u002F --shadow-md` (warm-tinted, e.g., `rgba(59,36,10,0.12)` light \u002F near-black dark) · `--spacing-gap: 1.5rem` · `--transition-fast: 0.25s ease-in-out` (control micro-feedback) · `--transition-normal: all 0.7s ease-in-out` (the spec-mandated signature: reveals, section\u002Ftheme transitions, accordions, modals) · `--ease-standard: ease-in-out` · `--z-dropdown: 10; --z-modal: 100; --z-toast: 1000` · `--font-display: 'Marcellus SC', serif; --font-base: 'Lora', serif;` (optional `--font-accent: 'IM Fell English', serif` for pull quotes).\n\n**0.3 Signature Visual Language**\n- **Indigenous patterns in UI:** `.indigenous-pattern-bg` — CSS-generated geometric motifs (zigzags, diamonds, river lines, step frets) built from `repeating-linear-gradient` \u002F `conic-gradient` in `--pattern-stroke`, used on hero, CTA band, step badges, and dividers.\n- **Manuscript typography:** Marcellus SC display face with generous letter-spacing on headings; Lora body; optional calligraphic accent for quotes.\n- **Native fauna & flora:** `.native-illustration` — decorative clusters composed **exclusively** from Google Material Symbols glyphs (`forest`, `eco`, `spa`, `grass`, `potted_plant`, `emoji_nature`, `pets`, `water_drop`, `landscape`, `filter_vintage`, or similar) plus CSS-drawn motifs. **Exception:** none permitted — the requested \"illustrations\" must be Material Symbols + CSS art only; inline SVGs, local image files, and raster images are prohibited.\n- **Clay & wood textures:** `.texture-clay` \u002F `.texture-wood` — layered low-opacity CSS gradients simulating grain; no image files.\n- **Cultural reveal hover:** `.cultural-reveal-hover` — see rule 2.6.\n- **Intertwining section transitions:** `.section-divider` — woven, interlocking triangle strips (CSS gradients, `aria-hidden=\"true\"`) between sections; scroll-reveal entrances at `--transition-normal`.\n\n**0.4 Cultural Respect Constraints (non-negotiable)**\n- Use **original, generic geometric motifs** inspired broadly by Amazonian graphic traditions — never reproduce specific sacred, ceremonial, or community-specific designs or symbols.\n- Copy must be respectful and non-appropriative: emphasize living cultures, community authorship, preservation, and education. No stereotypes, no exoticization.\n- Do not fabricate quotes attributed to real people or real named communities. Testimonial personas use role-based attributions (e.g., \"Educator, Rio de Janeiro\").\n- Include a footer respect line, e.g., \"Created with respect for the living cultures of Brazil.\"\n\n**0.5 Copy & Language**\n- Write **all user-facing copy in English**. Indigenous-language words may appear only as proper nouns (e.g., a platform name) with English context provided.\n- Write real, theme-appropriate copy for every section — **lorem ipsum is prohibited everywhere**. Direction: Hero H1 such as \"Stories the Forest Still Tells\"; primary CTA \"Begin the Journey\"; secondary \"Explore Stories\"; Final CTA \"Join the Circle.\"\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** in the HTML.\n- All design properties, layout rules, and states are targeted via class or ID selectors only.\n- HTML stays clean, semantic, and style-agnostic — retheming must require editing CSS only, never markup.\n\n**1.2 CSS Variables & Theme Tokens**\n- All tokens from 0.2 are defined in `:root` (light) and overridden in `.dark` \u002F `@media (prefers-color-scheme: dark)`.\n- **Contrast pairing:** every light background token pairs with dark text tokens and every dark background token pairs with light text tokens — in both themes. Verify WCAG AA (4.5:1 body text, 3:1 large text\u002FUI). When Forest Green is a *fill* behind light text, use the darkened `#1C731C` variant (white on `#228B22` fails AA at body size).\n- **Near-white rule:** the light page background must never be pure white.\n- **Exception (source spec conflict):** the source spec lists `background: #FFFFFF`; the near-white rule overrides it — use `#FEFEFE` for `--bg-primary`. Pure `#FFFFFF` is permitted only for text\u002Fglyphs on dark fills, never as a page or section background.\n- Spec-mandated base styles: `color: #8B4513` on light backgrounds, `border: 2px solid #CC7722` on signature components (buttons, cards, inputs), `border-radius: 8px` (`--radius-md`).\n\n**1.3 Mandatory Dark Mode Support**\n- Define full dark tokens under both `@media (prefers-color-scheme: dark)` and a `.dark` class on `\u003Chtml>`; include `color-scheme` meta\u002Fproperty so native controls match.\n- Switching must swap variables seamlessly with zero HTML restructuring; animate the swap with `--transition-normal`.\n- Persist choice in `localStorage` (key `theme`), fall back to `prefers-color-scheme` on first visit, and expose a visible toggle in the header with correct `aria-pressed` and `aria-label` (\"Toggle dark mode\") and `light_mode`\u002F`dark_mode` Material Symbols.\n\n**1.4 Flexbox Layout & Mobile-First Alignment**\n- Build all layout structure with Flexbox. Every flex container defaults to `align-items: center` unless an exception is justified in a CSS comment (sanctioned exceptions: `stretch` for equal-height card grids, `flex-start` for stacked label\u002Finput groups).\n- Mobile-first: multi-column rows collapse to columns on small viewports; nothing may cause horizontal scrolling at any width ≥ 320px.\n\n**1.5 Styling Approach & Naming Convention**\n- Use hand-written custom CSS in `style.css` — the source specification supplies raw custom CSS and custom class names, which constitutes the requested approach. Do not add Tailwind or any other framework.\n- **Naming convention: BEM** (`block__element--modifier`) throughout — never mix conventions.\n- **Exception (source spec classes):** `.indigenous-pattern-bg`, `.native-illustration`, and `.cultural-reveal-hover` are retained verbatim as global theme classes; every other class follows BEM.\n\n**1.6 Typography & Icons (Google Fonts Mandatory)**\n- Load **Marcellus SC** (display) and **Lora** (body) — plus the optional accent font if used — via Google Fonts `\u003Clink>` tags with `preconnect`; bind them to `--font-display` \u002F `--font-base`.\n- Icons: Google Material Symbols (Rounded) via the standard stylesheet. Raw inline SVGs and local icon files are **prohibited**.\n\n---\n\n## 2. COMPONENT DESIGN SPECIFICATIONS\n\n**2.1 Button Component (`.btn` + modifiers)**\n- **Default:** `display: flex; align-items: center; justify-content: center; gap: 0.5rem;` minimum touch target 44×44px. Variants: `.btn--primary` (Earth Brown fill, parchment text), `.btn--secondary` (transparent, 2px `--border-default`, `--primary` text), `.btn--ghost`, `.btn--danger` (visually distinct via `--accent-ember` in **both** themes).\n- **Hover:** brightness shift + `--shadow-md`, `cursor: pointer`.\n- **Focus:** distinct ring using `--accent-river` (`outline` + `box-shadow` offset) for keyboard navigation.\n- **Active\u002FPressed:** `transform: scale(0.97)`.\n- **Loading (`.btn--loading`, `aria-busy=\"true\"`):** blocks interaction and double-clicks, renders a CSS spinner or rotating Material Symbol `progress` **without changing button dimensions**.\n- **Disabled:** `opacity: 0.5`, greyscale, `cursor: not-allowed`.\n- **Success\u002FError:** temporary feedback states driven by `--text-success` \u002F `--text-error` (icon + label change, never color alone).\n\n**2.2 Card Component (`.card`)**\n- **Default:** flexible flexbox layout, `--bg-secondary` surface, subtle border, `--radius-md`, `--shadow-sm`.\n- **Hover:** `--shadow-md` + `transform: translateY(-2px)` + `--border-default` emphasis.\n- **Focus-within:** border highlights when a child link\u002Fbutton receives focus.\n- **Loading (`.card--skeleton`):** shimmer animation defined in CSS, no layout jump; required for any dynamically loaded content.\n- **Empty (`.card--empty`):** fallback layout with a Material Symbol and clear guidance text.\n\n**2.3 Form & Input (`.input-group`)**\n- **Structure:** flex container wrapping a `\u003Clabel>`, the input, and a dedicated error feedback container.\n- **States:** empty, focused (river-blue ring), filled, valid (`--border-success` + `check_circle` icon), invalid (`--border-error`, `--text-error` message, `error` icon, `aria-invalid`), disabled, read-only.\n- Errors and status changes are announced via an `aria-live=\"polite\"` region; link messages with `aria-describedby`.\n\n**2.4 Modal \u002F Dialog (`.modal`) — conditional**\n- No modal is required by the brief; if you add one (e.g., a cultural glossary dialog), it must have: animated opening\u002Fopen\u002Fclosing states via CSS transitions, internal loading and success\u002Ferror states, a centered flex overlay (`align-items: center`) with backdrop, a Material Symbol `close` button, `role=\"dialog\"` + `aria-modal`, keyboard focus trapping, and closing via `Esc` or overlay click.\n\n**2.5 FAQ Accordion (`.accordion`)**\n- Each item: a full-width `\u003Cbutton>` trigger (`aria-expanded`, `aria-controls`) with a rotating `expand_more` icon, and a panel (`role=\"region\"`, `aria-labelledby`) animated via CSS transitions.\n- Fully keyboard operable (native buttons); animation respects `prefers-reduced-motion`.\n\n**2.6 Cultural Reveal Interaction (`.cultural-reveal-hover`) — signature micro-interaction**\n- Each pattern, icon, or illustration carrying cultural meaning contains a `.cultural-reveal-hover__meaning` caption (real DOM text, screen-reader accessible) that is visually hidden and reveals on **both** `:hover` and `:focus-within`\u002F`:focus-visible` via opacity\u002Ftransform transition at `--transition-normal` (0.7s).\n- Never hover-only: keyboard focus must trigger the identical reveal. Example: \"This river-line motif evokes the threads that connect communities along the waterways.\"\n- With `prefers-reduced-motion`, the meaning appears instantly without animation.\n\n**2.7 Toast & Live Feedback (`.toast`)**\n- Fixed-position toast at `--z-toast`, `role=\"status\"` \u002F `aria-live=\"polite\"`, success and error variants (icon + text), auto-dismiss, CSS-animated entrance\u002Fexit. Used for form submission, button success, and any dynamic feedback.\n\n---\n\n## 3. CORE UX & MICRO-INTERACTION RULES\n\n- **Responsive by default:** fluid sizing, breakpoints without horizontal overflow (verify at 320px).\n- **Smooth animations:** CSS transitions on all state changes using the token system; the 0.7s `--transition-normal` is the theme's signature for reveals and section\u002Ftheme transitions, `--transition-fast` for control feedback. Fully respect `prefers-reduced-motion` (no transforms, no shimmer, instant reveals).\n- **Accessibility (a11y):** AA contrast in both themes; never communicate state by color alone (always icon + text); semantic HTML5 landmarks (`header`, `nav`, `main`, `section`, `footer`); one `h1`, logical heading hierarchy; correct ARIA roles\u002Flabels on custom widgets; logical DOM\u002Ffocus order; full keyboard operability; skip-to-content link; `aria-live` regions for form errors, toasts, and loading states.\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 design system even if unused).\n\n---\n\n## 4. PAGE SECTION SPECIFICATIONS\n\n**4.1 Global Header & Navigation** — Sticky `\u003Cheader>` at `--z-dropdown`, flex row (centered) with: brand (Material Symbol + Marcellus SC wordmark), `\u003Cnav aria-label=\"Main\">` with anchor links (Features, How It Works, Testimonials, Pricing, FAQ), theme toggle (rule 1.3), and a `menu` hamburger on mobile toggling an animated, keyboard-accessible nav panel (`aria-expanded`, `aria-controls`). Bottom edge finished with a thin pattern strip.\n\n**4.2 Hero** — Full-impact `\u003Csection>` (`min-height: 85vh`, flex column, centered) over `.indigenous-pattern-bg` with `.texture-clay`; `h1` in Marcellus SC; supporting paragraph; CTA row (`.btn--primary` + `.btn--secondary`, all states per 2.1); a `.native-illustration` decorative cluster (`aria-hidden`) of fauna\u002Fflora Material Symbols; at least one `.cultural-reveal-hover` on a pattern motif; scroll cue. Entrance revealed on load.\n\n**4.3 Features — 3 cards** — `h2` + intro, then three `.card`s (grid → single column mobile): **Ancestral Story Library** (`auto_stories`), **Living Voices** (`record_voice_over` or `groups`), **Learn & Preserve** (`school` or `eco`). Each card: icon, title, copy, a cultural-reveal detail, and a focusable \"Explore\" link (demonstrating focus-within). Skeleton and empty-state classes defined per 2.2.\n\n**4.4 How It Works — 3 steps** — Three steps — **01 Listen** (`headphones`), **02 Learn** (`menu_book`), **03 Support** (`volunteer_activism`) — connected by a CSS-drawn intertwining woven connector (interlocking gradient strip) that runs horizontally on desktop and vertically on mobile; numbered badges backed with `.indigenous-pattern-bg`.\n\n**4.5 Testimonials** — Three quote `.card`s with `format_quote` symbol, italic quote (accent font if used), initials avatar in a patterned circle, and role-based attribution per rule 0.4. All card states per 2.2.\n\n**4.6 Pricing — 3 tiers** — **Seed** (free), **River** (monthly, featured), **Forest** (annual guardian). Featured tier: Sun Yellow ribbon badge, 2px `--border-default`, elevated shadow\u002Fscale. Each tier: name, price, feature list with `check_circle` icons, and a CTA button implementing the full 2.1 state machine (click → loading → success toast). Include a note that subscriptions directly support community storytellers.\n\n**4.7 FAQ** — 5–6 accessible accordion items per 2.5 covering: what the platform is, who authors content, how communities are supported, language access, how authenticity\u002Frespect is ensured, and partnerships.\n\n**4.8 Final CTA** — Full-width band with `.indigenous-pattern-bg` + `.texture-wood`, `h2` (\"Join the Circle\"), supporting copy, and an email capture form per 2.3 (label, input with all states, submit button with loading → success, `aria-live` status region, success toast, inline success state). Secondary text link: \"Explore stories first.\"\n\n**4.9 Footer** — Brand + respect line (rule 0.4); secondary link groups (Platform: About, Stories, Education · Support: Contact, Partnerships, FAQ · Legal: Privacy, Terms); social icons (Material Symbols with `aria-label`s); dynamic-year copyright. All links show visible focus rings.\n\n**Section transitions:** place `.section-divider` woven strips between all sections and apply scroll-reveal (`.reveal` → `.is-visible` via IntersectionObserver, opacity + `translateY`, `--transition-normal`) to section content.\n\n---\n\n## 5. DELIVERABLE & OUTPUT FORMAT\n\n- **Files:** separate `index.html`, `style.css`, `script.js`. No inline styles anywhere; no inline `\u003Cscript>` blocks beyond a single deferred entry point (`\u003Cscript src=\"script.js\" defer>`). No inline event handlers — all listeners via `addEventListener`.\n- **script.js must include:** theme toggle with `localStorage` persistence and `prefers-color-scheme` fallback; mobile nav; accordion logic; form validation with simulated async submit; toast system; button loading simulations; IntersectionObserver reveals; focus-trap utility only if a modal exists.\n- **Naming:** BEM everywhere (with the single documented exception for the three spec-mandated theme classes).\n- **Copy:** complete, respectful English copy for every section — no lorem ipsum, no unrequested placeholders.\n- **Output:** the complete, runnable page in one response — all three files, fully implemented, satisfying every rule above. Before finalizing, self-verify: zero inline CSS, both themes pass AA contrast, full keyboard pass, no horizontal scroll at 320px, `prefers-reduced-motion` respected, and every interactive element has visible default\u002Fhover\u002Ffocus\u002Factive\u002Floading\u002Fsuccess-or-error states.\n",1791954984530]
