Build the complete landing page described below in a single attempt, on the first pass. Every rule in this document is mandatory. Where a rule conflicts with a default habit or shortcut, the rule wins.\n\n---\n\n## 0. THEME DIRECTION & DESIGN TOKENS\n\n**0.1 Aesthetic — \"1990s Digital Pixel Nursery\":**\nThe page must feel like a lovingly maintained 1990s garden-software UI. Achieve the retro look exclusively through CSS: **chunky 2–4px solid borders**, **hard-edged offset box-shadows with zero blur** (e.g., `4px 4px 0 var(--border-default)`), **tiny border radii**, **pixel display fonts**, **butter-yellow highlights**, and optional dithered backgrounds via `repeating-linear-gradient`. Never use raster images, external image files, or inline SVGs.\n\n**0.2 Color Mapping (Light = default theme):**\n\n```css\n:root {\n  \u002F* Palette: #2a1f30, #e8d8f0, #3a2a40, #1c1420, #ffe08a, #4a3a50 *\u002F\n  --primary: #2a1f30;        \u002F* deep plum: headings, borders, primary surfaces *\u002F\n  --secondary: #3a2a40;       \u002F* muted plum: hover borders, secondary surfaces *\u002F\n  --plum-muted: #4a3a50;     \u002F* tertiary plum: muted text, dark-mode borders *\u002F\n  --plum-deep: #1c1420;       \u002F* darkest plum: footer band, dark-mode background *\u002F\n  --accent: #ffe08a;          \u002F* butter yellow: CTAs, badges, highlights *\u002F\n  --bg-primary: #e8d8f0;     \u002F* soft lilac page background — NEVER #ffffff *\u002F\n  --bg-secondary: #fefefe;    \u002F* card\u002Fpanel surfaces *\u002F\n  --text-primary: #2a1f30;    \u002F* dark text on light surfaces *\u002F\n  --text-secondary: #4a3a50;\n  --text-on-accent: #2a1f30;  \u002F* dark text always on yellow *\u002F\n  --text-success: #2f6b3a;    \u002F* verify ≥4.5:1 on --bg-secondary *\u002F\n  --text-error: #b03a3a;     \u002F* verify ≥4.5:1 on --bg-secondary *\u002F\n  --border-default: #2a1f30;\n  --border-success: #2f6b3a;\n  --border-error: #b03a3a;\n  --radius-sm: 0px;  --radius-md: 2px;  --radius-lg: 4px;   \u002F* intentionally small: pixel look *\u002F\n  --shadow-sm: 3px 3px 0 0 var(--border-default);          \u002F* hard-edged, zero blur *\u002F\n  --shadow-md: 6px 6px 0 0 var(--border-default);\n  --spacing-gap: 1.5rem;\n  --transition-fast: 120ms; --transition-normal: 240ms;\n  --ease-standard: cubic-bezier(0.2, 0, 0, 1);\n  --ease-pixel: steps(4, end);   \u002F* optional retro easing for blink\u002Fskeleton effects *\u002F\n  --z-dropdown: 100; --z-modal: 1000; --z-toast: 1100; --z-overlay: 900;\n  --font-display: \"Press Start 2P\", \"VT323\", monospace;\n  --font-base: \"VT323\", monospace;\n}\n```\n\n**0.3 Contrast Pairing (enforced in both themes):** Every light background token pairs with `--text-primary` (dark); every dark background token pairs with light text. The `--accent` yellow always pairs with `--text-on-accent`. Verify all text\u002Fbackground pairs meet WCAG AA (≥4.5:1) in both Light and Dark modes.\n\n**0.4 Typography (Google Fonts mandatory):** Load **\"Press Start 2P\"** (display: h1\u002Fh2\u002Fh3, buttons, badges, prices, numbers) with `preconnect` + stylesheet link tags; keep its sizes modest (0.75–2rem) with generous `line-height` (1.4+) and slight `letter-spacing`. Load **\"VT323\"** for body\u002FUI copy at a minimum of `1.125rem` with `line-height: 1.6`. Bind both to `--font-display` \u002F `--font-base`.\n\n**0.5 Icons (Google Material Symbols only):** Use Material Symbols (Rounded) via the Google Fonts stylesheet, e.g., `\u003Cspan class=\"material-symbols-rounded\" aria-hidden=\"true\">potted_plant\u003C\u002Fspan>`. **Inline SVGs, emoji icons, and local icon files are forbidden.** Decorative icons get `aria-hidden=\"true\"`; meaningful icons get accessible text.\n\n**0.6 CSS-Only Pixel Decoration:** You may build an optional decorative pixel-art plant sprite in the Hero using a single element with stacked `box-shadow` values (1px \"pixels\"), marked `aria-hidden=\"true\"` and `pointer-events: none`. If any raster image is ever unavoidable, apply `image-rendering: pixelated` — but prefer none at all.\n\n---\n\n## 1. STRICT ARCHITECTURE RULES (MANDATORY)\n\n**1.1 CSS-First & Zero Inline CSS**\n- All styling lives in `style.css`. The `style=\"...\"` attribute is **forbidden** anywhere in the HTML.\n- Target everything via class\u002FID selectors. HTML stays clean, semantic, and style-agnostic — a full retheme must be possible by editing only `style.css`.\n\n**1.2 CSS Variables & Theme Tokens**\n- Define the full token set from Section 0.2 inside `@layer tokens`. No hard-coded hex values may appear in component rules — every color, radius, shadow, spacing, duration, and z-index must come from `var(--...)`.\n- Redefine all color\u002Fshadow tokens for Dark Mode (see 1.3). Do **not** redefine fonts or radii.\n\n**1.3 Mandatory Dark Mode (explicit exception clause):** *The source spec requests Light as the default theme; Light remains the first-visit default when the OS signals no preference — however a complete, fully-styled Dark Mode is still mandatory and non-negotiable.*\n- Implement dual-mechanism theming in CSS: a `.dark` class on `\u003Chtml>` redefines all tokens, and `@media (prefers-color-scheme: dark) { :root:not(.light) { ...same tokens... } }` handles OS preference with zero flash.\n- Dark token set: `--bg-primary: #1c1420`, `--bg-secondary: #2a1f30`, `--text-primary: #e8d8f0`, `--text-secondary: #b9a8c8`, `--border-default: #4a3a50`, `--text-success`\u002F`--border-success: #86c98a`, `--text-error`\u002F`--border-error: #f28b8b`, `--accent: #ffe08a` (unchanged), shadows `3px 3px 0 0 #0e0a13` \u002F `6px 6px 0 0 #0e0a13`. Set `color-scheme: dark` accordingly.\n- **Persistence:** `script.js` reads `localStorage` key `sprout-theme` at the top of the file (before DOM queries). `\"dark\"` → add `.dark`; `\"light\"` → add `.light`; absent → rely on the media query. Toggle clicks write the choice back to `localStorage`.\n- **Visible toggle control:** a fixed, always-visible 44×44px button (top-right, `z-index: var(--z-overlay)`) swapping Material icons `dark_mode`\u002F`light_mode`, with `aria-pressed=\"true\"` when dark and a dynamically updated `aria-label` (\"Switch to dark theme\" \u002F \"Switch to light theme\"). Pixel-styled with the standard border + hard shadow.\n\n**1.4 Flexbox Layout & Mobile-First**\n- Build every layout with `display: flex`. **Every flex container defaults to `align-items: center`** unless a documented exception exists (e.g., footer columns stretch: `align-items: flex-start`).\n- Mobile-first: single-column stacks that expand to rows at `min-width: 768px` (and optionally `1024px`). Use `flex-wrap` and fluid `clamp()` sizing. **No horizontal scrolling at any viewport width down to 320px** (`box-sizing: border-box` globally, `max-width: 100%`).\n\n**1.5 CSS Approach (explicit framework clause):** *The source spec requests raw CSS techniques (Flexbox, Transitions, Transforms, Box Shadows, Border Radius), so author clean custom CSS — do not pull in a utility-class framework.* Organize `style.css` as `@layer tokens, base, layout, components, utilities`. Do not mix conventions.\n\n**1.6 Google Fonts & Icons Mandatory:** `\u003Clink rel=\"preconnect\">` + Google Fonts stylesheet (Press Start 2P, VT323) and Material Symbols stylesheet in `\u003Chead>`. All user-facing copy in **English**.\n\n---\n\n## 2. COMPONENT DESIGN SPECIFICATIONS\n\n**2.1 Buttons — full state suite (used for all CTAs):**\n- **Default:** `.btn` = `display: flex; align-items: center; justify-content: center; gap: 0.5rem;` min touch target 44×44px, `border: 3px solid var(--border-default)`, `border-radius: var(--radius-sm)`, `box-shadow: var(--shadow-sm)`, font `--font-display`, uppercase, `cursor: pointer`, `transition: transform var(--transition-fast) var(--ease-standard), box-shadow ..., background-color ..., color ...`.\n- **Variants (BEM):** `.btn--primary` (background `var(--accent)`, color `var(--text-on-accent)` — identical in both themes), `.btn--ghost` (transparent background, `var(--text-primary)` text, border visible in both themes).\n- **Hover:** `transform: translate(-2px, -2px)` and shadow grows (e.g., `5px 5px 0 0`) — the pixel \"lift\". Visible on every button.\n- **Focus-visible:** distinct 3px `outline` in `var(--accent)` with `outline-offset: 3px` (readable in both themes); never remove focus styles.\n- **Active\u002FPressed:** `transform: translate(2px, 2px) scale(0.98)` with shadow collapsing to `0 0 0 0` — the retro \"key press\".\n- **Loading (`is-loading`):** disable pointer events, set `aria-busy=\"true\"`, render a CSS-only pixel spinner (a rotating 3px-bordered square) or animated Google icon — **button dimensions must not change**.\n- **Disabled:** `opacity: 0.5`, `filter: grayscale(1)`, `cursor: not-allowed`, no transforms or shadows.\n- **Success\u002FError feedback (`is-success` \u002F `is-error`):** temporary styles driven by `--text-success` \u002F `--text-error` tokens, announced via an `aria-live=\"polite\"` region if triggered dynamically.\n\n**2.2 Cards (Features, Testimonials, Pricing all extend `.card`):**\n- **Default:** `background: var(--bg-secondary)`, `border: 3px solid var(--border-default)`, `border-radius: var(--radius-md)`, `box-shadow: var(--shadow-sm)`, internal flex layout with `align-items: center` where appropriate.\n- **Hover:** `transform: translateY(-2px)` plus shadow growth to `--shadow-md` (with a border-color shift toward `var(--secondary)`).\n- **Focus-within:** card border turns `var(--accent)` when any child link\u002Fbutton receives focus.\n- **Skeleton (`card--skeleton`):** CSS shimmer animation (stepped gradient + `--ease-pixel`) preserving exact card dimensions; disabled under `prefers-reduced-motion`.\n- **Empty state (`card--empty`):** centered Material icon (e.g., `potted_plant`) plus one line of guidance text.\n- **Modifiers:** `card--feature`, `card--pricing`, `card--pricing--featured`, `card--testimonial`.\n\n**2.3 Forms & Inputs (conditional):** No input fields are required by the requested sections — do not add a form unless you include an optional email capture in the Final CTA. **If any input exists**, it must ship the complete state set — Empty, Focused (accent outline ring), Filled, Valid (success border + `check_circle` icon), Invalid (`--border-error` border, error icon, red helper text in a `.input-group__error` container with `aria-live=\"polite\"`), Disabled, Read-only — inside a `.input-group` flex wrapper (label + input + error container).\n\n**2.4 FAQ Accordion (requested interactive widget):**\n- Structure per item: `\u003Cdiv class=\"faq-item\">` containing `\u003Cbutton class=\"faq-item__trigger\" aria-expanded=\"false\" aria-controls=\"faq-panel-N\" id=\"faq-trigger-N\">` (question + rotating `expand_more` Material icon) and `\u003Cdiv class=\"faq-item__panel\" id=\"faq-panel-N\" role=\"region\" aria-labelledby=\"faq-trigger-N\">`.\n- `script.js` toggles `aria-expanded` and an `is-open` class; CSS animates the panel with the `grid-template-rows: 0fr → 1fr` technique (inner wrapper with `overflow: hidden`) using `var(--transition-normal)`.\n- Triggers are native `\u003Cbutton>` elements (Enter\u002FSpace operable), show visible focus rings, and receive the standard hover treatment.\n\n**2.5 Modals — Out of Scope:** No modal is requested; **do not build one**. If a modal ever becomes necessary, it must implement: animated open\u002Fclose states, centered flex overlay with backdrop, Material icon close button, focus trapping, Esc and overlay-click closing, `--z-modal` stacking.\n\n---\n\n## 3. CORE UX & MICRO-INTERACTION RULES\n\n**3.1 Responsive by Default:** Mobile-first breakpoints (480\u002F768\u002F1024), fluid type via `clamp()`, zero horizontal overflow, flex rows collapsing to columns on small screens.\n\n**3.2 Smooth Animations:** Transition all state changes with `var(--transition-fast)` (micro) or `var(--transition-normal)` (panels, theme switch). Under `prefers-reduced-motion: reduce`: disable transforms, shimmer, and smooth scrolling; keep instant state changes.\n\n**3.3 Accessibility:** Semantic HTML5 landmarks (`\u003Cmain>`, `\u003Csection aria-labelledby>`, `\u003Cfooter>`), a skip-to-content link as the first focusable element, strict h1→h2→h3 hierarchy, full keyboard operability, logical focus order, and AA contrast in **both** themes. **Never communicate state by color alone** (badges carry text, errors carry icons + text). All copy in English.\n\n**3.4 Mandatory Visual Feedback:** Every hover, focus, and click produces a visible change (lift, press, color shift, icon rotation). In-page anchor CTAs smooth-scroll via CSS `scroll-behavior: smooth` (reduced-motion guarded).\n\n**3.5 Destructive Actions:** None are requested; if any dangerous action appears, style it with `.btn--danger` using `--text-error`\u002F`--border-error`, distinct in both themes.\n\n---\n\n## 4. DELIVERABLE & OUTPUT FORMAT\n\n- **Files:** `index.html`, `style.css`, `script.js`. Exactly one script reference: `\u003Cscript src=\"script.js\" defer>\u003C\u002Fscript>` before `\u003C\u002Fbody>` — **no inline scripts, no inline styles**.\n- **Head requirements:** `lang=\"en\"`, viewport meta, `\u003Cmeta name=\"color-scheme\" content=\"light dark\">`, title \"Sprout Street — Pixel Plant Nursery\", meta description, Google Fonts + Material Symbols links, `style.css` link.\n- **Naming:** BEM exclusively, consistently across all files.\n- **JS scope (nothing more):** (1) theme toggle + `localStorage` persistence, (2) FAQ accordion ARIA toggling, (3) current-year insertion in the footer. No other behavioral JS.\n- **Copy:** Write authentic, on-brand English copy — plant names, real feature copy, three named testimonials with roles, three priced tiers, and 5–6 genuine FAQ questions (shipping, plant guarantee, pot sizes, returns). **Lorem ipsum is forbidden.** Footer links use in-page anchors (`#features`, `#pricing`, `#faq`) where targets exist; purely informational links (Privacy, Terms, About) may use `href=\"#\"` with descriptive accessible names — never fake external URLs.\n\n---\n\n## 5. PAGE SECTION BUILD PLAN (exact order)\n\n**5.1 Hero (`#hero`):** Centered flex column, `min-height: 80vh`, lilac background. Pixel-style eyebrow badge (\"EST. 199X — PIXEL NURSERY\"), h1 in `--font-display` with one butter-yellow highlighted word, subhead in `--font-base`, and two CTAs: `.btn--primary` \"Browse the Seedlings\" → `#pricing`, `.btn--ghost` \"How It Works\" → `#how-it-works`. Include the optional CSS box-shadow pixel-plant sprite (`aria-hidden`).\n\n**5.2 Features (`#features`):** Section header (title + subtitle), then 3 `.card--feature` in a responsive flex row (column on mobile). Each card: Material icon (`potted_plant`, `water_drop`, `local_shipping` or similar) inside a bordered pixel badge, h3, two-line copy. Full card hover\u002Ffocus-within states per 2.2.\n\n**5.3 How It Works (`#how-it-works`):** 3 steps in a flex row with numbered badges (\"01\u002F02\u002F03\" in `--font-display`), Material icons, short copy, and a dashed connector line between steps on desktop (pseudo-elements, hidden on mobile).\n\n**5.4 Testimonials (`#testimonials`):** 3 `.card--testimonial`: `format_quote` icon, quoted copy, reviewer name, role, and a CSS-only square avatar (bordered initials — no images).\n\n**5.5 Pricing (`#pricing`):** 3 `.card--pricing` tiers (e.g., Seedling \u002F Sapling \u002F Evergreen) with price in `--font-display`, feature lists with `check_circle` icons, and one `.btn` per tier with a distinguishing `aria-label` (\"Choose the Sapling plan\"). The middle tier is `card--pricing--featured`: visually elevated (scale\u002Ftranslate, `--shadow-md`, accent border) plus a **text badge \"MOST POPULAR\"** (accent background, dark text — never color alone).\n\n**5.6 FAQ (`#faq`):** 6 accordion items exactly per 2.4, introduced by a section header.\n\n**5.7 Final CTA (`#cta`):** Full-width butter-yellow band (`--accent` background, `--text-on-accent` text), bold headline, one supporting line, and one large `.btn--primary`. (Optional: a single email input, only with the full 2.3 state suite.)\n\n**5.8 Footer:** Dark plum band (`--plum-deep` background, `--text-primary` light — this pairing holds in both themes). Flex columns (brand blurb + Shop links + Help links + legal), secondary text links with hover feedback, 3–4 social icon links (`aria-label` each), divider, and \"© \u003Cspan id=\"year\">2024\u003C\u002Fspan> Sprout Street\" with a back-to-top link to `#hero`.\n\n---\n\n## 6. ACCEPTANCE CHECKLIST (verify before submitting)\n\n1. Zero `style=\"...\"` attributes; zero inline scripts; all styles via `var(--...)` tokens.\n2. Light default; Dark Mode complete, toggleable, persisted, `aria-pressed`\u002F`aria-label` correct.\n3.
