[{"data":1,"prerenderedAt":4},["ShallowReactive",2],{"prompt-770-ZOETROPE-chronophotography-machine":3},"**SYSTEM PROMPT — CODING AGENT: LANDING PAGE BUILD**\n**Project: \"ZOETROPE — Chronophotography Machine\"**\n\n**Role:** Act as a Senior Frontend Engineer and Expert UI Designer. Your task is to code a complete Landing Page on the first attempt. Every rule in this document is mandatory unless explicitly marked optional.\n\n---\n\n**0. PROJECT BRIEF & THEME DIRECTION**\n\n**0.1 Concept & Style**\nBuild a **neumorphism (soft-UI) landing page** for ZOETROPE, a fictional 2020s chronophotography machine that captures motion as sequential frame slices and renders them into looping \"chronophotographs\" (Muybridge-style motion sequences). The page must blend vintage-cinema warmth with modern digital soft-UI: extruded\u002Finset surfaces, generous border radii, warm cream-and-brown palette, subtle machine motion, and gold glow accents.\n**Keywords:** zoetrope, chronophotography, neumorphism, animated, gradient. **Era:** 2020s Digital.\n**Mandatory effects & techniques:** Glow, Neumorphism, Gradients, Hover Effects — implemented with Flexbox, Transitions, Transforms, Box Shadows, Border Radius, `aspect-ratio`, and CSS Masks.\n\n**0.2 Required Page Structure (exact order)**\n1. Sticky header\u002Fnavigation (logo, anchor links, theme toggle, primary CTA)\n2. Hero\n3. Features — exactly 3 cards\n4. How It Works — exactly 3 steps\n5. Testimonials\n6. Pricing — exactly 3 tiers\n7. FAQ — accordion\n8. Final CTA — with email capture form\n9. Footer — with secondary link columns\n\n**0.3 Color System & Token Mapping**\nMap the supplied palette as follows. Never use `#ffffff` anywhere; derive near-whites from `#fefefe` (e.g., `rgba(254,254,254,…)`).\n\n*Light theme (default presentation):*\n- `--bg-primary: #e8dcc8` (warm cream page background — never pure white)\n- `--bg-secondary: #efe4d1` (raised surfaces; keep within ±4% lightness of the page background — the neumorphic illusion must come from shadows, not background contrast)\n- `--primary: #1c1410` · `--secondary: #8a795c`\n- `--text-primary: #1c1410` · `--text-secondary:` a darkened derivative of `#8a795c` that passes 4.5:1 on cream (e.g., `#6b5c45`); reserve raw `#8a795c` for icons, borders, decorative accents, and large display text only\n- Accent gold `#e8c98f`: gradients, glows, highlights — never as text color on cream\n\n*Dark theme:*\n- `--bg-primary: #120c08` · `--bg-secondary: #1c1410` · `--text-primary: #e8dcc8` · `--text-secondary: #8a795c` (passes on near-black) · accent `#e8c98f`\n\n*Shared \u002F additional tokens:*\n- `--text-success`, `--text-error`: warm-tinted hues that pass WCAG AA in **both** themes and remain distinct from the gold accent\n- `--border-default` (low-opacity brown, e.g., `rgba(28,20,16,.12)` light \u002F `rgba(232,220,200,.12)` dark), `--border-error`, `--border-success`\n- `--gradient-accent: linear-gradient(135deg, #e8c98f, #8a795c)` (gold→bronze)\n- Neumorphic tokens: `--neu-light` \u002F `--neu-dark` (dual shadow colors; light source from top-left; in dark mode the highlight must be a gold\u002Fcream-tinted low-alpha so relief stays visible), `--shadow-out` (extruded), `--shadow-in` (pressed), `--glow` (e.g., `0 0 24px rgba(232,201,143,.45)`)\n\n**0.4 Signature Visual Elements (must appear)**\n- **Hero zoetrope drum:** a pure-CSS circular machine — `aspect-ratio: 1\u002F1`, `border-radius: 50%`, layered `conic-gradient` frame segments, viewing slits rendered with CSS masks (`mask-image` + `-webkit-mask-image` with `repeating-linear-gradient`), slow continuous rotation via keyframes, an inset neumorphic center hub, and a resting gold glow. No images, no inline SVG.\n- **Chronophotograph strip:** a horizontal row of 8–12 small neumorphic frame tiles in which a gold glow\u002Fopacity pulse travels sequentially (staggered `animation-delay`), evoking a Muybridge motion sequence.\n- **Gradient usage:** `--gradient-accent` on the hero headline (`background-clip: text`), primary buttons, the highlighted pricing tier (badge\u002Fborder), and soft radial glow washes behind the hero and final CTA. Keep neumorphic surfaces flat-toned — gradients are for accents, glows, and backdrops only.\n- `aspect-ratio` and CSS Masks must be demonstrably used (the drum and strip satisfy this).\n\n**0.5 Copy Direction**\nWrite complete, realistic **English** marketing copy for every section: headlines, subcopy, three feature titles\u002Fdescriptions, three step descriptions, three testimonial quotes with invented names\u002Froles, three plan names\u002Fprices\u002Ffeature lists, 4–6 FAQ Q&As, CTA copy, and footer labels. All copy must reference chronophotography, motion capture, frame sequencing, and looping. No lorem ipsum anywhere.\n\n---\n\n**1. STRICT RULES & ARCHITECTURE**\n\n**1.1 CSS-First Architecture & Zero Inline CSS**\n- All styling lives in a dedicated `style.css`. **Forbidden:** `style=\"...\"` attributes in HTML.\n- Class\u002FID selectors only. HTML stays semantic and styling-agnostic — retheming the page must be achievable by editing CSS alone.\n\n**1.2 CSS Variables & Theme Tokens**\n- Define in `:root` (plus theme overrides): `--primary`, `--secondary`, `--bg-primary`, `--bg-secondary`, `--text-primary`, `--text-secondary`, `--text-success`, `--text-error`, `--border-default`, `--border-error`, `--border-success`; `--radius-sm`, `--radius-md` (≥12px), `--radius-lg` (≥24px); `--shadow-sm`, `--shadow-md` plus the neumorphic\u002Fglow tokens from 0.3; `--spacing-gap`, `--transition-fast`, `--transition-normal`, `--ease-standard`; `--z-dropdown`, `--z-modal`, `--z-toast`.\n- **Contrast pairing enforced in every theme:** light backgrounds pair with dark text; dark backgrounds pair with light text.\n\n**1.3 Mandatory Dark Mode Support**\n- **Exception clause:** the source specification marks Light Mode as the primary presentation (✓ Light \u002F ○ Dark); Dark Mode is **not** optional — implement both fully, with Light as the default theme when no preference is detectable.\n- Provide dark tokens under `@media (prefers-color-scheme: dark)` **and** a `.dark` class override; switching themes must require zero HTML restructuring.\n- Persist the user's choice via `localStorage`; on first visit fall back to `prefers-color-scheme`. Include a visible header toggle (Material Symbols `light_mode`\u002F`dark_mode`) with correct `aria-pressed` and an `aria-label` that reflects the current state.\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 explicitly justified (note exceptions in a CSS comment).\n- Mobile-first: hero, feature grid, steps, pricing, and footer columns stack vertically at the small breakpoint. No horizontal scrolling at any viewport width down to 320px.\n\n**1.5 Framework & Utility Integration**\n- Tailwind CSS is permitted for layout\u002Fspacing utilities, or clean custom CSS organized via `@layer`\u002F`@apply` — pick **one** approach and apply it consistently. All color, neumorphic, and state styling must live in reusable component classes (`.btn`, `.card`, `.input-group`, `.accordion`, `.badge`) that resolve to `var(--...)` tokens. Never hardcode hex values inside utilities.\n\n**1.6 Typography & Icons (Google Fonts Mandatory)**\n- Text: Google Fonts only — use **Space Grotesk** (display, 500\u002F700) + **Inter** (body, 400\u002F500\u002F700), or an equivalent Google pairing suited to 2020s digital soft-UI. Bind via `--font-display` and `--font-base`, applied through CSS only. Include preconnect + stylesheet links.\n- Icons: **Google Material Symbols (Rounded)** exclusively. **Forbidden:** inline SVGs, local icon files, emoji as icons.\n\n---\n\n**2. SECTION-BY-SECTION BUILD SPECIFICATION**\n\n**2.1 Header & Navigation**\nSticky neumorphic soft bar (subtle bottom shadow, backdrop blur): logo wordmark \"ZOETROPE\" with an `aperture` icon, anchor links (Features, How It Works, Testimonials, Pricing, FAQ), theme toggle, primary CTA \"Start Capturing\". On mobile, links collapse into a `menu` Material Symbol button that opens an overlay drawer (see 3.4). Apply `scroll-margin-top` to sections so anchors clear the sticky header.\n\n**2.2 Hero**\nTwo-column flex row (stacks on mobile): left — eyebrow chip (\"The chronophotography machine\"), one `h1` with gradient accent text, supporting subcopy, two buttons (primary \"Start Capturing\" and a secondary \"See It in Motion\" that smooth-scrolls to How It Works), plus a compact sequence stat strip (e.g., \"12 frames · 1\u002F1000s slices · endless loops\"). Right — the zoetrope drum (0.4) with the chronophotograph strip beneath it.\n\n**2.3 Features — 3 Cards**\nNeumorphic cards, flex layout, each with an inset circular icon well (Material Symbols: `motion_photos_on`, `grid_view`, `replay` or similar), an `h3` title, and 2–3 sentences of copy (e.g., motion-slice capture, frame-true sequencing, instant loop rendering).\n\n**2.4 How It Works — 3 Steps**\nThree numbered stages (01\u002F02\u002F03): extruded number circles, icon, title, copy (position the subject → calibrate frame slices → spin and loop). Desktop: flex row; mobile: vertical timeline.\n\n**2.5 Testimonials**\n3 neumorphic quote cards: five-star row (Material Symbol `star`, filled via `font-variation-settings: 'FILL' 1`), quote text, author row with a CSS initials-avatar circle (no images), invented name, and role.\n\n**2.6 Pricing — 3 Tiers**\nThemed plan names (suggested: \"Reel\" — Free, \"Drum\" — $19\u002Fmo, \"Studio\" — $49\u002Fmo; refine copy as needed). Middle tier highlighted: \"Most Popular\" badge, gradient border, stronger glow, slight raise. Each card: plan name, price + period, divider, feature list with `check` icons, CTA button (secondary for outer tiers, primary for the highlighted tier). All pricing buttons anchor to the Final CTA section.\n\n**2.7 FAQ**\n4–6 themed Q&As as an accordion: header `\u003Cbutton>` with the question plus `expand_more` chevron that rotates 180°, `aria-expanded` + `aria-controls`, panel height animated via CSS (`grid-template-rows: 0fr → 1fr` or equivalent). State must never be communicated by color alone.\n\n**2.8 Final CTA**\nFull-width soft panel with a radial gold glow wash: `h2`, supporting line, and the email capture form (see 3.3). On submit: button enters loading state, a simulated async outcome renders success (icon + message in `--text-success`) or inline error (icon + message in `--text-error`, error border) near the field, announced via `aria-live`. No page reload; double submissions blocked.\n\n**2.9 Footer**\nSecondary links in flex columns (Product \u002F Resources \u002F Company \u002F Legal — real-sounding labels such as \"Frame Gallery\", \"Capturing Guide\", \"Press Kit\", \"Terms of Service\"), Material Symbol social icons (`photo_camera`, `mail`, `rss_feed` — no brand SVGs), logo, tagline, and copyright with current year. Links may target page anchors; use `\"#\"` only where no real target exists, each with a descriptive accessible name.\n\n---\n\n**3. COMPONENT STATE SPECIFICATIONS**\n\n**3.1 Buttons**\n- **Default:** `display: flex; align-items: center; justify-content: center; gap: 0.5rem;` minimum 44×44px touch target. Variants: `.btn-primary` (gold gradient background, dark `--primary` text, extruded shadow), `.btn-secondary` (neumorphic surface, theme text), `.btn-ghost` (border only). If any destructive action exists, `.btn-danger` must be visually distinct in both themes.\n- **Hover:** brightness\u002Fshadow shift + subtle gold glow, `cursor: pointer`.\n- **Focus:** a distinct visible `:focus-visible` ring using CSS variables (outline and\u002For box-shadow glow) — never rely on neumorphic shadow change alone.\n- **Active:** `transform: scale(0.97)`.\n- **Loading:** disables interaction and prevents double-clicks; CSS spinner or animated Material Symbol replaces\u002Foverlays the label without changing button dimensions.\n- **Disabled:** `opacity: 0.5`, greyscale, `cursor: not-allowed`.\n- **Success\u002FError:** transient feedback classes driven by `--text-success` \u002F `--text-error` with accompanying icons.\n\n**3.2 Cards**\n- **Default:** flex layout, `--bg-secondary` surface, 1px `--border-default`, `--radius-lg`, extruded shadow, consistent `--spacing-gap` padding.\n- **Hover:** elevation\u002Fglow escalation or `transform: translateY(-2px)`.\n- **Focus-within:** border\u002Fglow highlight when a child control is focused.\n- **Loading (Skeleton):** define shimmer keyframes and `.card--skeleton` styles in CSS that prevent layout jumps.\n- **Empty State:** define a reusable pattern with a large Google Icon and clear guidance text.\n\n**3.3 Forms & Inputs**\n- **Structure:** `.input-group` flex container wrapping a `\u003Clabel>`, the input, and a dedicated error feedback element (`aria-live=\"polite\"`).\n- **States:** empty, focused (inset neumorphic shadow + gold ring), filled, valid (`--border-success` + check icon), invalid (`--border-error`, error icon, error text in `--text-error`), disabled, read-only — all via classes\u002Fpseudo-classes in CSS.\n\n**3.4 Modal \u002F Popup \u002F Overlay**\n- Applies to the mobile navigation drawer and any optional dialog: opening, open, and closing states animated via CSS transitions (transform + opacity); backdrop overlay with blur and darkened layer at `--z-modal` (above `--z-dropdown`; any toasts at `--z-toast`); Material Symbol close control; keyboard focus trapping while open; close via `Esc` or backdrop click; focus returns to the trigger on close; correct roles (`dialog`\u002F`navigation`, `aria-modal` where appropriate). If you add any centered dialog, its container must use a centered flex layout (`align-items: center`) and its content states — opening, open, loading, success\u002Ferror, closing — must all be animated.\n\n---\n\n**4. CORE UX & MICRO-INTERACTION RULES**\n\n- **Responsive by default:** fluid `clamp()` typography; visuals scale via `aspect-ratio` + `max-width`; zero horizontal overflow.\n- **Smooth animations:** `transition: var(--transition-normal)` on all state changes; scroll-entrance reveals via IntersectionObserver adding a class (opacity\u002Ftranslate). All motion — drum rotation, strip pulses, reveals — must respect `@media (prefers-reduced-motion: reduce)` by becoming instant or static.\n- **Accessibility (a11y):** WCAG AA contrast in both Light and Dark modes. Never rely on color alone — pair every state with icons and text. Semantic HTML5 (`header`, `nav`, `main`, `section` with `aria-labelledby`, `footer`), logical heading hierarchy (single `h1`, `h2` per section, `h3` in cards), logical DOM\u002Ffocus order, full keyboard operability (nav, drawer, accordion, form), visible focus everywhere, a skip-to-content link, and `aria-live`\u002F`aria-busy` for dynamic feedback (form results, loading states).\n- **Mandatory visual feedback:** every hover, click, and submission triggers a visible state change.\n- **Theme integrity:** both themes must look intentionally designed — verify neumorphic relief reads correctly on cream (light) and near-black (dark, with gold-tinted highlights).\n\n---\n\n**5. DELIVERABLE & OUTPUT FORMAT**\n\n- **Files:** `index.html`, `style.css`, `script.js` — separate files. `index.html` links `style.css` and exactly one deferred entry point: `\u003Cscript src=\"script.js\" defer>\u003C\u002Fscript>`. No other inline scripts, no inline styles, no inline event handlers (`addEventListener` only).\n- **Naming:** one convention throughout — BEM (`.hero__title`, `.pricing-card__badge`, `.faq-item__button`) or one fixed utility set. Never mix conventions.\n- **JS scope (vanilla only):** theme toggle + `localStorage` persistence, mobile drawer, FAQ accordion, smooth anchor scrolling (reduced-motion aware), email validation + simulated async submit with loading\u002Fsuccess\u002Ferror, IntersectionObserver reveals. Nothing beyond this scope.\n- **Copy:** complete real English copy per 0.5; placeholders only where content was genuinely left unspecified (e.g., external footer URLs).\n- **Verification checklist before submission:** all 9 sections present and populated · both themes toggle correctly and persist · no inline styles\u002Fscripts · all button\u002Finput\u002Fcard states implemented · no horizontal scroll at 320px · keyboard-only pass completes every interaction · reduced-motion pass disables animation · no lorem ipsum.\n",1791954992622]
