Build a complete, production-ready landing page on the first attempt. The governing aesthetic is **Minimalism & Swiss**: rigorous grid discipline, generous whitespace, restrained color, precise typographic hierarchy, and zero decorative noise — expressed through a modern **Bento grid** composition for a product designer's portfolio.\n\n---\n\n## 0. PROJECT BRIEF & VISUAL DIRECTION\n\n**0.1 Theme Identity**\n- **Theme:** Bento Product Portfolio\n- **Style:** Visual, Organized, Modern\n- **Keywords:** product design, portfolio, visual, organized, modern, clean, intuitive, detailed, curated, professional\n- **Era:** 2026+ User-Centered Design\n- **Output Category:** Minimalism & Swiss\n\n**0.2 Visual Direction (mandatory)**\nDesign a visual, organized Bento-style landing page for a product designer's portfolio. Use: Bento grid layouts for project presentation; cards with project thumbnails and concise descriptions; clean sans-serif typography; minimalist process icons; project-preview hover micro-interactions; smooth, focused element transitions; light grey and medium blue accents; a detailed, professional, curated feel. Emphasis on organization and project detail throughout.\n\n**0.3 Copy Language Rule**\nAll user-facing copy must be written in **English** — concise, curated, professional tone. Write real, specific copy (project names, testimonial authors with roles\u002Fcompanies, pricing tier names and prices, FAQ questions and answers, process step titles). Lorem ipsum is prohibited.\n\n**0.4 Page Structure (sections in this exact order)**\n1. **Sticky Header:** Text logo mark, anchor nav links (Features, Process, Testimonials, Pricing, FAQ), theme toggle, mobile hamburger (Material Symbol) opening a keyboard-accessible slide-down panel with `aria-expanded`.\n2. **Hero:** Eyebrow tag, large H1, supporting subheadline, primary CTA button + secondary link, and a Bento mosaic of 4–5 project tiles (`.bento-project-card` with `.project-thumbnail`) in asymmetric spans (e.g., one 2×2, others 1×1\u002F1×2). On mobile, stack text above a single-column mosaic.\n3. **Features (3 cards):** Section header (eyebrow + H2 + description), then 3 cards in a Bento arrangement (one wide tile + two standard, or equal thirds). Each card: minimalist Material Symbol icon inside a pastel-tinted rounded square (rotate mint\u002Fpeach\u002Flavender tints), title, concise description.\n4. **How It Works (3 steps):** Three numbered steps (01\u002F02\u002F03) with minimalist process icons (e.g., `search` → `edit`\u002F`design_services` → `rocket_launch`), connected by a subtle horizontal line on desktop, stacked on mobile. Each step: number, icon, title, short description.\n5. **Testimonials:** 3 quote cards with quote icon, quote text, author name, role\u002Fcompany, and a circular avatar (seeded placeholder or CSS initials).\n6. **Pricing (3 tiers):** Three tiers (e.g., Essential \u002F Professional \u002F Studio). Middle tier visually elevated: `--primary` border, \"Most Popular\" badge, stronger shadow. Each tier: name, price + period, short description, feature list with Material Symbol check icons, CTA button (primary on middle tier, secondary\u002Foutline on others).\n7. **FAQ:** Accessible accordion with 5–6 items; first item open by default; chevron icon rotates on expand; smooth CSS height transition.\n8. **Final CTA:** Full-width Bento-style panel with headline, supporting line, and an **email capture form** (input + button) demonstrating all form states. If the panel uses a `--primary` (#6495ED) background, all text on it must be `#1B2A4A` (verified ≥4.5:1) — never white or `#333333` body text on the blue.\n9. **Footer with secondary links:** Brand blurb, grouped link columns (Work, Company, Resources), social links as text labels or generic Material Symbols (`mail`, `alternate_email`, `public` — no brand logos, no inline SVG), copyright line, back-to-top link.\n\n**0.5 Color Palette → CSS Variable Token Map**\n\nLight mode (default), defined in `:root`:\n- `--bg-primary: #F0F2F5` (Light Grey — page background; never pure white)\n- `--bg-secondary: #fefefe` (card\u002Ftile background — **explicit substitution for the palette's #FFFFFF per architecture rule 1.2**)\n- `--text-primary: #333333` · `--text-secondary: #6C757D`\n- `--primary: #6495ED` (Medium Blue — interactive accent) · `--secondary: #98FB98` (Mint Green — secondary accent, used on tags\u002Fsuccess accents, never as text on light backgrounds)\n- Pastel tile tints: `--accent-mint: #98FB98`, `--accent-peach: #FFDAB9`, `--accent-lavender: #E6E6FA` — always paired with `--text-primary` (dark text on light pastel)\n- `--text-success: #1F7A4D` (darkened Mint for AA contrast) · `--text-error: #C0392B` (accessible red; the palette contains no red, but error tokens are architecturally required)\n- `--border-default: #E2E5EA` · `--border-error: #C0392B` · `--border-success: #1F7A4D`\n- `--radius-sm: 6px` · `--radius-md: 10px` (per spec) · `--radius-lg: 16px`\n- `--shadow-sm: 0 2px 6px rgba(0,0,0,0.04)` (per spec) · `--shadow-md: 0 10px 30px rgba(0,0,0,0.08)`\n- `--spacing-gap: 1.5rem` (Bento gutter) · `--transition-fast: 150ms ease-in-out` · `--transition-normal: 300ms ease-in-out` (per spec) · `--ease-standard: ease-in-out`\n- `--z-dropdown: 10` · `--z-modal: 100` · `--z-toast: 200`\n- `--font-base: 'Inter', sans-serif`\n\nDark mode tokens (mandatory, under `.dark` and\u002For `@media (prefers-color-scheme: dark)`):\n- `--bg-primary: #17191D` · `--bg-secondary: #21252B` · `--text-primary: #F0F2F5` · `--text-secondary: #A6AEB8`\n- `--primary: #7FA8F0` (lightened Medium Blue for dark-mode contrast) · `--secondary: #98FB98`\n- Pastel tile tints become dark, desaturated surfaces paired with light text: `--accent-mint: #24463C`, `--accent-peach: #4A382A`, `--accent-lavender: #3A3653`; the original pastels may still be used as small accent colors (icons, tags) on dark backgrounds\n- `--text-success: #7FD9A4` · `--text-error: #F08A7A` · `--border-default: #343941` · `--border-error: #F08A7A` · `--border-success: #7FD9A4`\n- Shadows deepen: `--shadow-sm: 0 2px 6px rgba(0,0,0,0.4)` · `--shadow-md: 0 10px 30px rgba(0,0,0,0.5)`\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** anywhere in the HTML.\n- All design properties, layout rules, and states are targeted exclusively via class or ID selectors.\n- HTML remains clean, semantic, and style-agnostic: changing the site's look must require editing only `style.css`, never the markup.\n\n**1.2 CSS Variables (`var(--...)`) & Theme Tokens**\n- Every visual token must be stored as a CSS variable per the token map in Section 0.5 — no hardcoded hex values, radii, shadows, or durations in component rules.\n- **Contrast Pairing:** Every light background token pairs with a dark text token and every dark background token pairs with a light text token — enforced in both themes, including pastel tile tints.\n- **Light Mode Background:** The page background is `#F0F2F5`, never pure white; wherever the palette's white is needed (cards, tiles), use `#fefefe` instead of `#ffffff`.\n- Apply transitions to specific properties (`transform`, `box-shadow`, `background-color`, `color`, `border-color`) using `var(--transition-normal)` rather than blanket `transition: all`.\n\n**1.3 Mandatory Dark Mode Support**\n- Dark mode tokens must be defined under `@media (prefers-color-scheme: dark)` and\u002For a `.dark` class selector; background and text variables must switch seamlessly with zero HTML restructuring.\n- Provide a visible theme toggle in the sticky header using Material Symbols (`dark_mode` \u002F `light_mode`) with correct `aria-pressed` and `aria-label` state.\n- Persist the user's choice via `localStorage`, falling back to `prefers-color-scheme` on first visit.\n- **Exception clause:** The source style specification lists Dark Mode as excluded; per mandatory architecture, full dark mode support is nonetheless required and must be implemented exactly as defined in this section.\n\n**1.4 Flexbox Layout & Mobile-First Alignment**\n- Build all layout structures with Flexbox (`display: flex` \u002F Tailwind flex utilities). Every flex container defaults to `align-items: center` (`items-center`) unless an explicitly justified exception exists (e.g., `align-items: flex-start` for multi-line text blocks).\n- **Exception clause:** The Bento mosaics (`.bento-grid`, hero and feature arrangements) may use CSS Grid (`display: grid`) to achieve variable tile spans; every non-mosaic layout structure must use Flexbox with the `align-items: center` default.\n- Mobile-first: all layouts are responsive out of the box — Bento mosaics collapse to a single column, rows convert to columns on small viewports, and horizontal scrolling is impossible at any width.\n\n**1.5 Framework Default & Tailwind CSS Integration**\n- Use Tailwind CSS (Play CDN acceptable) unless another framework is requested; define a theme config mapping Tailwind colors\u002Ffonts to the CSS variables from Section 0.5.\n- All utility usage must map back to CSS variables or generic reusable component classes: `.btn`, `.card`, `.input-group`, plus the spec-mandated `.bento-project-card`, `.project-thumbnail`, `.preview-hover`.\n\n**1.6 Typography & Icons (Google Fonts Mandatory)**\n- Load **Inter** from Google Fonts (weights 400\u002F500\u002F600\u002F700) via `\u003Clink>` and bind it to `--font-base`. Establish clear hierarchy: large tight-tracking H1, section H2s, small uppercase letter-spaced eyebrows — Swiss typographic discipline.\n- Use **Google Material Symbols** (Rounded or Outlined) for every icon: process icons, feature icons, pricing check marks, FAQ chevrons, quote marks, theme toggle, hamburger, button arrows.\n- Raw inline SVGs, local icon files, and emoji are **explicitly forbidden**.\n\n---\n\n## 2. COMPONENT DESIGN SPECIFICATIONS\n\n**2.1 Button Component Requirements**\nStyle all states via CSS classes (`.btn`, `.btn-primary`, `.btn-secondary`, `.btn-danger`):\n- **Default:** `display: flex; align-items: center; justify-content: center; gap: 0.5rem;` minimum touch target 44×44px; Inter 600.\n- **Hover:** brightness\u002Fshadow shift with `cursor: pointer`.\n- **Focus:** distinct focus ring via `outline`\u002F`box-shadow` using `--primary` for keyboard navigation.\n- **Active\u002FPressed:** `transform: scale(0.97)` feedback.\n- **Loading (`.is-loading`):** disables interactions, prevents double-clicks, renders a CSS border spinner or animated Google Icon without distorting button dimensions.\n- **Disabled:** `opacity: 0.5`, greyscale, `cursor: not-allowed`.\n- **Success\u002FError:** temporary feedback styles driven by `--text-success` \u002F `--text-error` (e.g., CTA email form submission feedback).\n\n**2.2 Card Component Requirements (Bento Project Card)**\n- **Default:** `.bento-project-card` — tile with `--bg-secondary`, 1px `--border-default` border, `border-radius: var(--radius-md)` (10px), `box-shadow: var(--shadow-sm)`, consistent internal padding; `.project-thumbnail` uses a fixed aspect ratio (16\u002F10), `object-fit: cover`, rounded top corners, `overflow: hidden`.\n- **Hover (`.preview-hover`):** on hover and `:focus-within` — thumbnail scales to `1.05`, a gradient overlay fades in with a \"View Project\" label + arrow icon, and the card lifts (`translateY(-2px)`) with `--shadow-md`; all via `var(--transition-normal)`.\n- **Focus-within:** card border highlights with `--primary` when a child link\u002Fbutton receives focus.\n- **Loading (Skeleton):** define a shimmer keyframe animation in CSS applied to `.project-thumbnail` until the image loads (script toggles a class on the `load` event) to prevent layout jumps.\n- **Empty State:** structured fallback layout with a Google Icon and clear guidance text.\n- Feature, step, testimonial, and pricing cards reuse the `.card` base with the same state discipline.\n\n**2.3 Form & Input Requirements**\nUsed by the Final CTA email capture:\n- **States:** Empty, Focused (outline ring in `--primary`), Filled, Valid (success border + check icon), Invalid (error border, `--text-error` message, error icon), Disabled, Read-only.\n- **Structure:** flex `.input-group` wrapping a label, input field, and a dedicated error feedback container.\n- Errors are announced via `aria-live=\"polite\"` and never communicated by color alone (always icon + text).\n\n**2.4 Modal \u002F Popup Requirements**\n- No modals are required for this page; the FAQ must use the accordion pattern, not popups.\n- If you optionally add a project preview dialog triggered from a Bento tile, it must implement: centered flex container (`align-items: center`), backdrop overlay, Google Icon close button, keyboard focus trapping, close via `Esc` and overlay click, CSS-animated opening\u002Fclosing, and defined Loading and Success\u002FError states.\n\n---\n\n## 3. CORE UX & MICRO-INTERACTION RULES\n\n- **Responsive by Default:** fluid sizing and breakpoints (~640\u002F768\u002F1024px) with zero horizontal overflow; Bento mosaics reflow from multi-span tiles to a single column; use `clamp()` for fluid typography.\n- **Smooth Animations:** `transition: var(--transition-normal)` on all state changes (hovers, lifts, chevron rotations, accordion expansion, menu slide); fully respect `prefers-reduced-motion` by disabling transforms and shimmer.\n- **Swiss Discipline:** strict alignment, a consistent spacing scale, a max-width content container (~1200px), generous whitespace, and restrained color — Medium Blue used purposefully, never decoratively.\n- **Accessibility (a11y):** AA contrast in both Light and Dark modes; semantic HTML5 (`header`\u002F`nav`\u002F`main`\u002F`section`\u002F`footer`, strict h1–h3 hierarchy); correct ARIA on the accordion (`aria-expanded`, `aria-controls`), theme toggle (`aria-pressed`), and mobile menu (`aria-expanded`); logical DOM\u002Ffocus order; full keyboard operability for every interactive element; `aria-live` regions for form feedback; a skip-link to main content; smooth anchor scrolling with `scroll-margin-top` offset for the sticky header.\n- **Mandatory Visual Feedback:** every click, hover, and submission triggers a visible state change.\n- **Destructive Actions:** define `.btn-danger` as visually distinct in both themes, even if lightly used.\n- **Bento Micro-Interactions:** hover previews on project tiles, icon nudges, button press transforms, chevron rotation, and shadow elevation shifts — all smooth, focused, and subtle.\n\n---\n\n## 4. DELIVERABLE & OUTPUT FORMAT\n\n- **File Structure:** separate `index.html`, `style.css`, and `script.js`. No inline `\u003Cstyle>` blocks and no inline `\u003Cscript>` blocks beyond a single deferred `script.js` reference.\n- **Naming Convention:** one consistent convention — flat, hyphenated, descriptive class names (e.g., `.bento-project-card`, `.project-thumbnail`, `.preview-hover`, `.hero-grid`, `.feature-card`, `.step-card`, `.pricing-card`, `.faq-item`, `.footer-link`). Never mix conventions. The three spec-mandated selectors `.bento-project-card`, `.project-thumbnail`, and `.preview-hover` must exist verbatim.\n- **Copy:** all English, real, and specific to a senior product designer's portfolio — no lorem ipsum.\n- **Images:** project thumbnails and avatars via seeded placeholders (`https:\u002F\u002Fpicsum.photos\u002Fseed\u002F\u003Cname>\u002F800\u002F500`) since no real assets were provided; style them with `.project-thumbnail`.\n- **JavaScript Scope:** only theme toggle persistence, mobile menu, FAQ accordion, thumbnail load\u002Fskeleton handling, and CTA form validation\u002Ffeedback — no other behavioral code.\n- Deliver complete, runnable code on the first attempt.\n",1791954984089]
