Your task is to code a complete, production-ready Landing Page on the first attempt. Follow every rule in this specification without deviation. **All user-facing copy must be written in English.**\n\n**Project Brief:**\n- **Theme:** HealthTech Clinical Platform — a clean, trustworthy, accessible clinic portal \u002F digital health SaaS landing page (2020s HealthTech era).\n- **Sections (in this exact order):** Hero, Features (3 cards), How It Works (3 steps), Testimonials, Pricing (3 tiers), FAQ, Final CTA, Footer with secondary links.\n- **Style Keywords:** healthtech landing, medical icons, clinic portal, healthcare green, patient journey, appointments, doctors, trust, clean, accessible, digital health.\n- **Visual Direction:** organic shapes (soft curves) as section separators; heartbeat pulse animation (`@keyframes heartbeat`, scale pulse); form fields with highlighted focus state (green border + green shadow); \"How It Works\" rendered as numbered steps.\n- **Base Aesthetic Tokens:** border-radius 12px; box-shadow `0 2px 8px rgba(0,0,0,0.08)`; text `#1A1A1A` on light backgrounds; font Inter.\n\n---\n\n## 1. STRICT RULES & ARCHITECTURE\n\n**1.1 CSS-First Architecture & Zero Inline CSS**\nKeep all styling strictly inside a dedicated `style.css` file:\n- **No Inline CSS:** Explicitly forbid the `style=\"...\"` attribute anywhere in the HTML.\n- **Class\u002FID Selectors Only:** All design properties, layout rules, and states must be targeted via class or ID selectors.\n- **Minimal HTML Modifications:** HTML must remain clean, semantic (HTML5 landmarks: `header`, `nav`, `main`, `section`, `footer`), and agnostic of visual styling — changing the site's look must require modifying only the CSS file, never the markup.\n\n**1.2 CSS Variables (`var(--...)`) & Theme Tokens**\nStore all visual tokens in `:root` (and theme classes):\n- **Colors:** `--primary` (emerald green, healthcare palette — e.g., the `#10b981` emerald family), `--secondary`, `--bg-primary`, `--bg-secondary`, `--text-primary` (`#1A1A1A` in light mode), `--text-secondary`, `--text-success`, `--text-error`, `--border-default`, `--border-error`, `--border-success`.\n- **Contrast Pairing:** Light background tokens must pair with dark text tokens, and dark background tokens with light text tokens — enforced for every theme, not just the default.\n- **Light Mode Background:** Do NOT use pure `#ffffff`. Use a warm neutral \u002F green-tinted near-white (e.g., `#f7faf9`) for `--bg-primary`, and `#fefefe` (never `#ffffff`) for near-white surfaces such as cards — the source spec's `#FFFFFF` is overridden by this rule.\n- **Radius & Shadows:** `--radius-sm`, `--radius-md: 12px`, `--radius-lg`, `--shadow-sm`, `--shadow-md: 0 2px 8px rgba(0,0,0,0.08)`.\n- **Spacing & Transitions:** `--spacing-gap`, `--transition-fast`, `--transition-normal`, `--ease-standard`.\n- **Elevation\u002FStacking:** `--z-dropdown`, `--z-modal`, `--z-toast` to prevent overlap conflicts between layered components.\n\n**1.3 Mandatory Dark Mode Support**\nDark Mode must always be defined:\n- **Implementation:** Provide dark mode color tokens under both `@media (prefers-color-scheme: dark)` and a `.dark` class selector. Background and text CSS variables must switch seamlessly with no HTML restructuring.\n- **Persistence:** Persist the user's theme choice via `localStorage`, falling back to `prefers-color-scheme` on first visit; include a visible toggle control with correct `aria-pressed` \u002F `aria-label` state.\n- **Dark Palette:** Deep neutral backgrounds (never pure black), softened emerald accents, and text tokens maintaining WCAG-compliant contrast.\n- **Exception clause:** The source style spec listed Dark Mode as unsupported (\"✗ No\"); per mandatory architecture rules this is overridden — Dark Mode must be fully implemented regardless.\n\n**1.4 Flexbox Layout & Mobile-First Alignment**\nBuild all layout structures with Flexbox (`display: flex` \u002F Tailwind flex utilities):\n- **Default Alignment Rule:** Every flex container must default to `align-items: center` (`items-center`) unless an explicitly justified exception is documented in a CSS comment.\n- **Mobile-Friendly First:** All flex layouts must be mobile-responsive out of the box — multi-column rows convert to columns on smaller viewports; no horizontal scrolling at any breakpoint; fluid sizing throughout.\n\n**1.5 Framework Default & Tailwind CSS Integration**\n- Use Tailwind CSS (or clean custom CSS driven by Tailwind's `@layer` \u002F `@apply` directives).\n- All utility classes must map back to CSS variables or generic reusable class names (`.btn`, `.card`, `.input-group`).\n\n**1.6 Typography & Icons (Google Fonts Mandatory)**\n- **Text:** Load **Inter** from Google Fonts via `\u003Clink>` or `@import` and bind it to `--font-base`.\n- **Icons:** Use **Google Material Symbols** exclusively for all iconography (e.g., `calendar_month`, `medical_services`, `verified_user`, `favorite`, `monitor_heart`, `health_and_safety`, `chat`, `shield_lock`, `check_circle`, `person`). Explicitly forbid raw inline SVGs and local icon files for icons.\n- **Exception clause:** Inline SVG is permitted exclusively for the decorative organic curve separators between sections; it remains strictly forbidden for icons. Separators must carry `aria-hidden=\"true\"` and `focusable=\"false\"`.\n\n---\n\n## 2. COMPONENT DESIGN SPECIFICATIONS\n\n**2.1 Button Component Requirements**\nStyle all states via CSS classes:\n- **Default:** `display: flex; align-items: center; justify-content: center; gap: 0.5rem;` minimum touch target 44×44px. Primary variant: filled emerald. Secondary variant: outlined\u002Fghost.\n- **Hover:** Visual shift (brightness\u002Fshadow) with `cursor: pointer`.\n- **Focus:** Distinct focus ring using CSS variables — for this theme, a green border + green shadow ring per the visual direction.\n- **Active\u002FPressed:** `transform: scale(0.97)`.\n- **Loading:** Disables interactions, prevents double-clicks, and renders a CSS spinner or animated Google Icon without distorting button dimensions.\n- **Disabled:** `opacity: 0.5`, greyscale, `cursor: not-allowed`.\n- **Success\u002FError:** Temporary feedback state styles driven by `--text-success` or `--text-error`.\n- `.btn-danger` must be visually distinct in both light and dark themes.\n\n**2.2 Card Component Requirements**\nApplies to Features (3 cards), Testimonials, and Pricing tiers:\n- **Default:** Flexible Flexbox layout, `--bg-secondary` surface, subtle `--border-default` border, `--radius-md` (12px), `--shadow-sm` elevation.\n- **Hover:** Elevation\u002Fshadow shift plus subtle `transform: translateY(-2px)`.\n- **Focus-within:** Card borders highlight when a child link\u002Fbutton receives focus.\n- **Loading (Skeleton):** Shimmer animation styling defined in CSS to prevent layout jumps.\n- **Empty State:** Structured fallback layout featuring a Google Icon and clear guidance text.\n\n**2.3 Form & Input Requirements**\nUsed in the Hero lead\u002Fappointment mini-form and the Final CTA signup:\n- **States:** Empty, Focused (green border + green shadow ring), Filled, Valid (success border\u002Ficon), Invalid (error border, red text, error icon), Disabled, Read-only.\n- **Structure:** Flex container wrapping a label, input field, and a dedicated error feedback container.\n- Error\u002Fsuccess feedback must be announced via an `aria-live` region; never communicate state by color alone — pair icons and text with state colors.\n\n**2.4 Modal \u002F Popup Requirements**\nIf a \"Book a Demo\" \u002F appointment modal is triggered from any CTA:\n- **States:** Opening, Open, Loading, Success\u002FError, Closing — all animated via CSS transitions.\n- **UX Features:** Centered flex container (`align-items: center`), backdrop overlay, Google Icon close button, keyboard focus trapping, close via `Esc` or overlay click, correct ARIA (`role=\"dialog\"`, `aria-modal=\"true\"`).\n\n**2.5 Landing Page Section Specifications**\n- **Hero:** Headline + subheadline centered on the patient journey \u002F appointments value proposition; primary CTA (\"Book an Appointment\" or \"Start Free Trial\"); secondary CTA (\"Watch Demo\" \u002F \"Talk to Sales\"); trust signals (e.g., \"HIPAA-ready security\", doctor count, patient rating); optional appointment mini-form per 2.3. Include a heartbeat pulse accent (animated Google `favorite` or `monitor_heart` icon) that respects `prefers-reduced-motion`.\n- **Features (3 cards):** e.g., Online Appointment Scheduling, Secure Patient Records, Doctor–Patient Messaging — each card pairs a Google Material Symbol icon with a title and short description; card specs per 2.2.\n- **How It Works (3 steps):** Numbered step layout (1. Create your account → 2. Book your appointment → 3. Attend your consultation) with a connecting visual line\u002Fprogress indicator; each step pairs a Google Icon with a title and one-line description; steps stack vertically on mobile.\n- **Testimonials:** 3 cards with a quote, name, role (e.g., \"Cardiologist\", \"Clinic Manager\"), and avatar (Google Icon `person` or initial — no external images required).\n- **Pricing (3 tiers):** e.g., Basic (Free), Professional (Recommended), Enterprise — each with a price, feature list using `check_circle` icons, and a CTA button; the recommended tier is visually elevated (distinct border, \"Recommended\" badge, stronger shadow).\n- **FAQ:** 5–6 realistic questions implemented as an accessible accordion — each item is a `\u003Cbutton>` with `aria-expanded`, answer panels animated via CSS transitions, full keyboard operability.\n- **Final CTA:** Full-width emerald section with headline, supporting line, and an email signup form (per 2.3) or a prominent CTA button; high-contrast text pairing per 1.2.\n- **Footer:** Secondary links (About, Features, Pricing, FAQ, Contact, Privacy Policy, Terms), social icons via Material Symbols, copyright line; semantic `\u003Cfooter>` landmark.\n\n---\n\n## 3. CORE UX & MICRO-INTERACTION RULES\n\n- **Responsive by Default:** Fluid sizing and responsive breakpoints without horizontal overflow; all multi-column layouts collapse to a single column on mobile.\n- **Smooth Animations:** `transition: var(--transition-normal)` on all state changes; the heartbeat `@keyframes` (scale pulse) and skeleton shimmer must be disabled under `prefers-reduced-motion`.\n- **Accessibility (a11y):** Sufficient contrast in both Light and Dark modes; never rely solely on color to communicate state; semantic HTML5 elements; correct ARIA roles\u002Flabels on the accordion, modal, theme toggle, and any custom widgets; logical DOM\u002Ffocus order; full keyboard operability (no mouse-only interactions); `aria-live` regions for form errors, loading states, and dynamic feedback.\n- **Mandatory Visual Feedback:** Every user click, hover, or submission must trigger a visible state change (buttons per 2.1; form submissions show loading → success\u002Ferror states).\n- **Destructive Actions:** Any destructive action must use `.btn-danger` and be visually distinct in both light and dark themes.\n- **Organic Separators:** Curve separators must be purely decorative (`aria-hidden=\"true\"`), layered behind content using the `--z` tokens, and must never trap focus or interfere with scroll\u002Freading order.\n\n---\n\n## 4. DELIVERABLE & OUTPUT FORMAT\n\n- **File Structure:** Separate `index.html`, `style.css`, and `script.js` files. No inline `\u003Cscript>` blocks beyond a single deferred entry-point reference; no inline CSS anywhere.\n- **Naming Convention:** Enforce one consistent class-naming convention (BEM or a fixed Tailwind utility set) across the entire deliverable — never mix conventions.\n- **Copy Quality:** No lorem-ipsum-only submissions — write realistic, complete English copy for every section (headlines, feature descriptions, step titles, testimonial quotes with names\u002Froles, pricing tiers with features and prices, FAQ questions and answers, CTAs, footer links). Placeholders are allowed only where content was genuinely left unspecified.\n- **First-Attempt Completeness:** Deliver the full, working landing page in one response — all eight sections built, all component states styled, dark mode functional, and the theme toggle persisted.\n",1791954980035]
