## 1. STRICT RULES & ARCHITECTURE

### 1.1 CSS-First Architecture & Zero Inline CSS
* **No Inline CSS:** The `style="..."` attribute is forbidden anywhere in the HTML.
* **Class/ID Selectors Only:** All design properties, layout rules, and states must be targeted via class or ID selectors inside `style.css`.
* **Minimal HTML Modifications:** HTML must remain clean, semantic (header, nav, main, section, footer), and agnostic of visual styling — changing the site's look must only require editing `style.css`.

### 1.2 CSS Variables & Theme Tokens
Store all visual tokens in `:root` and the dark theme class. Use exactly these names, with these theme values:

**Light theme (`:root`):**
* Colors: `--primary: #FFD700` (Corn Yellow — fill/accent only, never text on light backgrounds), `--secondary: #6B8E23` (Herb Green), `--secondary-strong: #55771A` (darkened herb green for AA-safe fills and text), `--accent: #ED7014` (Carrot Orange — large display headings only), `--bg-primary: #FFF8E8` (warm cream), `--bg-secondary: #F6EBD9` (parchment), `--text-primary: #4A3525` (deep warm brown), `--text-secondary: #7C6A52`, `--text-success: #55771A`, `--text-error: #D14333`, `--border-default: #D2B48C` (tan; the notebook signature style is `1px dashed`), `--border-error: #D14333`, `--border-success: #6B8E23`.
* **Near-White Rule:** Where the palette specifies `#FFFFFF`, substitute `#FEFEFE` — never use pure white.
* Shape & Depth: `--radius-sm: 6px`, `--radius-md: 10px`, `--radius-lg: 22px`, `--shadow-sm: 0 2px 8px rgba(139,69,19,0.10)`, `--shadow-md: 0 8px 24px rgba(139,69,19,0.16)`.
* Motion & Space: `--spacing-gap: 1.5rem`, `--transition-fast: 0.25s ease-in-out`, `--transition-normal: 0.7s ease-in-out` (the theme's signature slow transition, used for section reveals and theme switches), `--ease-standard: ease-in-out`.
* Stacking: `--z-dropdown: 100`, `--z-modal: 200`, `--z-toast: 300`.
* Typography: `--font-base: 'Nunito', sans-serif`, `--font-handwritten: 'Caveat', cursive`.

**Contrast Pairing (mandatory in both themes):** Corn Yellow backgrounds always carry dark brown text; cream/parchment backgrounds always carry deep brown text; dark cocoa backgrounds always carry cream text. Carrot Orange is only permitted for headings at large sizes (≥ 24px, or ≥ 19px bold); body text uses `--text-primary`/`--text-secondary`.

**Signature utility classes (preserve verbatim):** `.chita-texture-bg`, `.handwritten-recipe`, `.cookbook-flip-transition`.

### 1.3 Mandatory Dark Mode Support
* **Tokens:** Define a full dark token set under both `@media (prefers-color-scheme: dark)` and a `.dark` class: `--bg-primary: #211610` (deep cocoa), `--bg-secondary: #2E2015`, `--text-primary: #F6EBDC` (cream), `--text-secondary: #C9B69C`, `--secondary: #9BC24D`, `--secondary-strong: #9BC24D` (paired with dark text), `--accent: #FF9A57`, `--text-success: #A9D46A`, `--text-error: #FF8A75`, `--border-default: #6B5138`, shadows in deep `rgba(0,0,0,0.45)`. Corn Yellow `#FFD700` is retained in dark mode, always paired with `#241A0F` text.
* **Theme Switching:** Background and text variables must switch seamlessly with no HTML restructuring; apply `--transition-normal` to `body` for a smooth cross-fade.
* **Persistence & Toggle:** Persist the user's choice via `localStorage` (falling back to `prefers-color-scheme` on first visit) and expose a visible toggle in the header with correct `aria-pressed` and `aria-label` states, swapping Google Material icons `light_mode` / `dark_mode`.
* **Exception clause:** Although the source style spec lists dark mode as excluded, dark mode is mandatory for this deliverable — implement it as a warm "night kitchen" variant (deep cocoa backgrounds, cream text, glowing corn-yellow accents) that preserves the cozy mood.

### 1.4 Flexbox Layout & Mobile-First Alignment
* Build all layout structures with Flexbox (`display: flex` / Tailwind flex utilities).
* **Default Alignment Rule:** Every flex container defaults to `align-items: center` (`items-center`) unless an explicitly justified exception is documented (e.g., pricing feature lists and footer link columns may use `flex-start` for readability — state the exception in a CSS comment).
* **Mobile-Friendly First:** Rows must convert to columns on small viewports; prevent horizontal scrolling at every breakpoint; no fixed widths that break below 360px.

### 1.5 Framework Default & Tailwind CSS Integration
* Use Tailwind CSS (Play CDN is acceptable) for layout, spacing, and responsive utilities. All visual identity (colors, borders, effects, states) must live in `style.css` as generic reusable component classes (`.btn`, `.card`, `.input-group`, etc.) driven by the CSS variables above — never hard-coded hex values inside component classes.

### 1.6 Typography & Icons (Google Fonts Mandatory)
* **Text:** Load Google Fonts via `<link>` in `<head>`: **Caveat** (handwritten headings, recipe cards, numerals) and **Nunito** (base body text). Bind them to `--font-handwritten` and `--font-base`.
* **Icons:** Use Google Material Symbols (Rounded style) via the official `<link>` tag. **Explicitly forbidden:** raw inline SVGs, local icon files, and emoji used as icons.

## 2. COMPONENT DESIGN SPECIFICATIONS

### 2.1 Button Component
Style all states via CSS classes; base `.btn`: `display: flex; align-items: center; justify-content: center; gap: 0.5rem;` minimum touch target 44×44px, `border-radius: var(--radius-md)`, `transition: var(--transition-fast)`.
* **Variants:** `.btn--primary` (Corn Yellow bg, dark brown text), `.btn--secondary` (Herb Green `--secondary-strong` bg, cream text; in dark mode brightened green bg with dark text), `.btn--outline` (transparent, herb green border + text, fills on hover), `.btn--danger` (darkened tomato `#D14333` bg with cream text in light mode; `#FF6347` bg with very dark brown text in dark mode — visually distinct in both themes).
* **Hover:** brightness shift + `--shadow-md`, `cursor: pointer`.
* **Focus:** distinct `:focus-visible` ring using `--primary` at ~45% alpha (3px offset) — never remove outlines without replacement.
* **Active/Pressed:** `transform: scale(0.97)`.
* **Loading (`.is-loading`):** disables pointer events, prevents double-clicks, swaps the label for a rotating Material `progress` icon or CSS spinner **without changing button dimensions**; set `aria-busy="true"`.
* **Disabled:** `opacity: 0.5`, greyscale filter, `cursor: not-allowed`, no hover/active effects.
* **Success/Error (`.is-success`, `.is-error`):** transient feedback states using `--text-success` / `--text-error` borders **plus** a check or error Material icon — never color alone.

### 2.2 Card Component
Base `.card`: Flexbox layout, `--bg-secondary` background, `1px dashed var(--border-default)` border, `--radius-md`, `--shadow-sm`, generous padding.
* **Hover:** `transform: translateY(-2px)` + elevation shift to `--shadow-md` + border color shift toward `--secondary`.
* **Focus-within:** card border highlights (`--accent`) when a child link/button receives focus.
* **Loading (Skeleton):** define `.card--skeleton` shimmer animation (gradient sweep) with reserved min-heights to prevent layout jumps.
* **Empty State:** define a structured fallback with a centered Material icon (`menu_book`) and clear guidance text.

### 2.3 Form & Input Requirements
Structure: `.input-group` as a flex column wrapping a `<label>`, an `.input-field` wrapper (input + validation icon), and a dedicated error message container with reserved min-height and `aria-live="polite"`.
* **States to style:** Empty, Focused (herb green border + corn yellow ring), Filled, Valid (`--border-success` + `check_circle` icon), Invalid (`--border-error` + `error` icon + red message text), Disabled, Read-only (dashed border, muted background). Inputs: min-height 44px, `--radius-md`.

### 2.4 Modal / Popup — "Share Your Recipe" Dialog
Triggered by the Hero's primary CTA. Overlay: fixed, `rgba(42,26,12,0.55)` + subtle backdrop blur, `display: flex; align-items: center; justify-content: center;`, `z-index: var(--z-modal)`. Panel: `--bg-primary`, dashed tan border, `--radius-lg`, max-width 480px.
* **States:** Opening (fade + scale 0.95→1), Open, Loading (submit button enters `.is-loading` for a simulated ~1.2s), Success (check icon + "Your recipe is on the table!" message, auto-closes), Closing (reverse animation).
* **UX Features:** Material `close` icon button (44px target, `aria-label="Close dialog"`), keyboard focus trap, `Esc` and overlay-click closing, focus returned to the trigger, `role="dialog"` + `aria-modal="true"` + `aria-labelledby`. Contains a short form (name, recipe title, email) exercising all Section 2.3 states.

### 2.5 Toast / Live Feedback
Define a fixed toast region (`aria-live="polite"`, `z-index: var(--z-toast)`) with success and error variants (icon + message), slide-up entrance, ~3.5s auto-dismiss, used for form submissions and modal confirmations.

## 3. CORE UX & MICRO-INTERACTION RULES

### 3.1 Global UX Rules
* **Responsive by Default:** fluid sizing, no horizontal overflow, sections stack on mobile.
* **Smooth Animations:** CSS transitions on all state changes; use `--transition-fast` for interactive controls and `--transition-normal` (the spec's `all 0.7s ease-in-out`) for section reveals and theme changes. Fully respect `prefers-reduced-motion` (disable steam, flip transforms, and shimmer; reduce transitions to near-zero).
* **Accessibility (a11y):** AA contrast in both themes; never rely on color alone; semantic HTML5; correct ARIA roles/labels on the accordion, modal, toggle, and mobile menu; logical focus order; full keyboard operability; a "Skip to content" link; `aria-live` for all dynamic feedback.
* **Mandatory Visual Feedback:** every click, hover, and submission triggers a visible state change.
* **Destructive Actions:** `.btn--danger` must be visually distinct in both light and dark themes.

### 3.2 Theme-Specific Effects (all CSS-only, no external assets)
* **Chita Texture (`.chita-texture-bg`):** Simulate the floral chita print with layered `repeating-linear-gradient` / `repeating-radial-gradient` patterns (small corn-yellow, tomato-red, and sky-blue floral dots on a cream base), kept subtle and low-contrast so text remains readable; provide a muted dark-mode variant. Apply to the Hero backdrop band, the Final CTA band, and the footer's top edge.
* **Steam / Aroma Hover:** On `.card` hover (feature cards especially), animate `::before`/`::after` pseudo-elements — blurred, semi-transparent warm-white radial gradients rising upward with opacity keyframes — evoking steam or aroma. Infinite while hovered; disabled under reduced motion.
* **Cookbook Flip (`.cookbook-flip-transition`):** Sections begin slightly rotated (`perspective` + `rotateY(-8deg)` + `translateY`) at 0 opacity and settle to normal over `--transition-normal` when scrolled into view (IntersectionObserver adds `.is-visible`). Under reduced motion, degrade to a simple fade. No layout shift.
* **Handwritten Recipe (`.handwritten-recipe`):** Caveat typography, notebook ruled-line background via `repeating-linear-gradient`, `1px dashed #D2B48C` border, `border-radius: 10px`, a slight `-1deg` rotation, and an optional washi-tape strip via pseudo-element.
* **Dish "Photos":** No external image files — build warm gradient placeholder frames styled as polaroid/recipe cards with a Material Symbol (`soup_kitchen`, `restaurant`, `bakery_dining`) and a Caveat caption.

Hover triggers lift + steam wisps.

### 4.3 How It Works — 3 Steps
Horizontal on desktop with a dashed tan connector line behind, vertical stack on mobile. Each step: large Caveat numeral in a corn-yellow circle, Material icon, title, copy:
1. `edit` — "Write It Down" — "Jot your recipe onto a handwritten-style card — ingredients, steps, and that secret touch."
2. `history_edu` — "Season It with Memory" — "Add the story behind the dish: who taught it, when it's served, why it matters."
3. `dinner_dining` — "Set the Table Together" — "Publish it to the community, cook along with others, and pass the flavor forward."

### 4.4 Testimonials
Three `.card` quotes with `format_quote` icon, five `star` icons (with an accessible "Rated 5 out of 5" label), gradient initial avatar, name + city:
* "Maria C. — Belo Horizonte": "I posted my mother's pão de queijo recipe with her story. A stranger cooked it and thanked me crying. This place is a hug."
* "João P. — Recife": "The handwritten cards make me feel like I'm reading my grandma's notebook again. I cook more now than I have in years."
* "Ana L. — São Paulo": "Every Sunday our community table cooks one recipe together. It's the warmest corner of the internet I know."

## 5. DELIVERABLE & OUTPUT FORMAT

* **File Structure:** Separate `index.html`, `style.css`, and `script.js`. No inline `<script>` blocks beyond a single deferred `script.js` entry point; Google Fonts, Material Symbols, and Tailwind CDN references go in `<head>`.
* **Naming Convention:** BEM (`block__element--modifier`) for all components, with `.is-*` state classes — plus exactly three standalone utility classes preserved verbatim: `.chita-texture-bg`, `.handwritten-recipe`, `.cookbook-flip-transition`. Never mix in other conventions.
* **Copy:** All user-facing copy in English, warm and community-toned, matching the content specified in Section 4 — no lorem ipsum. Brazilian dish names (feijoada, pão de queijo, brigadeiro) may appear as proper nouns.
* **JavaScript Scope:** theme toggle with `localStorage` persistence, mobile menu, FAQ accordion, IntersectionObserver reveals, modal with focus trap, form validation, toasts, and button loading states — all in `script.js`, no behavioral logic in HTML.
* **First Attempt Complete:** Ship the full landing page in one response — both themes verified for contrast, all states implemented, fully keyboard operable, responsive from 360px up.
