## 1. STRICT RULES & ARCHITECTURE

**1.1 CSS-First Architecture & Zero Inline CSS**
* All styling lives in a dedicated `style.css`. **Forbidden:** any `style="..."` attribute in the HTML.
* All design properties, layout rules, and states are applied exclusively via class/ID selectors.
* HTML must remain semantic and styling-agnostic: changing the look requires editing only `style.css`, never the markup.

**1.2 CSS Variables & Theme Tokens**
* Use the provided token block as the canonical `:root` system: `--color-bg: #fbf1de`, `--color-surface: #fff8ec`, `--color-surface-2: #f3e2bf`, `--color-text: #3a2317`, `--color-text-muted: #6b4a35`, `--color-primary: #d63b2f`, `--color-accent: #2f7a63`, `--color-mustard: #e0a629`, `--color-outline-ink: #2b1a10`, plus the given radius, shadow, font, text, space, and ease tokens, `--motif-border`, and `--outline-stroke`.
* **Refactor all hardcoded hex values** in `--shadow-outline`, `--shadow-outline-sm`, `--motif-border`, and component rules (e.g., `.btn--primary` color, `.badge` color) to reference `var(--color-*)` tokens so every theme switch propagates automatically.
* **Add these mandatory semantic tokens** alongside the given set: `--color-success` (suggested `#27654f` light / `#6fbf9e` dark), `--color-error` (suggested `#b3261e` light / `#ff9d94` dark), `--border-default`, `--border-error`, `--border-success`, `--spacing-gap: 16px`, `--transition-fast: 120ms`, `--transition-normal: 240ms` (both consuming `--ease-standard`), `--z-dropdown: 100`, `--z-modal: 1000`, `--z-toast: 1100`.
* **Contrast pairing:** every light background token pairs with a dark text token and vice versa, in **both** themes. Never use pure `#ffffff`; use `#fefefe` where a near-white is required.

**1.3 Mandatory Dark Mode**
* The source spec does not declare modes — **you must design and validate both Light and Dark before publishing.**
* Define dark tokens under both `@media (prefers-color-scheme: dark)` and a `.dark` class on `<html>`. Suggested starting values (verify contrast, adjust as needed): `--color-bg: #241811`, `--color-surface: #2f2015`, `--color-surface-2: #3d2b1c`, `--color-text: #fbf1de`, `--color-text-muted: #d6bd9c`, `--color-primary: #e2574b`, `--color-accent: #4da587`, `--color-mustard: #e6b04a`, and **`--color-outline-ink: #f3e2bf`** — the thick hand-drawn outlines and hard offset shadows must flip to warm cream in dark mode so they remain visible.
* **Theme toggle:** a visible button in the nav using Google Material Symbols `light_mode` / `dark_mode`, with correct `aria-pressed` and `aria-label` ("Switch to dark theme" / "Switch to light theme"). Persist choice in `localStorage`; fall back to `prefers-color-scheme` on first visit. Apply the stored theme as the first statement executed in `script.js` to minimize flash. Switching must require zero HTML restructuring.
* **Contrast validation (mandatory):** verify every text/background pair meets WCAG AA (4.5:1 normal, 3:1 large) in both modes. Cream text (`#fff8ec`) on `#d63b2f` measures ~4.4:1 — if it fails, darken the red used behind text (e.g., `#c43227` for nav and `.btn--primary` backgrounds) rather than shipping a failing pair.

**1.4 Flexbox Layout & Mobile-First Alignment**
* Build all layout structures with Flexbox. **Every flex container defaults to `align-items: center`** unless an exception is explicitly justified in a CSS comment (permitted exception: `align-items: stretch` for equal-height card columns).
* Mobile-first: rows convert to columns on small viewports (stack under 768px), fluid sizing, and **zero horizontal scrolling** at any width.

**1.5 Styling Approach**
* The provided custom CSS design system **is** the framework for this build — extend it; do not introduce Tailwind or other frameworks. All component classes (`.btn`, `.card`, `.input`, `.badge`, `.nav`) must consume the CSS variables; no magic numbers.

**1.6 Typography & Icons (Google Fonts Mandatory)**
* Load **Fredoka** (base) and **Baloo 2** (display) from Google Fonts via `<link>` with `preconnect`; bind them to `--font-sans` and `--font-display`. Headlines use Baloo 2; body uses Fredoka.
* Icons: **Google Material Symbols (Rounded variant)** via the standard `<link>`. **Explicitly forbidden:** inline SVGs, local icon files, and emoji used as icons. Fitting icon names include `local_florist`, `agriculture`, `handyman`, `workspace_premium`, `favorite`, `star`, `check`, `close`, `menu`, `mail`, `arrow_forward`, `light_mode`, `dark_mode`.

## 2. COMPONENT DESIGN SPECIFICATIONS

**2.1 Button Component (`.btn`, `.btn--primary`, `.btn--secondary`, `.btn--danger`)**
* **Default:** `display: flex; align-items: center; justify-content: center; gap: 0.5rem;` minimum touch target 44×44px, thick ink border, hard offset shadow (`--shadow-outline`).
* **Hover:** `transform: translateY(-2px)` with shadow growth; `cursor: pointer`.
* **Focus:** distinct `:focus-visible` ring using `--color-mustard` with ink outline offset.
* **Active/Pressed:** `transform: translateY(2px)` collapsing to `--shadow-outline-sm` (the "carved stamp" press).
* **Loading:** disables interaction and double-clicks; renders a CSS spinner or rotating Material Symbol **without changing button dimensions**.
* **Disabled:** `opacity: 0.5`, greyscale, `cursor: not-allowed`, no transform.
* **Success/Error:** temporary feedback states (check icon + tint for success; error icon + `--color-error` tint) driven by `--color-success` / `--color-error`.
* **`.btn--danger`:** visually distinct in both light and dark themes.

**2.2 Card Component (`.card`)**
* **Default:** flexbox layout, `--color-surface` background, `--outline-stroke` border, `--radius-lg`, and the 8px `--motif-border` strip via `::before`.
* **Hover:** `transform: translateY(-2px)` plus shadow shift.
* **Focus-within:** border/ring highlights when a child link or button receives focus.
* **Loading (Skeleton):** define a shimmer animation class in CSS that preserves layout dimensions.
* **Empty State:** structured fallback pattern with a Material Symbol and clear guidance text, available for reuse.

**2.3 Form & Input Requirements (`.input-group`, `.input`, `.input-message`)**
* **States:** empty, focused (mustard ring), filled, valid (success border + check icon), invalid (error border, error text, error icon, message), disabled, read-only.
* **Structure:** flex column wrapping a `<label>`, the input, and a dedicated `.input-message` container wired to an `aria-live="polite"` region. Never communicate errors by color alone — always icon + text.

**2.4 FAQ Accordion & Overlays**
* **FAQ:** each item is a `<button aria-expanded>` controlling a panel (`aria-controls`, `role="region"`). Panels animate open/closed via CSS only (e.g., `grid-template-rows` transition); a `expand_more` Material Symbol rotates. Fully keyboard operable; one panel open at a time; respects `prefers-reduced-motion`.
* **Toast/feedback layer:** any dynamic confirmation renders in an `aria-live` region at `--z-toast`. If any modal dialog is used, it must be centered via flex, sit above a backdrop at `--z-modal`, trap focus, close on `Esc` and overlay click, and animate open/close in CSS.

## 3. CORE UX & MICRO-INTERACTION RULES

* **Responsive by default:** fluid type via the `--text-*` scale, no horizontal overflow, `scroll-margin-top` on sections to offset the sticky nav.
* **Smooth animations:** all state changes transition with `var(--transition-normal)` and the bouncy `--ease-standard`; **`prefers-reduced-motion` disables all transforms, transitions, shimmer, and smooth scrolling.**
* **Accessibility (a11y):** AA contrast in both modes (validated per 1.3); semantic HTML5 landmarks (`header`, `main`, `section`, `footer`); a skip-to-content link; logical focus order; full keyboard operability; `aria-live` for all dynamic feedback; never color-only state communication.
* **Mandatory visual feedback:** every click, hover, and submission triggers a visible state change.
* **Effects:** the signature look is flat color with hard offset "carved" shadows and thick ink outlines. Use `blur` sparingly (at most a subtle `backdrop-filter` on the sticky nav); never introduce gradients-as-depth, gloss, or photographic realism — the aesthetic is deliberately flat.

## 4. DELIVERABLE & OUTPUT FORMAT

* **Files:** separate `index.html`, `style.css`, `script.js`. Exactly one `<script src="script.js" defer></script>` — no inline scripts, no inline styles.
* **Naming:** strict BEM (`block__element--modifier`), consistent with the provided `.btn--primary` convention. Never mix conventions.
* **Copy:** invent a coherent fictional brand fitting the theme (e.g., a handcrafted-goods marketplace or folk-craft school) and write **complete, real English copy** in a warm, plain-spoken, handmade voice across all sections. **No lorem ipsum.** No unrequested placeholders.
* **JS scope:** behavior only — theme toggle with persistence, FAQ accordion, smooth anchor navigation, email form validation with loading→success/error flow, mobile nav handling. No styling logic in JS.

## 5. THEME DIRECTION — FOLK ART / NAIVE ART

* **Signature move:** flattened perspective with zero photographic realism; bold, saturated flat color fields; thick, confident 3px hand-drawn ink outlines; decorative repeating motifs (flowers, animals, everyday farm scenes); warm handmade charm.
* **Motifs in pure CSS (no images, no SVG):** quilt-strip bands via `repeating-linear-gradient` (use `--motif-border`); hex-sign rosettes via layered `repeating-conic-gradient` / `radial-gradient` circles with thick ink borders; scalloped edges via `radial-gradient` repeats; dashed "stitch" dividers via dashed borders; flat CSS-shape scenes (sun, hills, barn, flowers) built from simple bordered blocks.
* **Color usage:** red (`--color-primary`) for nav and primary CTAs, mustard for secondary buttons and highlights, accent green for badges/success, cream surfaces for cards — all flat, never shaded.

---

## 6. SECTION-BY-SECTION SPECIFICATION

* **Nav (sticky):** red bar with ink bottom border and motif strip (`::after`), Baloo 2 brand wordmark, anchor links to all sections, theme toggle (per 1.3), and a `.btn` CTA. On mobile, links wrap or collapse behind an accessible `menu` toggle (`aria-expanded`) at `--z-dropdown` — never overflow horizontally.
* **Hero:** display headline in Baloo 2, warm subcopy, primary + secondary CTAs, a badge, and a flat CSS hex-sign rosette / farm-scene composition; repeating flower motif strip as a section divider.
* **Features (3 cards):** `.card` blocks, each with a circular Material Symbol medallion (thick ink border, alternating flat colors), title, and copy; hover lift and focus-within per 2.2.
* **How It Works (3 steps):** numbered medallions (CSS circles with ink outline and Baloo 2 numerals) connected by a dashed stitch line; stacks vertically on mobile.
* **Testimonials:** 3 quote cards with 5-star ratings rendered as `star` Material Symbols, quote, name/role, and initial-medallion avatars (no photos).
* **Pricing (3 tiers):** `.card` tiers with price, feature list using `check` icons, and per-tier CTAs; the middle tier is featured — mustard or `--color-surface-2` background, "Most Popular" `.badge`, stronger shadow/elevation.
* **FAQ:** 5–6 items per the accordion spec in 2.4.
* **Final CTA:** full-width band with motif borders, headline, and an email-capture `.input-group` (label + input + button) implementing every state in 2.1/2.3, with `aria-live` feedback and a loading→success/error button sequence.
* **Footer:** `--color-surface-2` band with ink top border and motif strip; brand blurb, 3–4 columns of secondary links (Product, Company, Support, Legal), social links as labeled Material Symbol icon buttons, and small print. Stacks to a single column on mobile.
