## 2. VISUAL DIRECTION

**2.1 Core Concept:** Modular grid layouts inspired by azulejo tiles; geometric elements that rotate and combine; clean modern sans-serif typography; abstract vector icons; hover micro-interactions that change a tile's pattern or color; section transitions with a module "assembly" effect.

**2.2 Azulejo Patterns via Pure CSS:** Build all tile patterns exclusively with CSS gradients (`repeating-linear-gradient`, `conic-gradient`, `radial-gradient`) — no image assets for patterns.

**2.3 Canonical Theme Classes (mandatory):** `.azulejo-grid` (modular tile grid container), `.geometric-module` (individual tile/module), `.pattern-rotate-hover` (hover modifier: tile rotates and swaps pattern/color). Integrate these names into the BEM system defined in Section 7.2.

**2.4 CSS Baseline (from spec, adapted):** background `#fefefe`, color `#000000`, borders `1px solid #E0E0E0`, base radius `4px`, font `Inter`, transitions `all 0.3s ease-in-out`.
* **Exception clause:** The source specification lists `#FFFFFF` as the background; per mandatory theme rules, use `#fefefe` for every white/near-white background — never `#ffffff`.

## 3. STRICT RULES & ARCHITECTURE

**3.1 CSS-First Architecture & Zero Inline CSS**
* All styling lives in `style.css`. **Forbidden:** `style="..."` attributes in HTML.
* All design properties, layout rules, and states are targeted via class/ID selectors only.
* HTML remains clean, semantic, and style-agnostic — retheming must require CSS edits only, never markup changes.

**3.2 CSS Variables & Theme Tokens** — define in `:root`:
* **Colors:** `--primary: #0047AB` (Cobalt Blue), `--secondary: #FFD700` (Sun Yellow), `--bg-primary: #fefefe`, `--bg-secondary: #F0F0F0` (Light Gray), `--text-primary: #000000`, `--text-secondary: #6C757D` (Medium Gray), `--text-success: #2ECC40` (Emerald Green), `--text-error: #FF6F61` (Coral Red), `--border-default: #E0E0E0`, `--border-error: #FF6F61`, `--border-success: #2ECC40`, plus accents `--accent-yellow: #FFD700`, `--accent-green: #2ECC40`, `--accent-coral: #FF6F61`.
* **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.
* **Shape & elevation:** `--radius-sm: 4px`, `--radius-md: 8px`, `--radius-lg: 16px`, `--shadow-sm`, `--shadow-md` (soft, cobalt-tinted).
* **Spacing & motion:** `--spacing-gap`, `--transition-fast: 0.15s ease-in-out`, `--transition-normal: all 0.3s ease-in-out`, `--ease-standard: ease-in-out`.
* **Stacking:** `--z-dropdown: 100`, `--z-modal: 200`, `--z-toast: 300`.
* **Typography:** `--font-base: 'Inter', sans-serif`.

**3.3 Mandatory Dark Mode Support**
* **Exception clause:** The source style specification requested light-mode-only support; Dark Mode is nonetheless mandatory and must be fully implemented.
* Provide dark tokens under both `@media (prefers-color-scheme: dark)` and a `.dark` class. Suggested dark palette (verify WCAG AA 4.5:1 text contrast): `--bg-primary: #0B1220`, `--bg-secondary: #16233D`, `--text-primary: #F0F0F0`, `--text-secondary: #A8B3C5`, `--primary: #4D8DFF` (lightened cobalt), `--border-default: #2A3A5C`; retain yellow/green/coral accents adjusted for contrast.
* Theme switching swaps variables only — no HTML restructuring.
* Persist the user's choice via `localStorage`, falling back to `prefers-color-scheme` on first visit; include a visible toggle in the header with correct `aria-pressed`/`aria-label` state and Material Symbols sun/moon icons.

**3.4 Flexbox Layout & Mobile-First Alignment**
* Build all layout structures with Flexbox (CSS Grid permitted only where a true grid is semantically required, e.g., `.azulejo-grid`).
* Every flex container **defaults to `align-items: center`** unless an exception is explicitly justified.
* Mobile-first: rows collapse to columns on small viewports; zero horizontal scrolling at any width.

**3.5 Framework Default**
* Use Tailwind CSS, or clean custom CSS organized with `@layer`/`@apply` — either way, every utility must map back to the CSS variables or generic reusable classes (`.btn`, `.card`, `.input-group`). Do not mix approaches.

**3.6 Typography & Icons (Google Fonts Mandatory)**
* Load **Inter** (weights 400–800) from Google Fonts and bind it to `--font-base`. Headings: heavier weights, tighter letter-spacing; body: 400/500.
* Icons: **Google Material Symbols** only (Rounded style recommended).
* **Exception clause:** The source specification's "vector icons" requirement is fulfilled exclusively via Google Material Symbols — raw inline SVGs and local icon files remain forbidden.

## 4. COMPONENT DESIGN SPECIFICATIONS

**4.1 Buttons** — `.btn` block with BEM modifiers; all states styled via CSS classes:
* **Default:** `display: flex; align-items: center; justify-content: center; gap: 0.5rem;` minimum touch target 44×44px. Variants: `.btn--primary` (cobalt bg / white text), `.btn--secondary` (light bg / cobalt border + text), `.btn--danger` (coral — visually distinct in both themes).
* **Hover:** brightness/shadow shift with `cursor: pointer`.
* **Focus:** distinct ring via `outline`/`box-shadow` using `--primary` for keyboard navigation.
* **Active/Pressed:** `transform: scale(0.97)`.
* **Loading (`.btn--loading`):** disables interactions, prevents double-clicks, renders a CSS spinner or animated Material Symbol without distorting button dimensions.
* **Disabled:** `opacity: 0.5`, greyscale, `cursor: not-allowed`.
* **Success/Error:** temporary feedback styles driven by `--text-success`/`--text-error`, always paired with an icon or text — never color alone.

**4.2 Cards** — `.card` block (`.card--feature`, `.card--pricing`, `.card--testimonial`, `.card--highlight`):
* **Default:** flexible flexbox layout, `--bg-secondary`/`--bg-primary` surfaces, subtle borders + `--shadow-sm`, radii via tokens.
* **Hover:** `transform: translateY(-2px)` + shadow shift; feature cards additionally swap their tile pattern/color via `.pattern-rotate-hover`.
* **Focus-within:** border highlight when a child link/button receives focus.
* **Skeleton (`.card--skeleton`):** shimmer animation defined in CSS, no layout jump.
* **Empty state:** Google Icon + clear guidance text fallback.

**4.3 Forms & Inputs** — `.input-group` (used for the footer newsletter signup):
* **Structure:** flex container wrapping a label, input field, and dedicated error feedback container.
* **States:** empty, focused (outline ring), filled, valid (success border + icon), invalid (error border, error text, error icon), disabled, read-only.
* Errors announced via `aria-live="polite"`; never communicated by color alone.

**4.4 FAQ Accordion (disclosure widget)**
* Use semantic `<details>`/`<summary>` or a button + `aria-expanded` pattern; chevron Material icon rotates on open; smooth CSS height transition; fully keyboard operable.

**4.5 Modal / Popup (only if one is used)**
* If any popup is added (e.g., plan comparison): centered flex container (`align-items: center`), backdrop overlay, Material Icon close button, keyboard focus trapping, close via `Esc` or overlay click, opening/closing animated via CSS transitions, with loading/success/error states.

## 5. SECTION-BY-SECTION BUILD SPEC

Write real, polished English copy throughout — cultural & heritage tone: Brazilian modernist tile heritage meets collaborative digital art. No lorem ipsum.

**5.1 Header (global chrome):** sticky; flex row with a geometric CSS logo mark + wordmark; anchor nav (Features, How It Works, Testimonials, Pricing, FAQ); theme toggle (§3.3); accessible mobile menu (hamburger with `aria-expanded`, nav collapses to a column). Subtle shadow appears on scroll.

**5.2 Hero:** two-part flex layout (copy + visual), collapsing to a column on mobile. Headline + subheadline about composing collaborative azulejo art; primary CTA "Start Creating" + secondary CTA "Explore the Gallery". Visual: an `.azulejo-grid` of `.geometric-module` tiles (CSS-gradient patterns in cobalt, yellow, green, coral) that assemble with a staggered entrance animation; each tile carries `.pattern-rotate-hover` (rotates and swaps pattern/color on hover). Optional stats strip (artists, tiles composed, exhibitions).

**5.3 Features (3 cards):** `.azulejo-grid`, 3 columns → 1 column on mobile. Each card: Material icon inside a geometric tile badge, title, description. Suggested topics: Modular Tile Canvas; Real-Time Collaboration; Living Heritage Pattern Library. Hover: pattern/color change + lift; focus-within highlight.

**5.4 How It Works (3 steps):** three numbered geometric modules (01/02/03) with connecting visual rhythm; steps: Choose Your Grid → Compose & Collaborate → Publish & Exhibit. Each step: Material icon, title, description. Staggered "assembly" reveal on scroll — JS only toggles a class via `IntersectionObserver`; CSS handles the animation.

**5.5 Testimonials:** 3 quote cards. Geometric initial avatars (CSS tiles with initials, alternating accent colors — no photo assets). Semantic `figure`/`blockquote`/`figcaption`: quote, name, role (e.g., digital artist, museum curator, art educator).

**5.6 Pricing (3 tiers):** Artist (Free), Collective (mid tier — `.card--highlight` with "Most Popular" badge, accent border, slight elevation), Institution (pro). Each tier: name, monthly price + billing note, feature list with Material "check" icons, CTA button (primary on the highlighted tier, secondary on the others). Equal heights via flex; column stack on mobile.

**5.7 FAQ:** 5–6 real Q&As (collaboration, licensing, heritage patterns, exporting artwork, teams/institutions). Accordion per §4.4.

**5.8 Final CTA:** full-bleed cobalt band with a subtle CSS azulejo pattern overlay and slowly rotating decorative `.geometric-module` elements; headline + a single high-contrast CTA (light text/button on dark cobalt — contrast pairing enforced).

**5.9 Footer:** multi-column layout: brand + tagline; secondary link groups (Platform, Company, Resources, Legal — e.g., About, Gallery, Pattern Library, Licensing, Press, Privacy, Terms); newsletter `.input-group` with validation and a submit button showing loading/success/error states; social links as Material Symbols with `aria-label`; copyright line with the current year.

## 6. CORE UX & MICRO-INTERACTION RULES

* **Responsive by default:** fluid sizing and responsive breakpoints without horizontal overflow; touch targets ≥ 44px.
* **Smooth animations:** `transition: var(--transition-normal)` on all state changes; honor `prefers-reduced-motion` (disable rotation/assembly animations; keep instant state changes).
* **Accessibility (a11y):** WCAG AA contrast in both light and dark modes; semantic HTML5 (`header`, `nav`, `main`, `section`, `footer`); correct ARIA roles/labels on custom widgets; logical DOM/focus order; full keyboard operability; `aria-live` regions for dynamic feedback (form errors, loading states); never rely solely on color to communicate state.
* **Mandatory visual feedback:** every click, hover, and submission triggers a visible state change.
* **Destructive actions:** `.btn--danger` must be visually distinct in both themes.

## 7. DELIVERABLE & OUTPUT FORMAT

**7.1 File Structure:** separate `index.html`, `style.css`, and `script.js`. No inline `<style>` blocks; no inline `<script>` blocks beyond a single deferred entry-point reference.

**7.2 Naming Convention:** BEM exclusively (`.btn--primary`, `.card--feature`, `.azulejo-grid__tile`, …). The spec-provided classes `.azulejo-grid`, `.geometric-module`, and `.pattern-rotate-hover` are canonical BEM blocks/modifiers. Never mix conventions.

**7.3 Content:** real English copy everywhere; placeholders are permitted only where content was genuinely left unspecified.

**7.4 Output:** complete, runnable code delivered in a single response — first attempt, no TODOs, no truncation.
