## 1. STRICT RULES & ARCHITECTURE

### 1.1 CSS-First Architecture & Zero Inline CSS
- **No Inline CSS:** The `style="..."` attribute is **forbidden anywhere in the HTML**. Zero exceptions.
- **Class/ID Selectors Only:** Every visual property, layout rule, state, animation, and effect must be targeted via class or ID selectors in `style.css`.
- **Minimal HTML Modifications:** HTML must remain clean, semantic (landmarks, headings, buttons, lists), and style-agnostic. Re-theming the page must be achievable by editing `style.css` alone.

### 1.2 CSS Variables & Theme Tokens
Store **all** visual tokens in `:root` and redefine per theme. Use exactly these token names:

| Token | Light (default) | Dark |
|---|---|---|
| `--bg-primary` | `#e8dcc8` (warm cream — never pure white) | `#0a0705` |
| `--bg-secondary` | `#f3ead9` (use `#fefefe` only where a near-white surface is required — never `#ffffff`) | `#241a12` |
| `--text-primary` | `#241a12` | `#e8dcc8` |
| `--text-secondary` | `#5f4f3a` (darkened taupe for AA body-text contrast) | `#b5a48b` |
| `--primary` | `#ff9d42` | `#ff9d42` |
| `--primary-strong` | `#e86a2e` | `#e86a2e` |
| `--secondary` | `#a08c6e` | `#a08c6e` |
| `--text-on-primary` | `#0a0705` (dark text on amber fills for AA contrast) | `#0a0705` |
| `--text-success` / `--border-success` | `#2e6b3f` | `#7cc98f` |
| `--text-error` / `--border-error` | `#b3261e` | `#ff9d8a` |
| `--border-default` | `rgba(36,26,18,0.14)` | `rgba(232,220,200,0.16)` |
| `--glass-bg` | `rgba(254,254,254,0.42)` | `rgba(36,26,18,0.50)` |
| `--glass-bg-strong` | `rgba(254,254,254,0.60)` | `rgba(36,26,18,0.68)` |
| `--glass-border` | `rgba(255,255,255,0.55)` | `rgba(232,220,200,0.18)` |
| `--glass-blur` | `18px` | `18px` |
| `--glow-amber` | `rgba(255,157,66,0.45)` | `rgba(255,157,66,0.35)` |
| `--glow-ember` | `rgba(232,106,46,0.40)` | `rgba(232,106,46,0.45)` |

- **Shared tokens:** `--radius-sm: 10px`, `--radius-md: 18px`, `--radius-lg: 28px`, `--shadow-sm`, `--shadow-md`, `--shadow-glow` (built from `--glow-amber`), `--spacing-gap: 1.5rem`, `--transition-fast: 150ms`, `--transition-normal: 320ms`, `--ease-standard: cubic-bezier(0.4, 0, 0.2, 1)`, `--z-header: 90`, `--z-dropdown: 100`, `--z-modal: 200`, `--z-toast: 300`, `--font-display`, `--font-base`.
- **Contrast Pairing (mandatory in both themes):** every light background token pairs with dark text tokens; every dark background token pairs with light text tokens. Raw `#a08c6e` is decorative/large-display only — never body text.
- **Amber/orange tokens (`#ff9d42`, `#e86a2e`) are accent colors:** use them for fills with `--text-on-primary` text, glows, borders, and large display type — never as small-text color on cream.

### 1.3 Mandatory Dark Mode Support
- **Implementation:** Define light tokens in `:root`; provide dark overrides both under `@media (prefers-color-scheme: dark)` (applied to `:root:not(.light)`) and a `.dark` class on `<html>`. Switching themes must change variables only — **no HTML restructuring**.
- **Persistence:** Store the user's choice in `localStorage` (key: `glasshouse-theme`); apply before first paint to avoid flash; provide a visible toggle in the header with correct `aria-pressed` and `aria-label` state and Google Material Symbols `light_mode` / `dark_mode` icons.
- **Exception (per source spec):** Light mode is the **first-visit default** for this theme; the dark token set, toggle control, and persistence architecture above remain fully mandatory.

### 1.4 Flexbox Layout & Mobile-First Alignment
- Build **all** layout structures with Flexbox (`display: flex`, `flex-wrap`, `gap: var(--spacing-gap)`).
- **Default Alignment Rule:** every flex container defaults to `align-items: center` unless an exception is explicitly documented in a CSS comment (e.g., card text columns use `align-items: flex-start` for reading flow).
- **Mobile-first:** single-column stacks below 768px; rows wrap into 3-across at ≥1024px. Use `clamp()` for fluid type. **Horizontal scrolling is forbidden** — orb/effect layers must sit inside `overflow: hidden` wrappers.

### 1.5 Framework Decision: Clean Custom CSS
- **No frameworks, no Tailwind, no CDN utility classes.** Write hand-authored CSS in `style.css`, organized in commented layers: Tokens → Base/Reset → Layout → Components → Sections → Utilities. All styling flows through CSS variables and reusable component classes (`.btn`, `.card`, `.glass-panel`, `.input-group`, `.faq-item`).

### 1.6 Typography & Icons (Google Fonts Mandatory)
- **Fonts:** Load **Fraunces** (display: headlines, numerals) and **Outfit** (body/UI) via Google Fonts `<link>` with `preconnect`. Bind them to `--font-display` and `--font-base`. All text uses `--font-base`; all headings/hero use `--font-display`.
- **Icons:** Google **Material Symbols (Rounded)** via the standard `<link>` stylesheet, used with the `.material-symbols-rounded` class. **Raw inline SVGs, emoji icons, and local icon files are forbidden.** Decorative icons get `aria-hidden="true"`; meaningful icons get accessible names.

### 1.7 Glassmorphism & Effect Standards (Theme-Critical)
- **Glass surface recipe (`.glass-panel`, `.card`, header, modal):** `background: var(--glass-bg)`; `-webkit-backdrop-filter: blur(var(--glass-blur)) saturate(140%)`; `backdrop-filter: blur(var(--glass-blur)) saturate(140%)`; `border: 1px solid var(--glass-border)`; `border-radius: var(--radius-lg)`; an inset top highlight (`inset 0 1px 0 rgba(255,255,255,…)` in light mode, softened in dark).
- **Fallback:** wrap `backdrop-filter` in `@supports`; unsupported browsers get a higher-alpha solid background so text stays readable.
- **Ambient orbs:** 3+ absolutely-positioned radial-gradient circles (`#ff9d42`, `#e86a2e`, `#a08c6e`), `filter: blur(70px)`, reduced opacity, animated with an `orb-float` keyframe (18–26s, alternate, infinite). Mark `aria-hidden="true"`, `pointer-events: none`, contained to prevent overflow.
- **Glow:** `box-shadow: 0 0 40px var(--glow-amber)` on featured elements; a `pulse-glow` keyframe on the hero badge and primary CTA.
- **Neumorphism hybrid:** the theme toggle, step-number badges, and icon chips get soft dual shadows (light mode: `8px 8px 20px rgba(10,7,5,0.12), -8px -8px 20px rgba(255,255,255,0.7)`; dark mode: subtle inset equivalents) blended with the glass surface.
- **Gradient text:** hero headline accent span uses `linear-gradient(135deg, #ff9d42, #e86a2e)` with `background-clip: text` / `-webkit-text-fill-color: transparent` and a solid `--primary-strong` fallback.
- **Required keyframes:** `orb-float`, `pulse-glow`, `shimmer` (skeleton), `spin` (loading), `fade-up` (scroll reveal).

## 2. COMPONENT DESIGN SPECIFICATIONS

### 2.1 Button Component (`.btn` + modifiers `.btn--primary`, `.btn--glass`, `.btn--danger`)
- **Default:** `display: flex; align-items: center; justify-content: center; gap: 0.5rem;` minimum 44×44px touch target, `border-radius: var(--radius-md)`, `transition: var(--transition-fast)`. `.btn--primary` uses the amber→ember gradient with `color: var(--text-on-primary)`; `.btn--glass` uses the glass recipe with `--text-primary`.
- **Hover:** `filter: brightness(1.06)`, `translateY(-1px)`, glow shadow, `cursor: pointer`.
- **Focus:** distinct `:focus-visible` ring via `outline` + glow `box-shadow` using `--primary` — visible in both themes.
- **Active/Pressed:** `transform: scale(0.97)`.
- **Loading (`.is-loading`):** `aria-busy="true"`, `pointer-events: none`, spinner via Material Symbol `progress_activity` + `spin` keyframe; button dimensions must not shift (reserve a `min-width`).
- **Disabled (`[disabled]`):** `opacity: 0.5`, grayscale filter, `cursor: not-allowed`.
- **Success/Error:** `.is-success` / `.is-error` temporary feedback states (2s) using `--text-success` / `--text-error` with a check/close Material icon — never color alone.
- **Danger:** `.btn--danger` must be visually distinct in both themes (error tokens + warning icon).

### 2.2 Card Component (`.card` — used by Features, Testimonials, Pricing)
- **Default:** flexbox column layout, glass surface recipe, `--bg-secondary`/glass tokens, subtle border and `--shadow-sm` elevation.
- **Hover:** `transform: translateY(-2px)` and shadow/glow shift.
- **Focus-within:** card border highlights (`--primary`) when a child link/button receives focus.
- **Loading (Skeleton):** define `.skeleton` with the `shimmer` keyframe; apply to any dynamically injected card content to prevent layout jumps.
- **Empty State:** define a reusable pattern — 48px Material icon + short guidance text — for any region that could render without content.
- **Featured variant (`.card--featured`):** gradient border (pseudo-element), `pulse-glow` badge, stronger glow, `scale(1.03)` at ≥768px.

### 2.3 Form & Input (`.input-group` — used in the Final CTA email capture)
- **Structure:** flex column wrapping `<label>`, the input (min-height 48px), and a dedicated error feedback container with `aria-live="polite"`. (Documented alignment exception: `align-items: flex-start` for reading flow.)
- **States — all styled via classes/attributes:** empty, focused (outline ring using `--primary`), filled, valid (`--border-success` + check icon), invalid (`--border-error`, error text, error icon, `aria-invalid="true"`, `aria-describedby`), disabled, read-only.
- **Submit flow:** button enters `.is-loading` (prevent double-clicks) → inline success message renders in the `aria-live` region with a check icon. Simulated async is acceptable; the state machine is not.

### 2.4 Modal / Popup (conditional — only if "Book the Hot Shop" opens a dialog instead of scrolling)
- **States:** opening, open, loading, success/error, closing — all animated with CSS transitions (opacity + `scale(0.96→1)`).
- **UX:** fixed backdrop `rgba(10,7,5,0.55)` + `blur(8px)`; centered flex container (`align-items: center; justify-content: center`); glass panel at `--z-modal`; `role="dialog"`, `aria-modal="true"`, `aria-labelledby`; Material `close` icon button (44px); close via `Esc` and overlay click; keyboard focus trapping with focus return; body scroll lock.

### 2.5 FAQ Accordion (`.faq-item`)
- **Trigger:** a real `<button>` with `aria-expanded` and `aria-controls`; Material `expand_more` icon rotating 180° on open; hover and `:focus-visible` states.
- **Panel:** open/close animated via `grid-template-rows: 0fr → 1fr` transition (or equivalent smooth technique); one item open at a time; fully keyboard operable; instant toggle under `prefers-reduced-motion`.

## 3. PAGE SECTION REQUIREMENTS

All user-facing copy must be **original, on-theme English** for a glassblowing studio (furnace, blowpipe, gather, marver, annealer, glory hole) — **no lorem ipsum**.

- **3.1 Sticky Header:** glass bar (`--z-header`) with the GLASSHOUSE wordmark, anchor nav (Features, Process, Pricing, FAQ), and the theme toggle. Below 768px, links collapse behind a Material `menu` button (`aria-expanded`) opening a glass dropdown at `--z-dropdown`. Add a skip-to-content link.
- **3.2 Hero:** full-viewport glass panel over animated orbs; single `<h1>` in `--font-display` with a gradient-text accent; subcopy; two CTAs — `.btn--primary` "Book the Hot Shop" and `.btn--glass` "See the Process" (smooth-scroll to targets); a stats row (e.g., 2,100°F furnace, 12 master blowers, 48h annealing); a pulsing-glow badge; scroll cue.
- **3.3 Features — 3 glass cards:** e.g., "The 2,100°F Furnace", "Hands-On Master Guidance", "Annealed to Last" — each with a neumorphic icon chip (Material `local_fire_department`, `workspace_premium`, `thermostat`), title, copy; hover lift and scroll-reveal.
- **3.4 How It Works — 3 steps:** numbered `01 / 02 / 03` badges (gradient display numerals) — Gather, Shape, Anneal — connected by a pseudo-element line on desktop, stacked column on mobile.
- **3.5 Testimonials — 3 glass quote cards:** Material `format_quote` icon, quote, gradient-initial avatars (no external images), name + role, 5-star rating via Material `star` icons with an `sr-only` "Rated 5 out of 5" text (never color/icon-only meaning).
- **3.6 Pricing — 3 tiers:** "Ember Drop-In" ($75/session), "Studio Member" (featured, $190/mo, `.card--featured` + "Most Popular" badge), "Private Hot Shop" ($520/event). Feature lists with Material `check` icons; each tier has a CTA (featured = `.btn--primary`, others = `.btn--glass`).
- **3.7 FAQ:** 5–6 realistic questions (experience needed, age minimum, clothing/closed-toe natural-fiber policy, 24h annealing pickup, 48h cancellation) using the 2.5 accordion spec.
- **3.8 Final CTA:** large glowing glass panel, display headline, and the 2.3 email-capture form ("Get the studio schedule") with full state machine and `aria-live` feedback.
- **3.9 Footer:** dark surface panel — in light mode use `#241a12` background with `#e8dcc8` text (contrast pairing enforced) — containing brand blurb, **secondary link columns** (About, Classes, Gift Cards, Contact, Privacy, Terms), social links as text + generic Material Symbols (`alternate_email`, `public`, `chat_bubble` — no brand logos, no SVGs), dynamic copyright year, and a back-to-top link. All links have hover and `:focus-visible` states.

---

## 4. CORE UX & MICRO-INTERACTION RULES

- **Responsive by default:** fluid `clamp()` sizing, flexbox wrapping, breakpoints at 640/768/1024px, zero horizontal overflow, `scroll-padding-top` for the sticky header.
- **Smooth animations:** `transition: var(--transition-normal)` on all state changes; scroll-reveal via `IntersectionObserver` adding `.is-visible` to `.reveal` elements (`fade-up`); `html { scroll-behavior: smooth }`. **All motion disabled under `prefers-reduced-motion`** (orbs freeze, reveals render visible, transitions near-zero).
- **Accessibility (a11y):** AA contrast in both themes; semantic HTML5 landmarks and heading order; ARIA roles/labels on the toggle, menu, accordion, and any modal; logical focus order; full keyboard operability; `aria-live` regions for form/toast-style feedback; state never communicated by color alone.
- **Mandatory visual feedback:** every click, hover, and submission triggers a visible state change.
- **Destructive/distinct actions:** any destructive control uses `.btn--danger` and reads distinctly in light and dark themes.

## 5. DELIVERABLE & OUTPUT FORMAT

- **File structure:** three separate files — `index.html`, `style.css`, `script.js`. The only `<script>` in the HTML is a single `<script src="script.js" defer></script>`. Google Fonts and Material Symbols `<link>` tags in `<head>`. No build tools, no frameworks.
- **Naming convention:** **BEM only**, consistently — `.hero__title`, `.card--featured`, `.faq-item__panel`, `.btn--primary`. Never mix conventions.
- **JavaScript scope (script.js only):** theme toggle + `localStorage` persistence; mobile menu; FAQ accordion; IntersectionObserver reveals; smooth-scroll for anchor CTAs; email form validation + simulated submit with loading/success/error states. Nothing beyond this scope.
- **No unrequested placeholders:** write final, realistic studio copy for every section — headings, features, steps, testimonials, pricing, FAQ, footer. No lorem ipsum, no "TBD", no dead links (footer links may use `href="#top"`-style in-page anchors).
- **Single attempt:** deliver the complete, fully wired page in one response — every button state, every theme token, every animation defined and functional.
