## 1. STRICT RULES & ARCHITECTURE

**1.1 — CSS-First Architecture & Zero Inline CSS**
* All styling lives exclusively in `style.css`. **Forbidden:** `style="..."` attributes, `<style>` blocks in HTML, and presentational HTML attributes.
* Target every design property, layout rule, and state via class or ID selectors only.
* Keep HTML semantic, clean, and style-agnostic — changing the site's look must never require markup changes.
* The only permitted non-HTML payloads in `index.html` are Google Fonts/Icons `<link>` tags and one single deferred `<script src="script.js" defer>` entry point.

**1.2 — CSS Variables & Theme Tokens**
Store every visual token in `:root`; override per-theme in `.dark`. No raw hex values may appear outside the token definitions. Light Mode is the default:

| Token | Light (default) | Dark (`.dark`) |
|---|---|---|
| `--bg-primary` | `#F7F3EC` | `#1C1A16` |
| `--bg-secondary` | `#EFE9DD` | `#26231D` |
| `--bg-elevated` | `#FEFEFE` | `#2B2821` |
| `--text-primary` | `#1C1A16` | `#F7F3EC` |
| `--text-secondary` | `#4A463E` | `#B5AE9F` |
| `--primary` | `#C4551B` | `#E8732F` |
| `--primary-hover` | `#A94615` | `#F08A4B` |
| `--on-primary` | `#FEFEFE` | `#1C1A16` |
| `--secondary` | `#4A463E` | `#B5AE9F` |
| `--text-muted` | `#8A8478` | `#8A8478` |
| `--text-success` / `--border-success` | `#2F6B3F` | `#8FCE9A` |
| `--text-error` / `--border-error` | `#B3261E` | `#F0A49B` |
| `--border-default` | `rgba(28,26,22,0.16)` | `rgba(247,243,236,0.18)` |
| `--gradient-accent` | `linear-gradient(135deg, #C4551B, #8A4630)` | `linear-gradient(135deg, #E8732F, #8A8478)` |
| `--blend-accent` | `multiply` | `screen` |
| `--grain-opacity` | `0.5` | `0.35` |

* Additional tokens: `--radius-sm: 2px`, `--radius-md: 4px`, `--radius-lg: 8px`; `--shadow-sm: 0 1px 2px rgba(28,26,22,0.08)`, `--shadow-md: 0 12px 32px rgba(28,26,22,0.14)`; `--spacing-gap: 1.5rem`, `--spacing-section: clamp(4rem, 10vw, 8rem)`; `--transition-fast: 150ms`, `--transition-normal: 300ms`, `--ease-standard: cubic-bezier(0.22, 1, 0.36, 1)`; `--z-dropdown: 40`, `--z-modal: 60`, `--z-toast: 80`.
* Fonts: `--font-display: 'Fraunces', Georgia, serif`; `--font-base: 'Inter', sans-serif`; `--font-mono: 'IBM Plex Mono', monospace`.
* **Contrast pairing is mandatory in both themes:** every light background token pairs with dark text tokens and every dark background token pairs with light text tokens. `--text-muted` (`#8A8478`) fails body-text AA on both backgrounds — use it only for text ≥24px, ≥18.66px bold, or decorative meta. Never use `#ffffff`; near-white surfaces must use `#FEFEFE`.

**1.3 — Mandatory Dark Mode**
* Define dark tokens under **both** `@media (prefers-color-scheme: dark)` and a `.dark` class on `<html>` (class wins via source order). Also set the `color-scheme` property per theme so native widgets follow.
* Theme choice persists in `localStorage` under `"meridian-theme"`; on first visit fall back to `prefers-color-scheme`. The header must contain a visible toggle button (Material Symbols `light_mode`/`dark_mode` swap) with correct `aria-pressed` and `aria-label="Toggle dark mode"` state.
* **Exception clause:** the style spec marks Light Mode as the canonical look — art-direct Light Mode first and most richly, but Dark Mode must still be a complete, deliberate implementation (adjusted grain opacity, `--blend-accent: screen`, warmer shadows), never a bare inversion.

**1.4 — CSS Grid & Flexbox Layout (Mobile-First)**
* The theme mandates **CSS Grid** for all macro layouts (12-column page grid, feature/pricing/testimonial grids); **Flexbox** for all component internals.
* Every flex container must default to `align-items: center` unless a justified exception exists (explicitly allowed exceptions: text stacks inside cards and FAQ answer panels use `align-items: flex-start` for reading comfort — document each in a CSS comment).
* Mobile-first: single column by default, promoting to multi-column at `min-width: 640/768/1024/1280`. Fluid `clamp()` type scale. **Zero horizontal scrolling at any viewport width.**

**1.5 — Tailwind CSS Integration**
* Use Tailwind CSS utilities for layout scaffolding (grid, spacing, responsive classes). All brand styling — colors, gradients, blends, grain, states, animations — must be custom CSS in `style.css` organized with `@layer` (tokens → base → components → utilities), using BEM class names (`.btn`, `.card`, `.input-group`, `.accordion__item`, `--modifier` variants) bound to the CSS variables. No arbitrary hex values in utilities.

**1.6 — Typography & Icons (Google Fonts Mandatory)**
* Include Google Fonts `<link>` tags (with `preconnect` and `display=swap`): **Fraunces** (display, optical sizing + italic), **Inter** (body/UI), **IBM Plex Mono** (eyebrows, metadata, buttons, prices).
* Icons: **Google Material Symbols (Outlined)** via Google Fonts. **Explicitly forbidden:** raw inline SVGs, local icon files, and emoji-as-icons. Decorative icons get `aria-hidden="true"`.

## 2. COMPONENT DESIGN SPECIFICATIONS

**2.1 — Buttons (`.btn`, `.btn--primary`, `.btn--ghost`)**
* **Default:** `display: flex; align-items: center; justify-content: center; gap: 0.5rem;` minimum touch target 44×44px; mono uppercase label, `letter-spacing: 0.08em`; `.btn--primary` fills `--primary` with `--on-primary` text; `.btn--ghost` uses `--border-default` border.
* **Hover:** brightness/elevation shift (`--primary-hover` fill or `--shadow-sm` for ghost) + `cursor: pointer`.
* **Focus:** distinct visible ring — `outline: 2px solid var(--primary); outline-offset: 2px` — never removed.
* **Active:** `transform: scale(0.97)`.
* **Loading (`.is-loading`):** sets `pointer-events: none`, blocks double-clicks, swaps label for the `progress_activity` icon spun by a CSS `rotate` keyframe, and **preserves the button's exact dimensions** (no layout shift).
* **Disabled:** `opacity: 0.5`, `filter: grayscale(1)`, `cursor: not-allowed`.
* **Success/Error (`.btn--success`, `.btn--error`):** temporary feedback states driven by `--text-success`/`--text-error` with `check`/`error` icons, auto-reverting after ~2.5s.

**2.2 — Cards (`.card`, `.card--featured`)**
* **Default:** flexible grid/flex layout, `--bg-elevated` surface, `1px solid var(--border-default)`, `--radius-md`, `--shadow-sm`.
* **Hover:** `transform: translateY(-2px)` + `--shadow-md` + border color shifts toward `--primary`.
* **Focus-within:** border highlights `--primary` when an inner link/button is focused.
* **Loading (Skeleton):** define a reusable `.skeleton` class with a shimmer keyframe animation (gradient sweep) and fixed aspect ratio so layout never jumps — include it in `style.css` even if static content doesn't render it.
* **Featured (pricing):** `1.5px solid var(--primary)` border, `--shadow-md`, subtle desktop scale-up, mono badge "MOST READ" on `--primary`.

**2.3 — Form & Input Group (`.input-group` — newsletter signup)**
* **Structure:** flex container wrapping `<label>`, `<input type="email">`, and a dedicated error-feedback element with `aria-live="polite"`.
* **States:** Empty (`:placeholder-shown`), Focused (3px ring via `color-mix(in srgb, var(--primary) 25%, transparent)`), Filled, Valid (`--border-success` + `check` icon), Invalid (`--border-error`, `--text-error` message, `error` icon — never color alone), Disabled, Read-only.
* **Behavior:** JS validation with an email pattern; on submit the button enters `.is-loading` for ~900ms, then inline success message replaces the form copy in the live region. Invalid submissions focus the input and render a text message.

**2.4 — FAQ Accordion (`.accordion`)**
* **States:** Closed → Opening → Open → Closing, animated with a CSS grid-rows transition (`grid-template-rows: 0fr → 1fr`, `var(--transition-normal)`).
* **Accessibility:** each question is a `<button class="accordion__trigger">` with `aria-expanded`, `aria-controls`; panel has `role="region"` + `aria-labelledby`; `expand_more` icon rotates 180° when open; triggers show hover color shift and visible focus rings; fully keyboard operable.
* No modals/popups are requested — do not build any.

---

## 3. CORE UX & MICRO-INTERACTION RULES

* **Responsive by default:** fluid `clamp()` sizing, Tailwind breakpoints, absolutely no horizontal overflow.
* **Smooth animations:** every state change uses `transition: var(--transition-fast|normal) var(--ease-standard)`. Required keyframes: orb drift, grain jitter (optional, ≤1px), ticker marquee, skeleton shimmer, spinner rotate, reveal fade-up, accordion open. All are disabled under `prefers-reduced-motion: reduce` (instant opacity only, marquee and orbs frozen).
* **Accessibility:** skip link "Skip to content"; semantic landmarks (`header`, `nav`, `main`, `section[aria-labelledby]`, `footer`); exactly one `<h1>`; logical heading order; full keyboard operability; visible `:focus-visible` rings everywhere; AA contrast (4.5:1) in **both** themes; state is never communicated by color alone — always pair with icon and/or text; `aria-live` regions for form feedback.
* **Mandatory visual feedback:** every click, hover, focus, and submission triggers a visible state change.
* **Destructive actions:** none exist on this page, but if any were added, they must be visually distinct in both themes via a `.btn--danger` class.

## 4. PAGE BLUEPRINT — SECTION-BY-SECTION ART DIRECTION

**Global effects (defined once, token-driven):**
* **Gradient orbs:** `aria-hidden` decorative panels using `--gradient-accent` with `filter: blur(70px)` and a slow 18s drift keyframe; `mix-blend-mode: var(--blend-accent)` so light mode multiplies and dark mode screens.
* **Grain:** `body::before` fixed full-viewport overlay, pure CSS (layered `radial-gradient(rgba(28,26,22,0.4) 0.5px, transparent 0.5px)` at 3px/5px repeats), `opacity: var(--grain-opacity)`, `mix-blend-mode: overlay`, `pointer-events: none`. No images, no data-URIs, no SVG.
* **Reveal-on-scroll:** `.reveal` elements fade/translate up when an IntersectionObserver adds `.is-visible`.
* All visuals are pure CSS art (gradient panels, oversized numerals, grain) — no raster `<img>` assets. Use `aspect-ratio: 3/4` for cover-style panels.

**Sections (in order, all copy authored by you in English — original editorial voice, never lorem ipsum):**
1. **Header (sticky):** frosted paper bar (`--bg-primary` at 80% alpha + `backdrop-filter: blur(12px)`, `z-index: var(--z-dropdown)`); "MERIDIAN" wordmark in Fraunces + mono "ISSUE 07" meta; anchor nav (Features, Method, Pricing, FAQ); theme toggle; "Subscribe" primary button; mobile `menu` icon button opening an accessible disclosure panel (aria-expanded, Esc closes, focus returns).
2. **Hero:** 12-col grid — text column (mono eyebrow "ISSUE NO. 07", huge Fraunces headline with one italic accent word in `--primary`, lede in `--text-secondary`, primary CTA + ghost CTA, mono meta row "184 PAGES · 12 ESSAYS · 4 INTERVIEWS") beside a CSS-art cover panel: gradient panel, blurred orb, oversized italic "07" numeral with `mix-blend-mode: var(--blend-accent)`, grain. Staggered load-in animation; animated "SCROLL" cue with `south` icon.
3. **Ticker:** full-width mono marquee strip ("ESSAYS — FIELD NOTES — INTERVIEWS — DISPATCHES — THE ARCHIVE"), seamless loop via a duplicated `aria-hidden` copy, pauses on hover, frozen by reduced-motion.
4. **Features — "Inside the Issue":** section header pattern (mono eyebrow + Fraunces `H2` + hairline rule) used consistently; 3 `.card`s (icon in a tinted square, mono kicker, Fraunces `H3`, body copy, "Read more" link with `arrow_forward` translating on hover) in a 1→3 column grid with `var(--spacing-gap)`.
5. **How It Works — "The Meridian Method":** 3 numbered steps (oversized Fraunces italic "01/02/03" in `--text-muted`, filling `--primary` on hover), top rule line, step titles + descriptions, mobile-first stacking.
6. **Testimonials — "Field Notes from Readers":** 3 quote cards (large Fraunces italic quote, decorative `format_quote` icon, mono attribution "— Name, Role"), middle card offset `translateY(2rem)` on desktop for editorial rhythm, hover lift per 2.2.
7. **Pricing:** 3 `.card--pricing` tiers — Single Issue $14 (one-time), Annual $72/yr (featured, "MOST READ" badge, "$6 an issue" note), Patron $180/yr; each with Fraunces price, check-icon feature list, CTA (featured fills primary, others ghost); mono footnote "Cancel anytime."
8. **FAQ:** 5 real questions (digital/print access, frequency, cancellation, gifting, archive access) using the accordion from 2.4.
9. **Final CTA (#subscribe):** full-bleed panel with gradient orbs + grain, Fraunces headline, the newsletter `.input-group` + submit button implementing every state in 2.1/2.3, mono consent microcopy, success feedback in an `aria-live` region.
10. **Footer:** `--bg-secondary`; brand column (wordmark, blurb, icon-link buttons `mail`/`rss_feed`/`public` with `aria-label`s); secondary link columns "Magazine" (Archive, Masthead, Stockists), "Company" (About, Contact, Careers), "Legal" (Privacy, Terms, Cookies, Accessibility) with slide-underline hover; bottom bar with JS-injected year and "TOP" link with `north` icon.

## 5. DELIVERABLE & OUTPUT FORMAT

* **Files:** `index.html`, `style.css`, `script.js` — separate, complete, in one response. No inline `<script>` beyond the single deferred `script.js` reference.
* **Naming:** strict BEM throughout (`block__element--modifier`); never mix conventions. Core classes: `.btn--primary`, `.btn--ghost`, `.card`, `.card--featured`, `.input-group`, `.accordion__trigger`, `.hero__cover`, `.ticker__track`, `.reveal`, `.skeleton`.
* **script.js must contain only:** theme init/persist/toggle (first statements, applying `.dark` from `localStorage` → `prefers-color-scheme` fallback); mobile menu; accordion toggling; newsletter validation + loading/success/error flow; IntersectionObserver reveals; smooth anchor scrolling; footer year. No other JS. No console errors.
* **No unrequested placeholders:** all user-facing copy is original English editorial copy for the MERIDIAN journal; `href="#"` is acceptable only for footer links with no real destination.
* **Verification before submitting:** both themes toggle correctly and persist; all states in Section 2 render correctly; keyboard-only navigation works end to end; no horizontal scroll from 320px up.
