## Overview

A stark, gallery-inspired luxury e-commerce platform that prioritizes oversized editorial photography and generous whitespace.

*A high-fashion gallery where the product is the sculpture.*

## Colors

Strict monochrome palette relying entirely on large-scale photography for visual interest and emotion.

- **Background (`#FFFFFF`)** — uses `bg` token
- **Primary text (`#111111`)** — uses `ink` token
- **Secondary text (`#343434`)** — uses `ink-soft` token
- **Muted (`#858585`)** — uses `muted` token
- **Borders (`rgba(229,231,235,1.0)`)** — uses `line` token

## Typography

- **Display:** transitional-serif
- **Body:** humanist-sans

- Maintain strict hierarchy between the bold serif logotype and the clean sans-serif UI elements.
- Keep line heights tight for large display text to maintain a compact, editorial feel.
- Use generous tracking and uppercase styling sparingly for utility labels like 'TOP 20 BESTSELLER'.

## Layout

A top-heavy visual layout starting with a full-width editorial hero, followed by clean, left-aligned product grids and generous vertical padding.

*Rhythm:* Flexible and breathing; generous whitespace is used to elevate the product photography and maintain a premium, uncluttered feel.

- `lg`: 25px
- `pill`: 9999px

## Components

- **button:** High-contrast primary buttons with solid black backgrounds and white text; pill-shaped variants for secondary actions.
- **card:** Minimalist product cards with large imagery, clean sans-serif typography, and minimal borders.
- **chip:** Pill-shaped elements, often used for quick navigation or filtering.
- **input:** Clean text inputs with subtle bottom borders or enclosed in soft rounded containers.
- **hero:** Full-bleed, high-resolution photographic canvases that prioritize visual impact over text.

## Do's and Don'ts

**Don't:**
- don't use bright neon colors — the palette is strictly monochrome (#111111, #FFFFFF, #858585).
- don't clutter the UI with dense text blocks — the layout prioritizes breathing room and white space.
- don't use playful or rounded sans-serif fonts — the typography is a refined transitional serif paired with a clean humanist sans.
- don't add heavy drop shadows or 3D effects — surfaces are mostly flat with very subtle, soft shadows.
- don't use a vibrant or high-chroma accent color — the site relies entirely on black, white, and photography for color.
- don't use complex grid layouts with many columns — the structure is clean, mostly single-column or simple 12-column grids.

The palette is strictly monochrome, using deep black (#111111) for text, white (#FFFFFF) for backgrounds, and light gray (#F3F4F6) for subtle surfaces. Typography pairs a bold transitional serif for the logotype with a clean humanist sans-serif for the UI. The layout is spacious, prioritizing large-scale photography and generous whitespace over dense information. Critical donts: never use bright or saturated accent colors; avoid cluttered, dense text layouts; do not use heavy or complex drop shadows. The site feels like a curated digital gallery, using restraint and negative space to elevate the product imagery.
