# Sitepeel Design System

## Overview

Sitepeel describes itself as: “Sitepeel is a website cloner and inspector for Chrome. Copy HTML and CSS, clone pages, generate Design MD and compare responsive layouts with 13 tools.” The interface is dark, built on **Near Black (#09090B)** with **White (#FFFFFF)** text and almost no color: actions are carried by contrast, not hue.

Type is set in **Geist**. Headlines run large with tight negative tracking; body text is 14px. Depth comes from soft drop shadows. Corners are mostly 7px.

Measured from [sitepeel.dev](https://sitepeel.dev/) on October 21, 2026 at 1440×900 and 390×844 from 419 rendered elements. Values are computed styles from the live page, not the original source files.

## Colors

The palette has 15 roles, plus gradient stops #C4A5ED.

- **Near Black (#09090B):** Page background, seen 1 time. Token `background`.
- **White (#FFFFFF):** Primary text and headings, seen 165 times. Token `on-surface`.

- **Charcoal (#101014):** Raised areas one step from the page, seen 1 time. Token `surface-container-low`.
- **Charcoal (#111013):** Cards and panels, seen 3 times. Token `surface-container`.

- **Near Black 13% (#00000022):** Translucent fill for cards and controls, seen 13 times. Token `overlay`.
- **Light Violet 5% (#C4A5ED0C):** Stronger translucent fill, seen 13 times. Token `overlay-strong`.
- **White 17% (#FFFFFF2B):** Borders and dividers, seen 31 times. Token `outline`.

## Typography

**Geist** carries the whole interface. Fallback stack: `Geist, Arial, sans-serif`.

- **headline-display:** Geist 100px at weight 510, line height 1.08, tracking -0.065em (48.5px on mobile). Page title (h1).
- **headline-lg:** Geist 59px at weight 460, line height 1.09, tracking -0.05em. Section headings (h2).
- **headline-md:** Geist 53px at weight 470, line height 1.1, tracking -0.05em. Sub-section headings.

## Layout

Spacing does not follow a strict grid: 36% of measured values are multiples of 4px, so match the measured steps rather than rounding to a grid.

- **Scale:** xs 2px, sm 8px, md 10px, lg 18px, xl 48px.
- **Sections:** 88px vertical padding between major sections.
- **Gaps:** 10px is the most common gap in flex and grid layouts.
- **Container:** content is capped at 1280px.
- **Breakpoints:** 319px, 360px, 380px, 400px, 480px, 580px, 600px, 680px, 760px, 761px, 800px, 900px, 980px, 981px, 1000px, 1100px, 1180px, 1500px.

## Elevation & Depth

Raised elements use soft drop shadows. The most used recipes:

- `rgba(0, 0, 0, 0.2) 0px 2px 10px 0px`
- `rgba(179, 138, 232, 0.43) 0px 0px 12px 0px`
- `rgba(16, 11, 32, 0.125) 0px 4px 22px 0px`

## Shapes

Most elements use 7px corners. Measured radii, most used first:

- **sm (7px):** 144 elements.
- **md (9px):** 72 elements.
- **lg (12px):** 64 elements.
- **xl (16px):** 16 elements.
- **full (9999px):** 4 elements.

## Components

Measured from the rendered page. Token values reference the tokens above.

- **button-primary (“Add to Chrome Free install”):** #F4F2F6 fill, #151319 text, 13px/600, 8px radius, padding 11px 15px, border 1px solid #F4F2F6.
- **button-secondary (“Add to Chrome Free install”):** #F4F0F8 fill, #17121D text, 13px/600, 7px radius, padding 10px 14px, border 1px solid #F4F0F8.
- **button-outline (“Your account”):** #211A29 fill, #FFFFFF text, 13px/550, 8px radius, padding 8px 12px, border 1px solid #B48BDD.
- **button-outline-hover:** background #33263F, text #FFFFFF on hover.
- **link:** transparent fill, #FFFFFF text, padding 0px.

## Do's and Don'ts

- Do use #09090B for the page and lift surfaces in small steps: #101014, #111013, #121015, #161319.
- Do keep text in 2 levels: #FFFFFF, #215238.
- Do let contrast carry emphasis; primary actions use #F4F2F6 on #09090B.
- Do set headlines in Geist with tight tracking (-0.065em).
- Do reuse the measured spacing steps (8px, 10px, 18px).
- Do use 7px corners on most elements; larger surfaces also use 9px, 12px and 16px.
- Don't use #215238 for body text; it reaches 2.2:1 on #09090B. Keep it for large text or metadata.
- Don't introduce new font families beyond Geist.
- Don't add saturated accent colors; the measured palette is almost entirely neutral.
- Don't make interface transitions slower than 0.25s.

## Motion

Interface transitions are quick: 0.18s, 0.2s, 0.25s, 0.15s.

- **Easing:** `ease`.
- **Reduced motion:** the page responds to `prefers-reduced-motion`.
