# Porto Rocha Design System

## Overview

Porto Rocha describes itself as: “PORTO ROCHA is a global strategy and design agency with offices in New York and London. We help brands navigate complex challenges through work that is strategically rigorous, emotionally resonant, and beautifully design” The interface is light, built on **White (#FFFFFF)** with **Near Black (#000000)** text and almost no color: actions are carried by contrast, not hue.

Type is set in **sf-pro-display** and **sf-pro-text**. Headlines run large; body text is 14px. The surface language is flat. Corners are mostly 8px.

Measured from [portorocha.com](https://www.portorocha.com/) on November 4, 2026 at 1440×900 and 390×844 from 407 rendered elements. Values are computed styles from the live page, not the original source files.

## Colors

The palette has 6 roles.

- **White (#FFFFFF):** Page background, seen 1 time. Token `background`, CSS `--color-black`.
- **Near Black (#000000):** Primary text and headings, seen 101 times. Token `on-surface`, CSS `--color-white`.
- **Snow (#F5F5F5):** Raised areas one step from the page, seen 7 times. Token `surface-container-low`.
- **Near Black 4% (#0000000A):** Translucent fill for cards and controls, seen 99 times. Token `overlay`, CSS `--color-gray10`.
- **Near Black (#000000):** Primary actions (the main text color; the palette is monochrome), seen 121 times. Token `primary`, CSS `--color-white`.
- **White (#FFFFFF):** Text and icons on primary. Token `on-primary`.

## Typography

**sf-pro-display** and **sf-pro-text** share the interface. Fallback stack: `sf-pro-display, sans-serif`.

- **headline-display:** sf-pro-display 23px at weight 400, line height 1.17, tracking 0.02em (13.5px on mobile). Page title (h1).
- **body-md:** sf-pro-text 14px at weight 400, line height 1.25. Body text.

## Layout

Spacing follows a 8px grid: 98% of measured gaps and paddings are multiples of 8px.

- **Scale:** sm 8px, md 16px, lg 20px.
- **Gaps:** 12px is the most common gap in flex and grid layouts.
- **Breakpoints:** 656px, 657px, 768px, 896px, 897px, 912px, 913px, 1024px, 1025px, 1280px.

## Elevation & Depth

The design is flat: no shadows were measured. Hierarchy comes from tonal surface steps (#F5F5F5).

## Shapes

Most elements use 8px corners. Measured radii, most used first:

- **sm (8px):** 380 elements.
- **md (10px):** 52 elements.

## Components

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

- **button-ghost (“Show all projects”):** #0000000A fill, #000000 text, 14px/400, 40px radius, padding 0px 16px.
- **card:** #F5F5F5 fill, #000000 text, 14px/400, 10px radius, padding 16px.

## Do's and Don'ts

- Do use #FFFFFF for the page and lift surfaces in small steps: #F5F5F5.
- Do let contrast carry emphasis; primary actions use #000000 on #FFFFFF.
- Do keep spacing on the 8px grid.
- Do use 8px corners on most elements; larger surfaces also use 10px.
- Don't add drop shadows for depth; use tonal surfaces.
- Don't introduce new font families beyond sf-pro-display and sf-pro-text.
- Don't add saturated accent colors; the measured palette is almost entirely neutral.
- Don't make interface transitions slower than 0.5s.

## Motion

Interface transitions are quick: 0.5s.

- **Easing:** `ease`.
