# Stellar Management Design System

## Overview

Stellar Management describes itself as: “Stellar is a leading New York real estate developer and manager providing a wide range of apartments and commercial properties. Browse no fee rentals in Manhattan, Brooklyn, and Queens.” The interface is light, built on **White (#FFFFFF)** with **Charcoal (#181513)** text and almost no color: actions are carried by contrast, not hue.

Type is set in **General Sans Variable**. Headlines run large with tight negative tracking; body text is 16px. The surface language is flat. Corners are mostly 10.8px.

Measured from [stellarmanagement.com](https://www.stellarmanagement.com/) on November 6, 2026 at 1440×900 and 390×844 from 265 rendered elements. Values are computed styles from the live page, not the original source files.

## Colors

The palette has 10 roles.

- **White (#FFFFFF):** Page background, seen 8 times. Token `background`, CSS `--white`.
- **Charcoal (#181513):** Primary text and headings, seen 19 times. Token `on-surface`, CSS `--black`.
- **Near Black (#000000):** Headings and emphasis, seen 7 times. Token `on-surface-strong`.
- **Slate (#727272):** Secondary text, seen 7 times. Token `on-surface-variant`, CSS `--grey-dark`.
- **Silver (#CDCDCD):** Raised areas one step from the page, seen 24 times. Token `surface-container-low`, CSS `--grey`.
- **Near Black 60% (#00000099):** Translucent fill for cards and controls, seen 4 times. Token `overlay`.
- **Silver (#CDCDCD):** Borders and dividers, seen 9 times. Token `outline`, CSS `--grey`.
- **Charcoal (#181513):** Primary actions (the main text color; the palette is monochrome), seen 34 times. Token `primary`, CSS `--black`.
- **White (#FFFFFF):** Text and icons on primary. Token `on-primary`.
- **Deep Blue (#06184F):** Accent in text, fills and borders, seen 3 times. Token `secondary`.

## Typography

**General Sans Variable** carries the whole interface. Fallback stack: `General Sans Variable, Arial, sans-serif`. Other loaded fonts: Playfair Display.

- **headline-display:** General Sans Variable 81px at weight 500, line height 0.9, tracking -0.04em (44px on mobile). Page title (h1).
- **headline-lg:** General Sans Variable 54px at weight 500, line height 1.05, tracking -0.03em (32px on mobile). Section headings (h2).
- **headline-md:** General Sans Variable 29px at weight 500, line height 1.25, tracking -0.03em. Sub-section headings.
- **headline-sm:** General Sans Variable 21.5px at weight 500, line height 1.25, tracking -0.01em (20px on mobile). Card and feature titles.
- **body-md:** General Sans Variable 16px at weight 500, line height 1.5. Body text.
- **label-lg:** General Sans Variable 14.5px at weight 500, line height 1.5. Large buttons and tabs.
- **label-md:** General Sans Variable 12.5px at weight 500, line height 1.5. Buttons, navigation and labels.
- **label-sm:** General Sans Variable 9px at weight 500. Small labels and badges.

## Layout

Spacing does not follow a strict grid: 30% of measured values are multiples of 4px, so match the measured steps rather than rounding to a grid.

- **Scale:** xs 3.6px, sm 7.2px, md 12px, lg 24px, xl 36px.
- **Sections:** 225px vertical padding between major sections.
- **Gaps:** 18px is the most common gap in flex and grid layouts.
- **Page margin:** 36px on each side of full-width sections.
- **Breakpoints:** 360px, 480px, 560px, 650px, 651px, 767px, 967px, 968px, 1024px, 1200px, 1920px, 2440px.

## Elevation & Depth

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

## Shapes

Most elements use 10.8px corners. Measured radii, most used first:

- **md (10.8px):** 14 elements.

## Components

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

- **button-ghost (“Company”):** transparent fill, #181513 text, 14.4px/500, padding 0px.
- **card:** #00000099 fill, #FFFFFF text, 9px/500, padding 18px.
- **link:** transparent fill, #727272 text, padding 0px.

## Do's and Don'ts

- Do use #FFFFFF for the page and lift surfaces in small steps: #CDCDCD.
- Do keep text in 3 levels: #181513, #000000, #727272.
- Do let contrast carry emphasis; primary actions use #181513 on #FFFFFF.
- Do set headlines in General Sans Variable with tight tracking (-0.04em).
- Do reuse the measured spacing steps (7.2px, 12px, 24px).
- Do use 10.8px corners on most elements.
- Don't add drop shadows for depth; use tonal surfaces.
- Don't introduce new font families beyond General Sans Variable.
- 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: 0.42s, 0.5s. Longer ambient animations run 0.62s, 1.32s.

- **Easing:** `cubic-bezier(0.28, 0.11, 0.32, 1)`, `ease`.
