# EternaCloud Design System

## Overview

EternaCloud describes itself as: “EternaCloud helps data center owner, provider and supplier teams execute global design standards across groups, regions and builds for critical equipment.” The interface is dark, built on **Cool Charcoal (#13101C)** with **White (#FFFFFF)** text, and **Vivid Blue (#1C4EFF)** as the main accent.

Type is set in **Mazzardh** and **Arial**. Headlines run large with tight negative tracking; body text is 14px. The surface language is flat. Corners are mostly 9.94px.

Measured from [eternacloud.com](https://www.eternacloud.com/) on November 6, 2026 at 1440×900 and 390×844 from 140 rendered elements. Values are computed styles from the live page, not the original source files.

## Colors

The palette has 11 roles, plus gradient stops #FE881B, #AC24FF, #1C4EFF, #2BA7FF.

- **Cool Charcoal (#13101C):** Page background, seen 2 times. Token `background`.
- **White (#FFFFFF):** Primary text and headings, seen 7 times. Token `on-surface`, CSS `--k-consentGate-header-background`.
- **Deep Violet (#170D27):** Raised areas one step from the page, seen 1 time. Token `surface-container-low`.
- **Deep Violet (#170F22):** Cards and panels, seen 1 time. Token `surface-container`.
- **Near Black (#000000):** Hover and pressed fills, seen 1 time. Token `surface-container-high`, CSS `--k-preference-tabs-purposes-header-link-color`.
- **Cool Charcoal 55% (#0A05148C):** Translucent fill for cards and controls, seen 4 times. Token `overlay`.
- **Near Black (#000000):** Borders and dividers, seen 2 times. Token `outline`, CSS `--k-preference-tabs-purposes-header-link-color`.
- **Vivid Blue (#1C4EFF):** Primary buttons and calls to action, seen 15 times. Token `primary`.
- **White (#FFFFFF):** Text and icons on primary. Token `on-primary`.
- **Deep Violet (#1A0B54):** Accent in the logo, seen 18 times. Token `secondary`.
- **Light Violet (#C86FFF):** Accent, seen 14 times. Token `tertiary`.

## Typography

**Mazzardh** and **Arial** share the interface. Fallback stack: `Mazzardh, Arial, sans-serif`.

- **headline-display:** Mazzardh 58px at weight 500, line height 1.1, tracking -0.03em (31px on mobile). Page title (h1).
- **headline-lg:** Mazzardh 46px at weight 500, line height 1.1, tracking -0.035em (25.5px on mobile). Section headings (h2).
- **headline-md:** Mazzardh 20px at weight 400, line height 1.25, tracking -0.03em. Sub-section headings.
- **body-md:** Mazzardh 14px at weight 400, line height 1, tracking -0.03em. Body text.
- **body-sm:** Mazzardh 12px at weight 400, line height 1.2. Secondary and small text.
- **label-md:** Arial 14px at weight 600, line height 1.5. Buttons, navigation and labels.

## Layout

Spacing does not follow a strict grid: 11% of measured values are multiples of 4px, so match the measured steps rather than rounding to a grid.

- **Scale:** xs 2.02px, sm 7.2px, md 11.52px, lg 22.03px, xl 40.03px.
- **Gaps:** 11.52px is the most common gap in flex and grid layouts.
- **Breakpoints:** 1px, 420px, 479px, 480px, 767px, 768px, 769px, 991px, 992px, 1024px, 1280px, 1440px, 1920px.

## Elevation & Depth

The design is flat: no shadows were measured. Hierarchy comes from tonal surface steps (#170D27 → #170F22 → #000000) and #000000 borders.

## Shapes

Most elements use 9.94px corners. Measured radii, most used first:

- **sm (9.94px):** 36 elements.
- **md (31.97px):** 16 elements.
- **full (9999px):** 8 elements.

## Components

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

- **button-primary (“Contact”):** #1C4EFF fill, #FFFFFF text, 20.0016px/400, 9.936px radius, padding 1px.
- **button-ghost (“Reject All”):** transparent fill, #000000 text, 14px/600, padding 0px 16px, border 1px solid #000000, shadow `rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px`.
- **card:** #0A05148C fill, #FFFFFF text, 20.0016px/400, 31.968px radius, padding 27.94px 33.98px 0px 33.98px.

## Do's and Don'ts

- Do use #13101C for the page and lift surfaces in small steps: #170D27, #170F22, #000000.
- Do reserve #1C4EFF for primary actions and key highlights.
- Do set headlines in Mazzardh with tight tracking (-0.03em).
- Do reuse the measured spacing steps (7.2px, 11.52px, 22.03px).
- Do use 9.94px corners on most elements; larger surfaces also use 31.97px.
- Don't add drop shadows for depth; use tonal surfaces.
- Don't introduce new font families beyond Mazzardh and Arial.
- Don't use #1C4EFF for large backgrounds or body text.
- Don't make interface transitions slower than 0.4s.

## Motion

Interface transitions are quick: 0.3s, 0.4s. Longer ambient animations run 1s.

- **Easing:** `ease`, `cubic-bezier(0.4, 0, 0.2, 1)`.
