# DeployOnce Design System

## Overview

DeployOnce describes itself as: “DeployOnce builds and deploys applications from GitHub repositories. Detect your stack, review build settings, and manage Docker-based deployments, logs, and database options in one place.” The interface is dark, built on **Cool Charcoal (#0A0D14)** with **Snow (#F8FAFC)** text, and **Deep Cyan (#0A313D)** as the main accent.

Type is set in **Space Grotesk** and **Inter**, with **ui-monospace** for code. Headlines run large with tight negative tracking; body text is 14px. Depth comes from soft drop shadows. Controls are pill-shaped.

Measured from [app.deployonce.app](https://app.deployonce.app/) on November 5, 2026 at 1440×900 and 390×844 from 328 rendered elements. Values are computed styles from the live page, not the original source files.

## Colors

The palette has 14 roles, plus gradient stops #00E1FF, #41DCFB.

- **Cool Charcoal (#0A0D14):** Page background, seen 4 times. Token `background`.
- **Snow (#F8FAFC):** Primary text and headings, seen 63 times. Token `on-surface`.
- **Mist (#E1E3E5):** Secondary text, seen 8 times. Token `on-surface-variant`.
- **Cool Silver (#BCBFC2):** Muted text and metadata, seen 6 times. Token `on-surface-muted`.
- **Blue (#909EB2):** Subtle text and placeholders, seen 41 times. Token `on-surface-subtle`.
- **Cool Charcoal (#0E141B):** Raised areas one step from the page, seen 1 time. Token `surface-container-low`.
- **Cool Charcoal 60% (#14192499):** Translucent fill for cards and controls, seen 30 times. Token `overlay`.
- **Cool Charcoal 40% (#14192466):** Stronger translucent fill, seen 8 times. Token `overlay-strong`.
- **Deep Blue (#1F293D):** Borders and dividers, seen 53 times. Token `outline`.
- **Snow 13% (#F8FAFC21):** Secondary dividers, seen 5 times. Token `outline-variant`.
- **Deep Cyan (#0A313D):** Brand color in logos and imagery. Token `primary`.
- **White (#FFFFFF):** Text and icons on primary. Token `on-primary`.
- **Vivid Cyan (#00E1FF):** Accent in text, fills and borders, seen 51 times. Token `secondary`.
- **Teal (#10B77F):** Success and positive states, seen 4 times. Token `success`.

## Typography

**Space Grotesk**, **Inter** and **ui-monospace** (monospace) share the interface. Fallback stack: `Space Grotesk, Space Grotesk Fallback, Space Grotesk, ui-sans-serif`.

- **headline-display:** Space Grotesk 153.5px at weight 700, line height 1.08, tracking -0.03em (46px on mobile). Page title (h1).
- **headline-lg:** Space Grotesk 95px at weight 700, line height 1.08, tracking -0.06em. Section headings (h2).
- **headline-md:** Space Grotesk 57.5px at weight 700, line height 1.05, tracking -0.03em (33.5px on mobile). Sub-section headings.
- **headline-sm:** Space Grotesk 20px at weight 600, line height 1.4, tracking -0.03em. Card and feature titles.
- **body-md:** Inter 14px at weight 400, line height 1.43. Body text.
- **body-lg:** Inter 16px at weight 400, line height 1.5. Lead paragraphs.
- **label-md:** Inter 14px at weight 500, line height 1.43. Buttons, navigation and labels.
- **code:** ui-monospace 11px at weight 600, line height 1.5, tracking 0.19em, uppercase. Code and technical values.

## Layout

Spacing is mostly on a 4px grid (76% of measured values), with some off-grid steps. Match the measured scale rather than rounding everything.

- **Scale:** xs 4px, sm 8px, md 12px, lg 20px, xl 64px.
- **Sections:** 112px vertical padding between major sections.
- **Gaps:** 12px is the most common gap in flex and grid layouts.
- **Breakpoints:** 600px, 639px, 640px, 767px, 768px, 1023px, 1024px, 1400px.

## Elevation & Depth

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

- `rgba(1, 2, 4, 0.8) 0px 6px 16px -12px`
- `rgba(0, 225, 255, 0.5) 0px 0px 0px 1px, rgba(0, 225, 255, 0.7) 0px 10px 34px -12px`
- `rgba(0, 225, 255, 0.3) 0px 0px 0px 1px, rgba(0, 225, 255, 0.5) 0px 30px 70px -40px`

## Shapes

Interactive controls are pill-shaped. Measured radii, most used first:

- **full (9999px):** 228 elements.
- **sm (10px):** 32 elements.
- **md (16px):** 12 elements.

## Components

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

- **button-primary (“Start deploying”):** transparent fill, #080D16 text, 14px/600, 10px radius, padding 10px 20px, shadow `rgba(0, 225, 255, 0.5) 0px 0px 0px 1px, rgba(0, 225, 255, 0.7) 0px 10px 34px -12px`.
- **button-outline (“Explore the platform”):** transparent fill, #F8FAFC text, 14px/600, 10px radius, padding 12px 24px, border 1px solid #1F293D.
- **button-outline-hover:** background #00E1FF12, text #F8FAFC on hover.
- **button-ghost (“Start deploying”):** transparent fill, #080D16 text, 14px/600, 10px radius, padding 10px 20px, shadow `rgba(0, 225, 255, 0.5) 0px 0px 0px 1px, rgba(0, 225, 255, 0.7) 0px 10px 34px -12px`.
- **card:** #14192466 fill, #F8FAFCE6 text, 14px/400, 9999px radius, padding 6px 14px, border 1px solid #1F293D.
- **link:** transparent fill, #F8FAFC text, padding 0px.

## Do's and Don'ts

- Do use #0A0D14 for the page and lift surfaces in small steps: #0E141B.
- Do keep text in 4 levels: #F8FAFC, #E1E3E5, #BCBFC2, #909EB2.
- Do use #0A313D as the brand accent: header, logo and key highlights.
- Do set headlines in Space Grotesk with tight tracking (-0.03em).
- Do reuse the measured spacing steps (8px, 12px, 20px).
- Do make buttons and chips fully rounded (9999px); most other elements use 10px corners.
- Don't introduce new font families beyond Space Grotesk, Inter and ui-monospace.
- Don't use #0A313D for large backgrounds or body text.
- Don't make interface transitions slower than 0.36s.

## Motion

Interface transitions are quick: 0.15s, 0.22s, 0.36s, 0.24s.

- **Easing:** `ease`, `cubic-bezier(0.4, 0, 0.2, 1)`, `cubic-bezier(0.2, 0.75, 0.25, 1)`.
- **Reduced motion:** the page responds to `prefers-reduced-motion`.
