# Vite Design System

## Overview

Vite describes itself as: “Next Generation Frontend Tooling” The interface is dark, built on **Cool Charcoal (#16171D)** with **White (#FFFFFF)** text, and **Light Blue (#9AC8FF)** as the main accent.

Type is set in **APK Protocol** and **Inter**, with **KH Teka Mono** for code. Headlines run large with tight negative tracking; body text is 16px. The surface language is flat. Corners are mostly 8px.

Measured from [vite.dev](https://vite.dev/) on October 21, 2026 at 1440×900 and 390×844 from 228 rendered elements. Values are computed styles from the live page, not the original source files.

## Colors

The palette has 11 roles.

- **Cool Charcoal (#16171D):** Page background, seen 5 times. Token `background`, CSS `--vp-local-nav-bg-color`.
- **White (#FFFFFF):** Primary text and headings, seen 56 times. Token `on-surface`, CSS `--docsearch-sidepanel-hit-color`.
- **Silver (#BABABC):** Secondary text, seen 17 times. Token `on-surface-variant`.
- **Cool Gray (#98989F):** Muted text and metadata, seen 10 times. Token `on-surface-muted`, CSS `--vp-code-line-number-color`.
- **Cool Gray (#867E8E):** Subtle text and placeholders, seen 21 times. Token `on-surface-subtle`.
- **Cool Charcoal (#14121A):** Raised areas one step from the page, seen 10 times. Token `surface-container-low`, CSS `--docsearch-background-color`.
- **Cool Graphite (#3B3440):** Borders and dividers, seen 62 times. Token `outline`, CSS `--color-nickel`.
- **Graphite (#2E2E32):** Secondary dividers, seen 1 time. Token `outline-variant`.
- **Light Blue (#9AC8FF):** Brand accent (CSS variable). Token `primary`.
- **Near Black (#000000):** Text and icons on primary. Token `on-primary`.
- **Light Violet (#B39AFF):** Most used accent color, seen 5 times. Token `secondary`, CSS `--vp-c-note-1`.

## Typography

**APK Protocol**, **Inter** and **KH Teka Mono** (monospace) share the interface. Fallback stack: `APK Protocol, sans-serif`.

- **headline-display:** APK Protocol 60px at weight 500, line height 1.12, tracking -0.05em (36px on mobile). Page title (h1).
- **headline-lg:** APK Protocol 48px at weight 500, line height 1, tracking -0.025em (30px on mobile). Section headings (h2).
- **headline-md:** APK Protocol 40px at weight 500, line height 1.33, tracking -0.025em (24px on mobile). Sub-section headings.
- **headline-sm:** APK Protocol 24px at weight 500, line height 1.17. Card and feature titles.
- **body-md:** Inter 16px at weight 400, line height 1.4. Body text.
- **body-lg:** Inter 18px at weight 400, line height 1.56. Lead paragraphs.
- **body-sm:** Inter 14px at weight 400, line height 1.43. Secondary and small text.
- **label-md:** APK Protocol 16px at weight 400, line height 1.5. Buttons, navigation and labels.
- **label-sm:** Inter 14px at weight 500. Small labels and badges.
- **code:** KH Teka Mono 12px at weight 400, line height 1.33, tracking 0.025em, uppercase. Code and technical values.

## Layout

Spacing follows a 4px grid: 99% of measured gaps and paddings are multiples of 4px.

- **Scale:** xs 4px, sm 8px, md 12px, lg 32px, xl 40px.
- **Sections:** 112px vertical padding between major sections.
- **Gaps:** 24px is the most common gap in flex and grid layouts.
- **Container:** content is capped at 1440px.
- **Page margin:** 40px on each side of full-width sections.

## Elevation & Depth

The design is flat: no shadows were measured. Hierarchy comes from tonal surface steps (#14121A) and #3B3440 borders.

## Shapes

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

- **md (8px):** 56 elements.
- **sm (4px):** 4 elements.

## Components

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

- **button-outline (“Search Ctrl K”):** #14121A fill, #98989F text, 14px/400, 8px radius, padding 8px 12px.
- **button-secondary (“Get Started”):** #CCCCCC fill, #FFFFFF text, 16px/500, 11px radius, padding 8px 16px.
- **button-ghost (“Resources”):** transparent fill, #FFFFFF text, 16px/400, padding 8px 12px.
- **link:** transparent fill, #FFFFFF text, padding 0px.

## Do's and Don'ts

- Do use #16171D for the page and lift surfaces in small steps: #14121A.
- Do keep text in 4 levels: #FFFFFF, #BABABC, #98989F, #867E8E.
- Do use #9AC8FF as the brand accent: header, logo and key highlights.
- Do set headlines in APK Protocol with tight tracking (-0.05em).
- Do keep spacing on the 4px grid.
- Do use 8px corners on most elements; larger surfaces also use 4px.
- Don't add drop shadows for depth; use tonal surfaces.
- Don't introduce new font families beyond APK Protocol, Inter and KH Teka Mono.
- Don't use #9AC8FF for large backgrounds or body text.
- Don't make interface transitions slower than 0.001s.

## Motion

Interface transitions are quick: 0.001s.

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