# Velog — Design Reference (measured)

Measured design tokens extracted from `https://velog.io/` by designskill-extract/3.2.0.
Every value below was observed in the live page (×N = observation count). Values not listed were **not observed** — do not invent them.
This document is `reference_only`: an analysis of a third-party site, not a license to its brand assets.

## Overview

- Extraction mode: **full-render** (viewports 390/768/1440px × light/dark), 1 page(s), 322 observation records.
- Primary action color observed as `#12b886` (basis: inferred, confidence 0.52).
- Dominant font family: **-apple-system** (×1544; secondary KaTeX_Main ×8).
- Type scale observed at 7 sizes from 12px to 32px.
- Corner radius values in use: 4px, 16px, 12px, 24px.
- Not observed in this extraction: forms, cards, badges.

## Colors

### Role Tokens

Semantic roles inferred from observed usage. `basis` tells how the role was established (declared CSS var > cross-validated > inferred).

| Token | Value | Basis | Confidence | Observed |
|---|---|---|---|---|
| `{color.primary}` | `#12b886` | inferred | 0.52 | ×5 |
| `{color.background}` | `#ffffff` | cross-validated | 0.94 | ×411 |
| `{color.ink}` | `#212529` | cross-validated | 0.94 | ×546 |
| `{color.muted}` | `#868e96` | inferred | 0.7 | ×758 |
| `{color.surface}` | `#dee2e6` | inferred | 0.7 | ×109 |
| `{color.accent}` | `#f0f0f0` | declared | 0.9 | ×0 — --accent1 |

## Typography

### Font Families

| Family | Observed |
|---|---|
| `-apple-system` | ×1544 |
| `KaTeX_Main` | ×8 |
| `KaTeX_SansSerif` | ×7 |
| `KaTeX_Math` | ×4 |
| `KaTeX_Size1` | ×4 |
| `Fira Mono` | ×3 |

Use **-apple-system** as the default family — it accounts for the overwhelming majority of observed text nodes.

### Type Scale

| Token | Size | Observed |
|---|---|---|
| `{type.display}` | 32px | ×7 |
| `{type.h1}` | 24px | ×15 |
| `{type.h2}` | 20px | ×8 |
| `{type.h3}` | 18px | ×39 |
| `{type.body-lg}` | 16px | ×278 |
| `{type.body}` | 14px | ×290 |
| `{type.body-sm}` | 12px | ×1018 |

The most frequently observed size is **12px** (×1018) — treat it as the default body size.

## Components

Measured computed styles of representative components (desktop viewport).

| Component | Measured spec | Samples |
|---|---|---|
| button.primary | bg `#212529` · text `#ffffff` · radius `16px` · padding `1px 16px` · font `16px/700` | ×2 |
| nav | height `64px` · position `static` · link `#000000` | — |

## Accessibility (WCAG Contrast)

| FG | BG | Ratio | AA | Source |
|---|---|---|---|---|
| `#868e96` | `#ffffff` | 3.32 | fail | observed ×369 |
| `#212529` | `#ffffff` | 15.43 | pass | observed ×258 |
| `#495057` | `#ffffff` | 8.18 | pass | observed ×126 |
| `#868e96` | `#f8f9fa` | 3.15 | fail | observed ×9 |
| `#ffffff` | `#212529` | 15.43 | pass | observed ×6 |
| `#212529` | `#f8f9fa` | 14.63 | pass | observed ×3 |
| `#212529` | `#ffffff` | 15.43 | pass | ink_on_background |
| `#ffffff` | `#12b886` | 2.55 | fail | white_on_primary |
| `#868e96` | `#ffffff` | 3.32 | fail | muted_on_background |

4 measured pair(s) fail AA — if you reuse those pairs, adjust lightness until the ratio reaches 4.5:1.

## Usage Rules

### Do
- Use `{color.primary}` (`#12b886`) for primary actions only — that is where it was observed.
- Default text pairing: `{color.ink}` (`#212529`) on `{color.background}` (`#ffffff`).
- Set all text in `-apple-system` (fallbacks only for glyph coverage).
- Pick corner radii from the measured set (4px, 16px, 12px, 24px) — no intermediate values were observed.
- Cite this file's token names (`{color.*}`, `{type.*}`) when generating UI so output stays traceable to observations.

### Don't
- Don't invent colors, sizes, shadows, or spacing not listed above — absence means *not observed*, and this document records observations only.
- Don't assume the missing blocks (forms, cards, badges) don't exist on the site — they were simply not captured in this run.
- Don't copy brand assets (logo, wordmark, imagery, copy) — `reference_only` covers measured style values, not brand identity.
- Treat `{color.primary}` with caution — confidence below 0.6.
