# LINE — Design Reference (measured)

Measured design tokens extracted from `https://www.line.me/ko/` by designskill-extract/3.1.0.
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), 276 observation records.
- Primary action color observed as `#07b53b` (basis: cross-validated, confidence 0.67).
- Dominant font family: **SFPro** (×100; secondary LINESeed ×49).
- Type scale observed at 8 sizes from 12px to 60px.
- Corner radius values in use: 4px, 16px, 10px, 8px….
- 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}` | `#07b53b` | cross-validated | 0.67 | ×8 |
| `{color.background}` | `#f6f7f8` | cross-validated | 0.93 | ×177 |
| `{color.ink}` | `#000000` | cross-validated | 0.9 | ×42 |
| `{color.muted}` | `#616161` | inferred | 0.7 | ×30 |
| `{color.accent}` | `#007aff` | inferred | 0.57 | ×2 |

| `#cccccc` | 0.3% | border-color | ×1 (inferred, 0.56) |

## Typography

### Font Families

| Family | Observed |
|---|---|
| `SFPro` | ×100 |
| `LINESeed` | ×49 |
| `slick` | ×3 |
| `swiper-icons` | ×2 |

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

### Type Scale

| Token | Size | Observed |
|---|---|---|
| `{type.display}` | 60px | ×6 |
| `{type.h1}` | 28px | ×10 |
| `{type.h2}` | 20px | ×17 |
| `{type.h3}` | 16px | ×8 |
| `{type.body-lg}` | 15px | ×14 |
| `{type.body}` | 14px | ×44 |
| `{type.body-sm}` | 13px | ×29 |
| `{type.caption}` | 12px | ×26 |

The most frequently observed size is **14px** (×44) — treat it as the default body size.

### Hero Gradient (observed)

```css
background-image: linear-gradient(rgb(178, 178, 178), rgb(178, 178, 178) 2px, rgba(0, 0, 0, 0) 0px, rgba(0, 0, 0, 0) 5px);
```

| `#616161` | `#f6f7f8` | 5.77 | pass | muted_on_background |

5 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}` (`#07b53b`) for primary actions only — that is where it was observed.
- Default text pairing: `{color.ink}` (`#000000`) on `{color.background}` (`#f6f7f8`).
- Set all text in `SFPro` (fallbacks only for glyph coverage).
- Pick corner radii from the measured set (4px, 16px, 10px, 8px) — 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.accent}` with caution — confidence below 0.6.
