# Ridi — Design Reference (measured)

Measured design tokens extracted from `https://ridibooks.com/comics/ebook` 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), 816 observation records.
- Primary action color observed as `#1e9eff` (basis: cross-validated, confidence 0.7).
- Dominant font family: **Pretendard Variable** (×4675; secondary Pretendard JP Variable ×238).
- Type scale observed at 8 sizes from 8px to 22px.
- Corner radius values in use: 4px, 18px, 20px, 99px….
- Not observed in this extraction: 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}` | `#1e9eff` | cross-validated | 0.7 | ×30 |
| `{color.background}` | `#f5f5f5` | cross-validated | 0.95 | ×4493 |
| `{color.ink}` | `#141414` | cross-validated | 0.95 | ×1092 |
| `{color.muted}` | `#787878` | inferred | 0.7 | ×985 |
| `{color.surface}` | `#ffffff` | inferred | 0.7 | ×36 |
| `{color.accent}` | `#65082a` | inferred | 0.65 | ×7 |

| `#787878` | `#f5f5f5` | 4.05 | fail | muted_on_background |

7 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}` (`#1e9eff`) for primary actions only — that is where it was observed.
- Default text pairing: `{color.ink}` (`#141414`) on `{color.background}` (`#f5f5f5`).
- Set all text in `Pretendard Variable` (fallbacks only for glyph coverage).
- Pick corner radii from the measured set (4px, 18px, 20px, 99px) — 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 (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.
