# Amplitude — Design Reference (measured)

Measured design tokens extracted from `https://amplitude.com/` 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), 990 observation records.
- Primary action color observed as `#000000` (basis: declared, confidence 0.92).
- Dominant font family: **Twemoji Country Flags** (×1711; secondary IBM Plex Mono ×106).
- Type scale observed at 8 sizes from 12px to 44px.
- Corner radius values in use: 6px, 10px, 8px, 12px….
- Not observed in this extraction: forms.

3 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}` (`#000000`) for primary actions only — that is where it was observed.
- Default text pairing: `{color.ink}` (`#171717`) on `{color.background}` (`#ffffff`).
- Set all text in `Twemoji Country Flags` (fallbacks only for glyph coverage).
- Pick corner radii from the measured set (6px, 10px, 8px, 12px) — 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) 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.
