# Twilio — Design Reference (measured)

Measured design tokens extracted from `https://www.twilio.com/en-us` 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), 488 observation records.
- Primary action color observed as `#1866ee` (basis: cross-validated, confidence 0.7).
- Dominant font family: **Whitney SSm** (×877; secondary Buffalo ×97).
- Type scale observed at 8 sizes from 12px to 72px.
- Corner radius values in use: 50px, 4px, 20px, 10px….
- 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).

| `{color.primary}` | `#1866ee` | cross-validated | 0.7 | ×66 |
| `{color.background}` | `#ffffff` | cross-validated | 0.94 | ×660 |
| `{color.ink}` | `#000d25` | cross-validated | 0.94 | ×415 |
| `{color.muted}` | `#7e869c` | inferred | 0.7 | ×32 |
| `{color.surface}` | `#cacdd8` | inferred | 0.7 | ×149 |
| `{color.accent}` | `#ef223a` | inferred | 0.65 | ×247 |

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}` (`#1866ee`) for primary actions only — that is where it was observed.
- Default text pairing: `{color.ink}` (`#000d25`) on `{color.background}` (`#ffffff`).
- Set all text in `Whitney SSm` (fallbacks only for glyph coverage).
- Pick corner radii from the measured set (50px, 4px, 20px, 10px) — 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.
