# PostHog — Design Reference (measured)

Measured design tokens extracted from `https://posthog.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), 671 observation records.
- Primary action color observed as `#925d05` (basis: inferred, confidence 0.53).
- Dominant font family: **RoundHog** (×1043; secondary Source Code Pro ×22).
- Type scale observed at 8 sizes from 12px to 30px.
- Corner radius values in use: 4px, 6px, 2px, 8px….
- Not observed in this extraction: nav, forms, badges.

| `{color.background}` | `#1e1f23` | cross-validated | 0.93 | ×328 |
| `{color.ink}` | `#ffffff` | cross-validated | 0.94 | ×439 |
| `{color.muted}` | `#626674` | inferred | 0.7 | ×29 |
| `{color.surface}` | `#000000` | inferred | 0.7 | ×199 |
| `{color.accent}` | `#111827` | inferred | 0.65 | ×34 |

2 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}` (`#925d05`) for primary actions only — that is where it was observed.
- Default text pairing: `{color.ink}` (`#ffffff`) on `{color.background}` (`#1e1f23`).
- Set all text in `RoundHog` (fallbacks only for glyph coverage).
- Pick corner radii from the measured set (4px, 6px, 2px, 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 (nav, forms, 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.
