Use PostHog's system on your site

Paste this into Claude Code, Cursor or any agent with plagio connected. It reads the site live, with spacing, radii, shadows and the states this page leaves out.

Use plagio's extract_brand on https://posthog.com, then restyle my site with its colours, type scale and spacing. Keep my content, layout and logo; take the system, not PostHog's copy.
