Langfuse — design system & UI screens
Light docs-style landing with a left resource sidebar; a highlighter-yellow headline, a model cost-and-latency tracking dashboard, and a customer logo wall (Twilio, Khan Academy, Cisco, Intuit).
This is a static, crawlable rendering for search & AI engines. The interactive version — filters, live decode console, copy & export — is at https://mozaika.design/website/langfuse.
Decoded design system
Langfuse's decoded design system: background #EDEDE8, text #020817, accent #1863DC, link #020817, primary #1863DC; type scale h1 68px / h2 32px / body 18px; 4px spacing base; 2px base radius. The single interactive/action color is #1863DC — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Using these colors
- Action color
#1863DC— the single interactive color; only on things you click or must notice, never large fills. primary,accent,button_bgare all#1863DC— one role, not several (the action color).- accent
#1863DC— THE accent / action color — interactive & must-notice only (buttons, links, focus, one key highlight); never large fills or backgrounds. Scarcity is what makes it read as designed. - link
#020817— inline text links and link-styled controls. - secondary
#4E4B66— optional secondary accent — LOW decode confidence; use rarely (a status color or a single decorative moment) or omit it entirely. Prefer one accent unless the reference clearly shows two.
