About the Noir Aurora Section

A page band: vertical rhythm, tone and width. Every block on a page sits in one. Sets data-tone; inverse and accent also set data-surface, so every component inside reads correctly. Two adjacent default sections share one gap. In Noir, accent is the aurora night band (green-lit night with a sky glow from the top, in both themes), inverse a paper band on Night (at most once per page), muted a slightly lifted night. Bands have no borders; separate two default bands with a HorizonSweep or nothing.

It is part of Noir Aurora. The style’s 91 pieces share one set of tokens, type and motion, in a light and a dark theme, so whatever you take from it fits together.

To put it in your project, copy the prompt into Claude Code, OpenAI Codex or Cursor, or add the file and its styles by hand. The documentation walks through both.
