About the Neo-Brutal Border Beam
A hard volt dash that travels along the inside of its parent's 2 px border: put it inside a relative parent with a border, and it takes the parent's radius and clips itself. One lap when it comes into view, then it parks out of sight; loop keeps it orbiting. Under reduced motion there is no beam. One per page at most (the newest feature or a launch card); the landing uses none.
It is part of Neo-Brutal. The style’s 92 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.
Soft Bento Border Beam
A soft rim light that travels along its parent's edge (white on the blue block): put it inside a relative parent and it takes the parent's radius.
Swiss Tech Mono Border Beam
A hard lime segment with an ink caret at its head, running along its parent's border (no glow): put it inside a relative parent with a border, and it takes the parent's radius and clips itself.
