Markdown Preview Styling in IntelliJ

A lot of AI agent output is Markdown (plans, CLAUDE.md, review reports). A light preview stylesheet is checked in at markdown-preview.css.

Enabling the stylesheet

Settings → Languages & Frameworks → Markdown → Custom CSS → Load from and point it at docs/modules/developer/attachments/markdown-preview.css.

Scope

This only affects the Markdown preview. The AsciiDoc preview used for the docs themselves has its own stylesheet setting under Settings → Languages & Frameworks → AsciiDoc.
