e2e-chatbot-app-next: markdown list markers missing (Tailwind v4 does not scan node_modules for Streamdown classes)

[AndreasJaeck]

Summary

Ordered and unordered lists in assistant markdown render with no bullets and no numbers.

Root cause

client/src/index.css L2 is @import "tailwindcss"; (Tailwind v4) and the file declares no @source.

Tailwind v4 excludes node_modules from automatic class scanning. Streamdown (streamdown@^1.4.0) emits the list utilities — list-disc, list-decimal and friends — from inside node_modules/streamdown/dist/*.js, so Tailwind never sees those class names and never generates the corresponding CSS.

Meanwhile Tailwind's Preflight resets ul / ol to list-style: none. The reset lands, the utilities that would restore the markers do not, and the markers disappear.

Reproduction

1. Run e2e-chatbot-app-next.
2. Ask the model for a bulleted or a numbered list.
3. The list items render as unmarked lines.

Fix

Add an explicit source directive to client/src/index.css after the Tailwind import:

@import "tailwindcss";
@source "../../node_modules/streamdown/dist/*.js";

This is what we run with and it restores markers for both list types.
