📄 Description

Summary

Fixes the inconsistent conversation bubble sizing reported in #5975.

The root cause is that the .markdown-prose class applies Tailwind's prose plugin, which sets a default max-width: 65ch. This conflicts with the explicit w-full min-w-full on message containers. When content like YAML code blocks exceeds the 65ch character limit, the prose max-width constraint causes the bubble to resize inconsistently as the browser recalculates layout during scrolling.

The fix adds max-w-none to .markdown-prose, removing the prose plugin's default max-width. The parent Message component already controls the overall container width via max-w-5xl (normal mode) or max-w-full (widescreen mode), so no additional width constraint is needed on the prose wrapper. Code blocks continue to handle horizontal overflow correctly via their existing overflow-x-auto.

The root cause is that the `.markdown-prose` class applies Tailwind's `prose` plugin, which sets a default `max-width: 65ch`. This conflicts with the explicit `w-full min-w-full` on message containers. When content like YAML code blocks exceeds the 65ch character limit, the prose max-width constraint causes the bubble to resize inconsistently as the browser recalculates layout during scrolling. The fix adds `max-w-none` to `.markdown-prose`, removing the prose plugin's default max-width.
