Add min-width: 0 to .shiny-chat-messages-wrapper so the grid child can shrink below its content size. Without it, the auto-fit suggestion-card grid forces the messages/greeting subtree to its max-content width, overflowing the chat container in narrow spaces like sidebars.

The greeting / suggestion-cards feature could overflow the chat area in narrow containers such as Shiny sidebars, pushing cards past the visible edge.
Cause
The suggestion-card grid uses an auto-fit track (
repeat(auto-fit, minmax(min(175px, 100%), 1fr))). Its max-content width propagated up the messages/greeting subtree because the grid item defaulted tomin-width: auto, sizing the chat content to its content width rather than the available container width.Fix
Add
min-width: 0to.shiny-chat-messages-wrapperso the grid child can shrink below its content size. Any residual scrollbar-gutter offset is absorbed by the wrapper's existingoverflow: clip.Verified across 250px / 350px / 500px container widths that the cards and greeting stay within the chat container.
