📄 Description

Pull Request Checklist

Target branch: This PR targets the dev branch.
Description: Concise description of changes provided below.
Testing: Manually reproduced the issue using the YAML preset linked in #5975 and verified bubble widths stay consistent while scrolling in widescreen mode.
Code review: Self-reviewed — minimal, focused CSS fix only.
Git Hygiene: Single commit, rebased cleanly on dev (1 commit ahead of upstream).

Changelog Entry

Description

Fixes inconsistent message bubble widths when scrolling through conversations containing YAML (or other wide) code blocks in widescreen mode.

Root cause: min-w-full on flex children forces a minimum width equal to the parent container. Without min-w-0, flex children cannot shrink below their intrinsic content size — so wide code blocks push the bubble container wider than intended, causing layout reflow on scroll.

Fixed

ResponseMessage.svelte: replaced min-w-full with min-w-0 on message content containers; added min-w-0 to flex wrapper
UserMessage.svelte: same fix applied to user bubble and edit containers

Additional Information

Fixes issue: Voice mode seems to be broken on desktop web browsers (#5975)
Reproduced with: https://github.com/ChatLunaLab/chatluna-character/blob/main/resources/presets/default.yml
Both files are part of the same fix — they are the two sides of every conversation (user + response). Fixing only one would leave the UI in a broken half-fixed state.
