What's Wrong?

Component: VS Code extension (chat panel input)
Version: Claude Code extension 2.1.270, VS Code 1.135.0, Windows 10 Home 10.0.19045 (win32-x64)

Issue
Since a recent update, the chat input box is framed with a persistent saturated
red outline in Auto mode and an orange outline in Manual mode. The border stays
on the whole time the mode is active.

Why this is an accessibility problem
I'm autistic. A permanent, high-saturation red frame around the element I look
at all day is a constant sensory overload. Red and orange also read as "error" and
"warning", so the UI is effectively raising an alarm about a mode I selected
deliberately. The result is that I cannot focus on programming while the panel
is open. Both of the modes I actually use are affected, so there is no
colour-neutral option (you only left less useful modes with neutral, non-aggravating colors).

There is no setting to disable or recolour the border, and
workbench.colorCustomizations does not reach it.
This is a very important issue for me, since I cannot turn off my neurodivergence,
and the color is causing me an entirely avoidable (if you supplied ANY kind of customization)
anxiety. It is a very bad update.

Do not force distressing things on neurodivergent users.

Expected
A mode indicator that does not use alarm colours as a persistent frame.
Suggestions (any one would solve it):

• A setting to disable mode-coloured borders.
• A neutral or theme-derived border colour, with the mode shown by the

existing text label instead.

• Reduce the border to a transient cue (e.g. shown briefly on mode change).

Steps to reproduce

1. Open the Claude Code chat panel in VS Code.
2. Switch permission mode to Auto (or Manual).
3. Observe the input box outline.

What Should Happen?

Do not show orange/red and cause me personal distress via constant sensory overload OR provide me with an option to customize colors. A neutral border, or a setting to disable mode-coloured borders. Any of the three suggestions above resolves it.
