Description:

When working in a 3-panel layout (List view on left, task detail open, Brain panel on right), opening a custom field for editing launches a modal/popover that covers more than half of the Brain panel content.

Steps to reproduce:

Open a List view

Open a task (task detail panel appears)

Open Brain in the right sidebar

While following instructions in Brain, click to edit a custom field on the task

Expected: The custom field editor should not overlap the Brain panel, or should be aware of the Brain panel's position and adjust accordingly.

Actual: The custom field editing window covers over half the Brain panel, making it impossible to read instructions while editing the field.

Impact: Users relying on Brain for step-by-step guidance can't reference instructions while making the changes Brain is telling them to make. Defeats the purpose of the side-by-side workflow.
