Why this pattern works

Keep customer context and ownership controls above the conversation so agents can read and act without switching screens.

Design notes

Surface: FlexInbox — Conversation and CRM panel
Navigation: A left rail switches between conversations, reports, templates, and CRM tools.
Layout: Three columns separate app navigation, customer threads, and a conversation with its record controls above.
Density: Dense conversation list beside a spacious message canvas.
Color: White and pale gray panels, cyan selection, and pastel avatar circles.
Type: Small sans-serif labels keep tools and content visually separate.
Pattern: Keep customer context and ownership controls above the conversation so agents can read and act without switching screens.
States: This capture records the visible state only. Loading, error, and later workflow states were not verified.
Don't: Adapt the interface pattern with original content, branding, and data; do not infer behavior from a still image.

## Acceptance criteria
- Existing project conventions, design tokens, working functionality, and unrelated changes are preserved.
- Two or three reference principles clearly support the user's task; conflicts are resolved in favor of usability and the existing product.
- Reusable components and semantic HTML express the interface. Available licensed assets are used; important UI text is never rendered as a bitmap.
- Every visible control has a defined behavior. Loading, empty, error, success, disabled, and long-content states are specified where relevant. Demo data is clearly labeled.
- Navigation and content adapt at 375px, 768px, and 1440px without horizontal page overflow. Keyboard use, visible focus, labeled inputs, at least 44px touch targets, readable contrast, and reduced motion are supported.
- Verification distinguishes rendered behavior from proposals and identifies anything still requiring a backend or external service.

## Quality bar
Clear hierarchy, consistent spacing, restrained surfaces, and purposeful motion. Avoid decorative gradients, excessive cards, placeholder buttons, and invented metrics unless the project calls for them. Do not claim a feature is connected or tested without evidence.
