Summary

The top-level draw function of a ratatui messaging client: a vertical split giving the main area all but one row (Fill(1) + Length(1) status row) with the main area itself split 30/70 between chat list and conversation. The focused pane gets a provider-accent border; unfocused panes do not.

Key findings

• draw_main splits vertically into Fill(1) main content plus a Length(1) status row, then splits the main area horizontally 30% / 70%.
• Only the focused pane carries a provider-accent border; inactive panes render without the accent, making focus visible at a glance.

Pros / strengths

• Clean separation of layout (this file) from focus state, status content, and message rendering (sibling modules), so each piece can be studied alone.
• Focus-indicating border accent is a cheap, effective focus signal worth copying.

Cons / limitations / caveats

• This file alone shows only the split skeleton; focus, status text, and message rows live in sibling modules and must be read with it.
• No narrow-terminal breakpoint; the 30/70 split is unconditional.

Relevance to tai

• Confirms the 30/70 + 1-line-status skeleton as the shared convention across inspected ratatui messaging clients, and contributes the focused-pane-accent pattern to the messaging-layout conclusion.
