Editor / row detail / command bar / search bar render as overlays on top of the main panels (not their own region).

Schema tree (left)

Shows tables and views in a flat list grouped by type.

j / k to navigate
Enter / l / Right to expand or load a table
h / Left to collapse

Data grid (right)

Column-aware row viewer.

j / k to move row
h / l to scroll columns
Enter to open the row-detail overlay
r to reload

Status bar

One line, ordered:

Field	Source
Current table	`—` if none
Row count	`N rows`
Elapsed	`Nms`
Server version	from the engine's handshake
RO / RW badge	yellow `RO` / green `RW`
Context-sensitive hints	`r`, `:ro`, `/`, etc.

The status bar does not show the connection name, database, or a timestamp.

SQL editor overlay

e from anywhere opens an editor at 70% × 50%. Ctrl+R runs the buffer (despite what the footer docstring says — it's Ctrl+R, not Ctrl+Enter).

Row detail overlay

Enter on a row — Esc to close.
