- [x] adopt vamp-style top and bottom bars with a fixed layout, not vamp's configurable segment/tab system.
  - [x] render full-width bars in the outer shell (`src/connection.rs`) before splitting explorer/content; remove the old content-only header (`src/app.rs`, see above).
  - [x] top: `dbdash` badge with vamp-style `▓░` trailing edge; retain provider and READ ONLY information without tab numbering.
  - [x] bottom-left: current mode badge with `▓░` trailing edge, followed by the connected database name; bottom-right: focused input's one-based `line:column` with `░▓` leading edge.
  - [x] capture a safe database display name on successful saved-profile and CLI connections, including SQLite; use the connected database, not explorer selection or `Database::name()` (which returns the provider). Never expose raw connection strings/passwords; show a clear disconnected state and retain the previous identity after a failed switch.
  - [x] add Normal/Insert query editing with mode-aware key routing; define entry/navigation keys and make Esc leave Insert before returning to the explorer. Preserve query execution, multiline editing, paste, and focus cycling.
  - [x] keep connection/password forms direct-entry for now; make the mode indicator reflect the focused surface rather than a stale query mode.
  - [x] expose position from the existing `Input` cursor instead of duplicating state; follow the focused query/form field, hide position outside inputs, and define Unicode column semantics consistently.
  - [x] keep relation/page/column status in pane borders and accommodate the separate help pane; do not add tabs, title templates, custom segments, or editor-specific status.
  - [x] handle narrow/short terminals without overlapping content: truncate the database label before mode/position, and let bars yield to content when height is insufficient.
  - [x] verify mode transitions/key precedence, focused-input Unicode positions, connection identity on successful/failed switches, and constrained layouts; smoke-run the TUI and ask for a visual check.
- [x] pressing `i` on a configured database connection should bring up a floating window with details/info on that connection.
- [x] show a `*` to the right of the connected db in the sidebar.
- [x] use the proper ending character in the family of `├` instead of that character all the way down.
- [x] remove this top-most line above the panels on the right-hand side: `dbdash │ SQLite │ READ ONLY`.
- [x] highlight the current cell isntead of just the current row in the results pane.
- [x] put the help text inside it's own pane so it fits the design more cleanly.
