 - `widgets/` holds simple first-party bar widgets with sibling manifests.
 - Feature plugins such as `../panels/audio/`, `../panels/network/`, and `../panels/power/` provide richer popup bar plugins.
 - The bar receives its config from the host shell as a `barConfig` property; the host loads it from `~/.config/blob/shell.json` (or `config/blob/shell.json` when the user has no file).
-- `blob bar position` updates only the user shell.json file.
+- The bar is locked to the top edge. A `bar.position` left in shell.json is ignored.
 
 ## Customizing
 
 The bar config lives under the `bar:` key of [`~/.config/blob/shell.json`](../../README.md#shelljson-shape). Out of the box the shell uses [`config/blob/shell.json`](../../../config/blob/shell.json). Once you customize anything via the bar gestures, `blob bar ...`, or by editing shell.json directly, your file is canonical — there is no deep-merge.
 
-The bar is configured directly on the bar itself: drag empty bar space (or click-and-hold) to move the bar to another screen edge, double-left-click empty center-bar space to toggle transparency, and drag widgets to reorder them. The `blob bar position`, `blob bar transparent`, `blob bar move`, and `blob bar set` commands do the same from scripts. Enable or disable widgets with `blob plugin enable` and `blob plugin disable` (widget ids come from `blob plugin list`).

 ## Orientation
 
-All widgets work in `top`, `bottom`, `left`, and `right` positions. Popups anchor on the side opposite the bar edge, sliding into the workspace. Vertical bars use 28px width; widgets that show text fall back to compact icon-only forms (e.g. `media` hides its scrolling label).
