/**
|
|
* JavaScript enhancement to the collapsible sidebar.
|
|
*
|
|
* The sidebar provides basic show/hide functionality with CSS
|
|
* but JavaScript is used for progressive enhancements.
|
|
*
|
|
* Enhancements include:
|
|
* - Update `aria-role`s based on expanded/collapsed state.
|
|
* - Update button icon based on expanded/collapsed state.
|
|
* - Persist the sidebar state for logged-in users.
