/* ---- Versioning sidebar --------------------------------------------------
 *
 * Lives here rather than in the UI packages: every rule below was identical
 * across the ariakit/mantine/shadcn stylesheets, and none of it is
 * library-specific. Per-package overrides belong in those stylesheets, scoped
 * to `.bn-ariakit` / `.bn-mantine` / `.bn-shadcn` (see the Mantine
 * `.bn-threads-sidebar` override for the pattern).
 *
 * Resembles `.bn-threads-sidebar` above, but shares almost nothing with it
 * concretely: the shells have only `overflow: auto` in common (this one is a
 * flex *item* whose rows self-space via `margin-bottom`, not a flex column),
 * and the two selected states are deliberately different designs — a filled
 * accent with inverted text here, a pale tint with a saturated border there.
 * The row boxes look closer, but only against `.bn-mantine .bn-thread`:
 * ariakit and shadcn get their thread boxes from their own component
 * libraries, which BlockNote's CSS doesn't touch. A shared base class would
 * hold ~3 declarations and still leave every caller overriding gap, border,
 * radius, padding and width — so these are kept separate on purpose.
