/**
 * <SidebarFloatingInset> — the "inset" sidebar: a floating card on a tinted
 * canvas, with the page content sitting in a second rounded surface beside it
 * rather than butting against a hairline.
 *
 *  - Both surfaces are cards on a `bg-muted` canvas, so the gap between them
 *    is the separator. No border-e to flip in RTL; the layout mirrors from
 *    flex order alone.
 *  - The usage meter is a real `role="progressbar"` with a value and a name.
 *    A bare coloured bar is invisible to a screen reader, and a number in the
 *    caption alone is not a progressbar.
 *  - The promo card is a labelled region with one button, not a link farm, so
 *    it can be skipped past in a single Tab stop when the user does not want it.

Before you paste

Styling is Tailwind utility classes on semantic tokens (bg-card, text-muted-foreground) — it inherits your theme instead of overriding it.
Install: npm i lucide-react
Every prop has a default, so it renders standalone before you wire it up.

Where it goes

Drop it at components/sidebar-floating-inset.tsx and import it where you need the section:

import { SidebarFloatingInset } from '@/components/sidebar-floating-inset'

Customize

2 of this block’s props are simple enough to drive from here. Change them and the block below re-renders — it is the same component whose source is above, not a mock of it. Everything else it accepts is in the table underneath.

Props

Read out of the component’s own type and signature, so this cannot drift from the source below. Every prop has a default — the component renders standalone before you pass it anything.

Prop	Type	Default
`items`	`FloatingItem[]`	`DEFAULT_ITEMS`
`defaultActiveId`	`string`	`'board'`
`used`Percent of the plan used, 0-100.	`number`	`72`
`children`	`React.ReactNode`	—
`className`	`string`	`''`

Not using React?

The same block rendered once to markup, wrapped as a file your framework compiles. Tailwind classes are framework-agnostic, so the design transfers intact — the behaviour does not.

This block is interactive. The markup below is its initial state with the event handlers stripped — you will need to re-wire the behaviour in your framework.

sidebar-floating-inset.html

<!--
  Floating Inset Sidebar — markup from the Hoverlab catalog.

  This is the block rendered once to HTML and wrapped as a component
  file. It is not a port of the React source: the Tailwind classes carry
  the design, which is the part that took the work, and they are the same
  in every framework.

  This block is interactive in React and the handlers are NOT here.
  Buttons, toggles and menus render in their initial state and do
  nothing until you wire them up.

This is rendered HTML, not a translation of the React source. The Tailwind classes carry the design and work in any framework.
It is one frame: the component in its initial state, with no props applied beyond the defaults.
This block is interactive in React — toggles, menus or form state. None of that survives here; the markup is the closed/default state and the handlers are gone. Re-wire them in your own framework.
Requires Tailwind, and the design tokens the classes reference (bg-card, text-muted-foreground, and so on). The template ZIPs ship a globals.css that defines them.

What each framework gets across the whole catalog — effects convert properly; this rung is markup.

For AI

The component, its props, the design tokens it expects and the command that installs it — as one prompt. Paste it into Claude, Cursor, v0 or ChatGPT and what they build around it will match the rest of the catalog instead of inventing its own system.
