/**
 * ThoughtChain — the assistant's reasoning, step by step (Ant Design X `ThoughtChain`).
 *
 * ## The shape, and why it is an `<ol>`
 *
 * Ant renders the whole chain as nested `<div>`s and paints the step number itself
 * (`index + 1` in `es/thought-chain/Node.js`). The order of the steps IS the content here — step 3
 * only makes sense after step 2 — so the chain is an ordered list and a screen reader gets "list,
 * 4 items" plus each step's position for free. The visible ordinal stays, because the same number
 * has to be on screen for a sighted reader following a long chain.
 *
 * ## The disclosure is a real button
 *
 * A `collapsible` step's title in Ant is a `<div onClick>` with a rotating chevron — no role, no
 * `tabIndex`, no `aria-expanded`. Here it is a `<button aria-expanded aria-controls>` over the
 * body it opens: the WAI-ARIA APG Disclosure pattern, so the step can be opened from the keyboard
 * and its state is announced rather than inferred from a rotation.
 *
 * Everything a caller passes keeps Ant's spelling: `items` (with `icon`, `title`, `description`,
 * `content`, `footer`, `status`, `collapsible`, `blink`, `destroyOnHidden`), the
 * `defaultExpandedKeys` / `expandedKeys` / `onExpand` triad, and `line`. `styles` / `classNames` /
 * `prefixCls` / `rootClassName` are not ported — the standing style-hole decision
 * (docs/WHAT-BELONGS-HERE.md, docs/DESIGN-AUTHORITY.md); the chain is retuned through
 * `src/tokens/components/thought-chain.css`.

/**
 * ThoughtChainItem — one step OUTSIDE a chain (Ant Design X `ThoughtChain.Item`).
 *
 * A named export rather than `ThoughtChain.Item`, for the same reason `ActionsItem` is: every
 * compound in this library is separate named exports (`CardHeader`, `TabsList`), and attaching
 * statics to one component would be the only instance of it here.
 *
 * ONE DEVIATION: Ant renders the chip as a `<div>` and hangs `onClick` on it, so a clickable step
 * is invisible to the keyboard and to assistive technology. Here an item WITH `onClick` renders a
 * real `<button>` and one without renders a plain `<div>` — the element follows whether the thing
 * is actually a control.
