The colour never carries meaning on its own - every\n * dot sits beside its written label, so the row still reads for anyone who\n * cannot separate the hues, and the dot is `aria-hidden` rather than announced\n * as a second, colour-shaped copy of the label. And each hue is declared as a\n * LITERAL class pair, `bg-rose-500 dark:bg-rose-400`, because Tailwind only\n * emits what it can see in the source and a template string compiles to\n * nothing.\n *\n * The reset lives in the trigger, where the chevron was, and it is a SIBLING of\n * the trigger rather than a child. `CascaderTrigger` renders a real `<button>`,\n * so a button inside it would be invalid HTML, would fail the\n * `nested-interactive` axe rule, and would open the popup on its way up from\n * its own click. Positioned over the trigger's inline end it gets the same\n * picture and none of that. `showIcon` withdraws the chevron for exactly as\n * long as the reset is standing in for it so the two never stack, `pe-8` holds\n * the space the chevron used to take so the dot and its labels truncate rather\n * than run underneath, and `end-*`/`pe-*` are logical so it all mirrors in RTL.\n *\n * The same reset is then named in the footer, and the two are additive rather\n * than duplicates. The X clears in one press for someone who can already see the\n * field; the footer row is the labelled one, in front of you while the popup is\n * open and a Tab away from the search field now that the panel routes Tab past\n * the scroll area, so it is a usable surface rather than a decoration.\n * `CascaderFooter` draws the rule\n * itself, with a `border-t` that sits exactly on the boundary between the list\n * and the footer. An explicit `CascaderSeparator` in here looked equivalent and\n * was not: it stacks its own block margin on top of BOTH containers' padding,\n * which measured 12px above the rule against 6px below, where the panel's own\n * rhythm is 4px after the search field and 0 between rows. The border needs no\n * arithmetic to be symmetric, because it is the boundary rather than a child of\n * one side of it.\n */\nexport function Pattern() {\n  const [value, setValue] = useState(\"\")\n\n  return (\n    <div className=\"flex w-full justify-center p-4\">\n      <Cascader\n        items={workflow}\n        value={value}\n        onValueChange={setValue}\n        renderLabel={(node, state) =>\n          state.branch ?
