Dashboard UI Layouts: 10 Copyable React and Tailwind Admin Screens

import { createElement, useEffect, useMemo, useRef, useState } from "react";
import type { ReactNode, SyntheticEvent } from "react";

/*
  Dashboard UI layouts.
  Every screen is built once as a small tree of elements and Tailwind classes, assembled from
  blocks (sidebar, KPI row, chart, side panel, table). The same tree renders the live preview,
  the React JSX you copy and the plain HTML you copy, for the whole screen or one block.
  Charts are inline SVG computed from the data arrays below.
