/**
 * Provides an Emotion cache to the component tree.  Handles two concerns:
 *
 * 1. **CSP nonce** — when a `<meta property="csp-nonce">` tag is present, a
 *    cache carrying that nonce is created so Emotion's `<style>` tags comply
 *    with Content Security Policy.
 *
 * 2. **CSS selector prefix** — when `cssSelectorPrefix` is provided, a Stylis
 *    plugin is installed that prepends the selector to every compiled CSS rule,
 *    increasing specificity so CSDK styles win over host-app overrides.
 *
 * The component is designed to be used at two levels:
 *
 * - **Top-level** (in `SisenseContextProvider`, no `cssSelectorPrefix` prop) —
 *   creates a nonce-only cache if needed and establishes the internal context
 *   so nested instances can detect they are not the first provider.
 *
 * - **Nested** (in `ThemeProvider`, with `cssSelectorPrefix` prop) — compares
 *   the requested prefix against the ancestor's value via `EmotionCacheContext`.
 *   A new cache is created only when the prefix has actually changed; otherwise
 *   children are rendered as-is, reusing the ancestor's cache.
 *
 * When a nested provider creates a cache (nonce is always included when present),
 * it also updates `EmotionCacheContext` so that further nested providers can
 * detect the new prefix value and avoid creating duplicate caches.
