/**
 * Portal-container context (#1208).
 *
 * Radix overlays (dropdown menu, select, tooltip, dialog) portal to the
 * document body by default. When a workspace panel is popped out into a
 * separate OS / PiP window (#1208), its menus must portal into THAT window's
 * document instead of the original tab — otherwise a Script panel's dropdowns
 * and dialogs render in the main window (behind it / off-screen).
 *
 * `PanelWindowChrome` wraps the popped-out panel in a provider pointing at the
 * child window's `document.body`; the shared UI primitives read this and pass
 * it to their Radix `*.Portal container` prop. The default is `undefined`, so
 * normal (main-window) usage is unchanged.
