/**
 * This script is loaded in testing environments to set up the
 * document based on URL parameters.
 * 
 * Test pages (e.g., `chip/test/basic/index.html`) are set to use
 * URL query parameters.
 * 
 * Playwright test environments (e.g., `chip/test/basic/chip.e2e.ts`)
 * are set based on whether `setContent` or `goto` has been used:
 * - `setContent` uses URL hash parameters. Tests will break if
 * query parameters are used.
 * - `goto` uses URL query parameters.
 * 
 * The following URL parameters are supported:
 * - `rtl`: Set to `true` to enable right-to-left directionality.
 * - `ionic:_testing`: Set to `true` to identify testing environments.
 * - `ionic:mode`: Set to `ios` or `md` to load a specific mode.
 * Defaults to `md`.
 * - `palette`: Set to `light`, `dark`, `high-contrast`, or 
 * `high-contrast-dark` to load a specific palette. Defaults to `light`.
