// @vitest-environment jsdom
/**
 * SearchBar — client-side search/filter for secret key names.
 *
 * Per spec §9:
 *   - Filters KeyNameLabel text, case-insensitive, on every keystroke
 *   - Escape clears search (does NOT close panel) + blurs input
 *   - Cmd+F / Ctrl+F focuses search when panel is open
 *   - Icon is aria-hidden (decorative)
 *
 * NOTE: No @testing-library/jest-dom import — use DOM APIs.
 *
 * Covers:
 *   - Renders search icon with aria-hidden
 *   - Input has correct aria-label
 *   - Input renders placeholder text
 *   - Input has correct class name
 *   - Renders empty initially (searchQuery from store)
 *   - onChange updates searchQuery in store
 *   - Escape clears searchQuery and blurs input
 *   - Escape does not propagate (does not close panel)
 *   - Ctrl+F / Cmd+F focuses the input
