/**
 * +page.svelte keyboard shortcut tests
 *
 * Tests the pure decision logic for the Ctrl+C keyboard shortcut handler.
 * The handler should only intercept Ctrl+C (to send an interrupt signal) when:
 *   - Claude is currently processing a request, AND
 *   - No text is currently selected (so normal copy behaviour is preserved)
 *
 * Manual testing checklist:
 * - [ ] Ctrl+C with text selected copies the text (browser default)
 * - [ ] Ctrl+C with no text selected and Claude processing sends an interrupt
 * - [ ] Ctrl+C with no text selected and Claude idle does nothing special
