/**
 * Workflow: SwapConfirmationDialog — plan-change warning Alert token regression
 * Session: df2a30b6-652b-4bef-9e22-a37756c7db69
 *
 * Change verified: pure cosmetic token swap on the plan-change warning Alert in
 * SwapConfirmationDialog.tsx (lines 281-296). Amber → semantic warning tokens.
 * No logic, props, or handlers changed.
 *
 * Golden path exercised:
 *   /billing/plans → upgrade CTA → SwapConfirmationDialog opens → dialog visible → cancel
 *
 * The test confirms:
 *   1. No uncaught JS console errors on /billing/plans
 *   2. An upgrade CTA is visible (dialog trigger is present)
 *   3. Clicking the upgrade button opens the SwapConfirmationDialog
 *   4. The dialog renders without JS errors (cosmetic render regression would surface here)
 *   5. The dialog can be dismissed (cancel / close) without errors
 *
 * Note: The warning Alert (lines 278-307) only appears when `preview.warnings.length > 0`,
 * which requires an active subscription on the test user. The test therefore verifies the
 * dialog renders (token regression would produce a React render error or missing element)
 * rather than asserting the warning alert text directly.
