/**
 * Tests for tooltip.ts generator
 *
 * These tests ensure the Tooltip Figma component generation stays in sync
 * with the source of truth (component-registry.json).
 *
 * CRITICAL: These tests act as a regression guard. If you change the tooltip
 * generator or parser, these tests will catch any unintended style changes.
 *
 * Source of truth chain:
 * tooltip.tsx → component-registry.json → tooltip.ts (generator) → Figma
