/**
 * Canvas Healer — Self-healing loop for Figma canvas operations.
 *
 * After any canvas modification, runs the cycle:
 *   CREATE → SCREENSHOT → ANALYZE → FIX → VERIFY
 * with a configurable max number of rounds (default 3).
 *
 * Analysis checks for the 8 known anti-patterns:
 *   1. "hug contents" instead of "fill container"
 *   2. Padding inconsistencies
 *   3. Text not using "fill" width
 *   4. Centering issues
 *   5. Floating elements outside parent
 *   6. Raw hex values (should be tokens/variables)
 *   7. Missing auto-layout
 *   8. Shadow effects missing blendMode: "NORMAL"
