Detailed Description

Centralized Z-value constants for rendering layer order.

Z-values in Qt determine stacking order. Higher values render on top. These constants define the visual layering hierarchy for the game scene.

Layer Architecture

See z_value_layer_manager.h for detailed documentation on the three-layer architecture (Zone, Card, Overlay) and the rationale for Z-value choices.

Quick Reference

Layer	Z-Value Range	Purpose
Zone	0.5 - 1.0	Zone backgrounds, containers
Card	1.0 - 40,000,000	Cards on table (position-based)
Overlay	2,000,000,000+	UI elements above all cards
