Shared Style Constants for TUI/WASM Parity

This module provides unified color and style constants to ensure visual consistency between TUI (ratatui) and WASM (Canvas/CSS) renders.

Architecture (OR-001 Compliant)

All visual constants are defined ONCE here and used by both:

• TUI: via ratatui::style::Color conversions
• WASM: via CSS variable injection / Canvas fill styles

References

• WCAG 2.1 AA contrast requirements
• TPS Visual Control (見える化)
