Motivation

• The previous wood texture was reported as too rough/noisy and visually inconsistent with a typical chess/board-game aesthetic.
• The goal is to provide a cleaner, warmer, and more natural-looking board and piece materials to improve clarity and user experience while keeping existing interactions intact.

Description

• Reworked the board material in styles.css to use softer wood gradients, subtler grain layering, increased border depth, and refined inset/drop shadows for a tabletop look.
• Tuned grid line color and opacity and adjusted node hotspot styling so lines and intersection dots harmonize with the warmer board tone.
• Updated black/white piece materials in styles.css to improve highlights, shadowing, and subtle texture layers so pieces appear polished and legible, and preserved the existing hint/selection visual styles.
• Kept script.js logic unchanged and ensured the new styles integrate with the rule-selection hints and UI elements defined in index.html and styles.css.

Testing

• Ran node --check script.js which completed with no syntax errors (passed).
• Served the app using python3 -m http.server 4173 and confirmed the page assets loaded successfully (passed).
• Ran a Playwright script to open the page and capture a screenshot (wood-style-optimized.png) for visual verification (screenshot produced).
