/**
 * SituBoard Theme System
 *
 * Provides two modern themes via CSS custom properties:
 * - Dark Modern (default): Deep dark backgrounds with blue accents
 * - Light Modern: Clean light backgrounds with blue accents
 *
 * Theme is stored in localStorage and applied via data-theme attribute on <html>
 *
 * Shape language: sharp professional corners (2px hair radius) — not Bootstrap pills.
 * Board content themes (ship/port grids) keep their own rules in main.css / port.css.
