/* Tagbay Suites Melaka —— 全站唯一的样式表，手机优先。
 *
 * 配色（屋主指定，2026-10-16）：
 *   深青 #1D6A73 · 青 #328C8C · 橙 #F29849 · 沙 #F2E4D8 · 珊瑚 #F28157
 *
 * 对比度（WCAG，小字要 4.5:1）—— 改颜色前先算：
 *   白字 on 深青 #1D6A73            6.2:1  ✓
 *   沙色字 on 深青                   5.0:1  ✓
 *   墨色 #0B2E33 on 橙 #F29849       6.4:1  ✓（主按钮）
 *   墨色 on 珊瑚 #F28157             5.5:1  ✓（「已售完」标签）
 *   墨色 on 沙 #F2E4D8              11.6:1  ✓
 *   次要字 #4A6466 on 沙／白         5.1 / 6.4:1 ✓
 *   珊瑚字 #A44A28 on 白／浅沙       5.9 / 5.4:1 ✓（浅底上的强调字）
 *   浅橙 #F7B37A on 深青             3.5:1  只准用在大标题（≥24px）
 *   ✗ 白字 on 青 #328C8C 只有 4.0:1、白字 on 橙／珊瑚 2.2–2.6:1 —— 这几个底色上一律用墨色字。
 *   青 #328C8C 只当装饰（线条、图示、边框）。
