 * Sefton Home — style.css
 * -----------------------------------------------------------------------------
 * 设计令牌（:root）已逐个核算对比度，全部满足 WCAG AA 小字 4.5:1
 * （WCAG 2.x 相对亮度公式；半透明文字按 sRGB 直接合成后再算）：
 *   --ink   #262220  on --bg #faf8f5 = 14.87   on --surface #ffffff = 15.76
 *   --text  #57504a  on --bg         =  7.47   on --surface          =  7.92
 *   --muted #6b6058  on --bg         =  5.76   on --surface          =  6.11
 *   --brand #5b3a29  on --bg         =  9.51   白字 on --brand        = 10.09
 *   --sale  #b04f5c  on --bg         =  4.81   白字 on --sale         =  5.10
 * 注意：--surface-2 只作图片占位底色，其上不落任何文字（--sale on --surface-2 仅 4.31）。
 * 圆角作用域：交互元素（按钮/徽标/筛选标签/输入框）给圆角；图片与 logo 框保持直角。
 *
 * ⚠️ 主色是**暖棕**（胡桃色系，色相约 24°），全站色调**不含绿色** —— 这是明确的客户要求，
 *    不是随手挑的。所以别把 --brand 改回墨绿 / 橄榄 / 鼠尾草 / 灰绿一类的色相；要调深浅也
 *    只在暖色相里调，且**改完必须重算上面那张表**（--brand-dk 算白字、--brand-soft 算
 *    --brand 落在它上面的对比度）。
 *    同一份色值还长在别处，改色时要一起改：8 个页面的 <meta name="theme-color">、
 *    assets/js/layout.js 里两处内联 SVG 的 fill、tools/build_favicon.py 的 FALLBACK_BRAND，
 *    以及由它生成、读本文件 --brand 的图标三件套（重跑脚本即可）。
