Description: 为杭州折之环保科技有限公司定制的中文企业主题,核心识别是「折纸折痕光影」:暖纸白(#f2eee4)与浅米(#e9e3d5)铺底,叠一层极淡纸张纤维纹;折面明暗用一组同源暖灰阶(高光面 #efe8da / 中间面 #d6cbb6 / 背光面 #b3a68c / 深折 #8a7c62)塑出立体折叠,墨(#33302a)写正文,单一柿橙(#d9663d)只点在 CTA、链接、关键数字与纸鹤点睛处。区块之间以「折痕」分隔(上浅下深的 1px 双线),区块底由几块大折面拼成,折缝处一道高光线;卡片是「一张折起的纸」(切角折页 + 折角背面深一阶 + 右下折痕);首屏是一座由折面拼出的折纸喷淋塔,塔顶停一只小纸鹤;按钮像折起的纸标签,一角翻折。工艺做成「七折成塔」的折叠步骤,案例做成可展开的「折页」。安静、精巧,有纸的温度与折叠的秩序。演示用虚构主题,零外链,纯 CSS 与内联 SVG。
