时光海苔是一款把“信息→载体→未来”串联起来的工具。你可以将一段文字、一个心愿或某个秘密，封存进图片、二维码或NFC标签中，辅以加密与时间设定，让它在某个不经意的时间点被再次想起、被再次读到。就像投向海里的漂流瓶，信息在时光与偶然中流动，被未来的你或陌生人发现。 主要功能： - 图片时间胶囊：把文字隐写进图片中，设定解锁时间或密码 - 二维码时间胶囊：将信息生成带时间/密钥的二维码 - NFC时间胶囊：把数据写入NFC标签，配合时间与密钥开启 - 漂流瓶模式：使用默认密码或开放密钥，让偶遇的人也能解锁 - 私密模式：自定义密码，仅信息持有者可解密 安全与隐私： - 本地处理：所有加解密均在本地完成，不上传到服务器 - 可控权限：仅在需要时请求相机/相册/NFC等权限 - 透明可控：你决定信息何时、向谁、以何种介质出现 适用场景： - 把给未来的信写进今天的图片里 - 与朋友之间的“时间约定”与纪念日 - 课堂/活动中的“盲投漂流瓶”互动 - 作品、展览中的叙事与彩蛋 “通过各介质的存储，辅以加密和时间判断，让数据通过双盲运送到未来。” 当你再次解锁那枚时间胶囊，读到的是过往的自己，也是此刻的真实。
