核对日期：2026-09-29。运行版使用本地资源，不依赖素材热链或字体 CDN。
| 素材名称 | 类型 / 作者 | 原始来源 / URL | License / 是否要求 attribution | 实际用途 |
| --- | --- | --- | --- | --- |
| Cormorant Garamond | 字体；Christian Thalmann / Catharsis Fonts | [Google Fonts 官方目录](https://github.com/google/fonts/tree/main/ofl/cormorantgaramond)；[原始可变 TTF](https://raw.githubusercontent.com/google/fonts/main/ofl/cormorantgaramond/CormorantGaramond%5Bwght%5D.ttf) | SIL OFL 1.1。随副本保留版权与许可，不要求画面署名。全文 `licenses/CormorantGaramond-OFL.txt` | 550 字重 lining figures 导出主钟与秒数轮廓；500 字重 lining 子集用于日历，400 子集用于少量拉丁文本。修改字体分别重命名 Four Seasons Numerals / Four Seasons Roman。 |
| Noto Serif CJK SC Regular | 字体；Adobe / Noto 项目，完整版权保存在字体与许可中 | [官方仓库](https://github.com/notofonts/noto-cjk)；[原始 OTF](https://raw.githubusercontent.com/notofonts/noto-cjk/main/Serif/OTF/SimplifiedChinese/NotoSerifCJKsc-Regular.otf) | SIL OFL 1.1。保留版权与许可，不要求画面署名。全文 `licenses/NotoSerifCJK-OFL.txt` | 中文标题轮廓与本地中文子集，修改名称 Four Seasons Text。小记中的未收录字符由系统字体补齐。 |
| Yuji Syuku | 书法字体；Yuji Kataoka / Kinuta Font Factory | [Google Fonts 官方目录](https://github.com/google/fonts/tree/main/ofl/yujisyuku)；[原始 TTF](https://raw.githubusercontent.com/google/fonts/main/ofl/yujisyuku/YujiSyuku-Regular.ttf)；[OFL 原文](https://raw.githubusercontent.com/google/fonts/main/ofl/yujisyuku/OFL.txt) | SIL OFL 1.1。副本保留版权及许可，不要求画面署名。全文 `licenses/YujiSyuku-OFL.txt` | 仅用于拾光册题名。子集 WOFF2 重命名 Four Seasons Brush；不请求 Google 字体 CDN。 |
| 四季导航书法 alpha 图 | 透明 PNG；用户提供 | `assets/ChatGPT 图像 2026年9月29日 01_09_21.png`（本地保留的用户原文件） | 用户提供的作品素材；未附独立开源许可。本项目不将其标为 CC0、OFL 或其他第三方许可。 | 原 PNG 字节不变；导航 SVG 用 alpha mask 和裁切路径显示原字形，并按当前前景色着色。 |
| Rain (1).ogg | 自然雨声实录；ezwa | [Commons 文件与许可页](https://commons.wikimedia.org/wiki/File:Rain_%281%29.ogg)；[下载 Ogg](https://upload.wikimedia.org/wikipedia/commons/0/0e/Rain_%281%29.ogg)；页面记录原始来源 [PDSounds 682](http://www.pdsounds.org/sounds/rain) | Public Domain，作者向全球公有领域发布；不是 CC0。页面声明可无条件使用，不要求署名；此处保留作者与来源。PDSounds 老地址不作为运行依赖。 | `assets/audio/rain.mp3`，唯一环境音。约 45 秒原录音中取 0–42 秒，用首尾各 7 秒做等功率交叉淡化，得到约 35 秒循环；响度 -20 LUFS / 峰值目标 -3 dB、44.1 kHz、128 kbps MP3。用户手势后加载，默认关闭。 |
字体源下载的 SHA-256 与大小见 `licenses/font-sources.json`。字体及导出的有限轮廓继续遵循 OFL，不把字体许可扩展到整件作品。原有鸟声、风声录音已从当前源码资产与运行清单移除，历史版本仍可由 Git 查阅。没有合成铃声、chirp、purr、电子空气或声音提示。
## 用户提供的核心资产
四张 `assets/*-original.png`、subject / aperture / apertureNight、grain、bell-sprite / bell-patch 来自用户交接包。四张原 PNG 是 source of truth，每次构建核对固定 SHA-256，未覆盖、整体重绘或替换人物。主体色彩直接采样原图，使用本轮 image_gen 从原 PNG 重新提取的 alpha matte，并在画幅截断处羽化；不用旧主体抠图的 alpha；桌面直接读取原 PNG，手机尺寸衍生和主体均使用无损 WebP。源哈希见 `ASSET_MANIFEST.json` 与 `scripts/verify-assets.mjs`。
这些材料按本次用户授权用于本作品；不额外宣称获得独立素材再分发许可。
## 本次工具生成的辅助物件
`assets/relics/season-specimens-source.png` 由本次会话的 OpenAI 内置 `image_gen` 生成，参考用户提供的夏季原图画风，内容只包含蒲公英、玻璃铃、银杏、冰晶，没有人物。四份透明 WebP 从该图集按象限无损裁边后导出。
- 文件：`assets/relics/spring.webp`、`summer.webp`、`autumn.webp`、`winter.webp`。
- 用途：拾光册中的收藏物、日历页角的季节物件；秋季银杏也作为可接住的粒子。**四季分钟装置不使用这些位图。**
- 来源类型：本项目工具生成输出，不是外部下载的第三方素材，不擅自标成 CC0 或 OFL。生成平台的适用条款继续适用。
- 生成记录、完整提示词、参考图与导出方式见 `GENERATED_ASSETS.md`。源图集随源码包保留，不进入 Web 首屏。
## 本轮四张主体 alpha
`assets/mattes/{spring,summer,autumn,winter}-extracted.png` 是 OpenAI 内置 `image_gen` 分别参考本项目四张原 PNG 的透明背景输出，生成日期 2026-09-28 / 29。它们只提供 alpha 边界，RGB 不进入最终人物；`scripts/prepare-subjects.mjs` 将经过低透明残留清理的 alpha 与原图 RGB 合成 `assets/{spring,summer,autumn,winter}-subject-clean.webp`。无外部作者、来源 URL 或第三方 attribution 要求；工具输出不标注为 CC0 / OFL，适用生成平台条款。
完整提示词、原始输入、工具输出路径、参数及用途见 `assets/mattes/GENERATION.md`，源文件随源码包保留，未进入首屏。四张原 PNG 的哈希完全不变。
## 本地化与再现
普通生产构建无需联网、Python、FFmpeg 或 API Token。运行所需字体、图像与雨声按内容哈希随 `dist/assets/` 分发；单 HTML 收藏版内联同一资产。许可和来源文本嵌入两种产物的素材说明，OFL 全文也随 Web 构建分发。
`scripts/prepare-fonts.py` 是可选维护工具，使用 fontTools + Brotli；普通 Node 构建直接采用已导出的字体。字体缓存路径为 `.cache/sources/cormorant.ttf` 、`.cache/sources/noto-serif-cjk-sc.otf` 与 `.cache/sources/YujiSyuku-Regular.ttf`。重新下载需对照已记录的哈希。
雨声使用真实录音，已验证解码、信号和生命周期；自动检查不等同于人的长时间听感判断。没有把程序合成噪声冒充环境实录。
## 冬季分钟的形体参考
用户在本轮提供 `ChatGPT 图像 2026年9月29日 02_03_23.png` 作为雪花形体参考。`scripts/prepare-snow-crystal.py` 用六臂连续 Bezier 曲线重新构造中央留白、凹弧和晶梢；该参考位图不进入运行资产，未重新生成一张雪花图片，也不宣称参考图具有开放素材许可。
## 2026-09-29 连续性修订
本次未引入新的第三方资产，也未再次生成人物。运行时 foreground 复用现有主体 alpha、原图 RGB 和统一构图矩阵；加强内部遮挡覆盖度不修改原文件。秋季银杏是项目内绘制的 SVG 曲线，春季种子是本地矢量线稿。
