Every non-deck, non-web scene now holds ten templates: cards (spec themes as living samples), infographics, tutorials, comparisons and carousels (nine spec themes with per-set master-board rules), plus two web landings whose 'generate from this' pins their measured style guides — a basis the document swap used to drop before the turn ever saw it. All fifty-eight ship generator-reproduced (sha256- matched), audit-clean, with baked preview cards, and the scene tab row pins Slides second-from-last and Web last. Two prompt-center entries carry the web pair with re-rendered previews and honest render provenance. Claude-Session: https://claude.ai/code/session_01FqKQqNj8exYwopGDpYUU7x

"""event-poster-deck.op — 活动策划 deck · 公告海报（16:9 六页）
|
||
|
||
既有的五套 deck 全是「工作场合」：商务汇报（slide-deck）、融资路演
|
||
（pitch-deck-dark）、课堂讲义（lecture-deck-light）、发布会主题演讲
|
||
（minimal-keynote）、开发者产品发布（gradient-tech）。平民线缺的是**生活
|
||
场合**的那一套 —— 市集、社团活动、公司团建、开业招商，做的人不是产品经理
|
||
而是主办方，要交代的是「什么时候、在哪儿、有什么、怎么来、多少钱」。
|
||
|
||
所以这套 deck 的结构和商务 deck 是两回事：没有目录页、没有数据页、没有趋
|
||
势图，六页分别是 封面 / 亮点 / 日程 / 场地交通 / 票种 / 结尾，每一页都对应
|
||
主办方真的要回答的一个问题。
|
||
|
||
视觉语言取「包豪斯公告海报」——**展览与集市公告海报本来就是这套语言的原
|
||
生用途**：近白展墙底、决断的红蓝色块、零圆角、顶天立地的粗黑标题、色块本
|
||
身就是版式结构。对齐 style-guide `bauhaus-geometric-light`，这也是这张模
|
||
板卡上「基于此模板生成」按钮真正会复现的东西。
|
||
|
||
和 minimal-keynote 的白底不是一回事：那套整本靠留白与细线做层级，没有一块
|
||
饱和色；这套靠**大色块**做层级，白只是色块之间的展墙。
|
||
|
||
### 配色推导（采样 → 收敛 → 论证）
|
||
|
||
第一版用的是紫→品红渐变。推翻了：小红书视觉体系把「廉价蓝紫渐变」列在禁
|
||
止项第一条，风格库的默认审美禁区也点名「激进紫渐变万能公式」。那不是配色，
|
||
是模型先验里抽签抽到的那几个网红色。
|
||
|
||
- **采样**：内容自带的色彩记忆 —— 露天市集的遮阳棚红白条纹，与老码头的
|
||
铁件蓝。两个都从「城市周末市集 · 老码头广场」这个内容里来，不是发明的。
|
||
- **收敛**：oklch 压到 2 个有彩色 + 1 组中性明度序列。棚布红
|
||
oklch(0.52 0.15 32)，码头铁蓝 oklch(0.42 0.11 250)，色相角相差 218°；
|
||
中性走 L 0.17 / 0.40 / 0.68 / 0.92 / 0.975 一条明度序列。
|
||
- **论证**：chroma 压在 0.11-0.15 —— 那是油墨印在纸上的饱和度上限，屏幕
|
||
RGB 冲到 0.25 以上就是塑料感。这两个色是「印出来的海报」，不是「屏幕上
|
||
的按钮」。
|
||
|
||
### 负约束（本模板明令不做的事）
|
||
|
||
- 不用任何渐变。六页零 `linear_gradient` / `radial_gradient`。
|
||
- 不用圆角。`cornerRadius` 全篇为 0 —— 包豪斯的几何精度里没有圆角软化，
|
||
药丸形状（`cornerRadius: 999`）尤其禁止。
|
||
- 不用阴影。层级由色块与留白给，不由 `effects` 给。
|
||
- 不用光晕装饰。装饰只能是**实心几何形**（正圆、粗条），它们参与构图，
|
||
不是背景氛围。
|
||
- 不用第三个有彩色。红与蓝之外只有中性明度序列。
|
||
- 不写 AI 套话（「赋能 / 无缝 / 一站式 / 打造闭环」），文案只写主办方真会
|
||
说的话。
|
||
- 不用 emoji 当图标。
|
||
|
||
排版遵循 skills/domains/slides.md 与中文排印规范：
|
||
- 每帧 1920×1080，内容距边缘 ≥100px（这里 120）
|
||
- 正文 ≥24（取 27-32），标题 ≥40，展示字 100+
|
||
- **CJK 行高比西文全线高 0.2**：页标题 1.2，小节标题 1.3，正文 1.7；
|
||
封面与结尾的巨字（132/148px）收到 1.12，仍在 CJK 展示字的 1.1-1.2 区间内
|
||
- **CJK 负字距不超过 -0.02em**（汉字是满格设计，再负就笔画相撞）；
|
||
只有西文数字沿用西文的 display 收紧
|
||
- 汉字走 Noto Sans SC，数字与拉丁走 Inter —— 等价于中文排印规范里
|
||
「西文在前、中文在后」的 fallback 链，只是在 .op 里按节点写死
|
||
|
||
白底与红底上的对比度（WCAG，实测见文件末尾）最低一对是 4.76:1。
