深色字看不清：先定配色
深色字配深色背景，远看不清。Codex 从海报设计师的角度定了方案：整张改用浅蓝绿底，普通话和粤语各出一版，并转成灰度检查对比度。
按下播放，看它一版版改出来。
关于那个海报啊，深色的字配偏深色的背景，其实远处看不太显眼，能调整一下？还有就是我想弄多一个粤语的新版本？还有就是第三讲的标题我们改了
我先找出当前海报版本和第三讲的新标题，确认哪些文字需要提高对比度，以及粤语版可以沿用哪些内容。

当前选稿是 A4 竖版的「纸条痛点 · 主讲人署名版」，仓库里也保留了一版旧粤语标语「AI，係你嘅對手，定係你對手？」。大纲和邀请文案中的第 3 讲目前都叫「只有一日记忆的员工」。
这版大部分文字已经画进图片，调整对比度和讲次标题需要改原画或重做文字层；我先把版本和文案范围确认清楚。

看过第三讲讲稿了，标题确实是「只有一日记忆的员工」，正文也围绕这位员工如何靠资料、方法和工作记录接续工作展开。原海报的第 3 讲已经用了这个标题，两张新版会按讲稿逐字核对。
我也看到了原图：问题主要在下半部，黑色大标语和活动信息直接压在蓝绿色纹理上。建议保留上半部纸条和人物，把下半部改成更均匀的深蓝绿底，主标语与信息用亮米白色，减少文字背后的纹理。后续原画局部修改会使用 imagegen 技能，再单独排入清晰的文字和二维码。
<proposed_plan>
海报对比度调整与粤语新版
以当前「纸条痛点 · 主讲人署名版」为底稿，制作两张 A4 竖版海报，保留纸条、人物和俯视构图。
画面与文案
- 上半部保持浅色纸条配深色文字；下半部改用均匀的深蓝绿色底，弱化纹理，主标语、课程名称及活动信息使用亮米白色。
- 主标语维持醒目的大字；适当加重活动时间、地点与主讲人文字，改善远看辨识度。
- 普通话版保留：「重复的事，让 AI 接手；难办的事，和 AI 联手。」
- 粤语版只替换主标语：「AI，係你嘅對手，定係你對手？」其余文字沿用正式中文，不增加「粤语授课」标识。
- 第 3 讲依据现有讲稿统一为「只有一日记忆的员工」。原画已使用此标题，制作时核对清晰度与完整性。
- 参与信息沿用现有文案：李庭辉、10 月 15 日 18:30–19:30、会议室 5，以及现有报名方式和课程主页。
制作与归档
- 使用 imagegen 局部清理原画中的下半部文字和纹理，再以独立文字层排入两版标语及参与信息；二维码继续使用真实 SVG。
- 两版共用修改后的插画，分别新增稳定 ID：
paper-speaker-contrast、paper-cantonese-contrast，保留原有历史版本。 - 更新海报索引，将普通话高对比版设为当前选稿，粤语版作为新增完整版本展示。
- 保存可重建脚本、冻结 HTML 和核验后的打印 PDF；预览 PNG 输出至构建目录。不修改讲稿，不提交或发布。
验收
- 并排比较原版和两张新版，检查缩小预览时主标语、课程名、时间和地点是否清楚。
- 逐字核对八讲标题、粤语用字和参与信息，检查遮挡、残留旧字及文字溢出。
- 确认 PDF 为单页 A4、字体正常、二维码可识别且指向课程主页。
- 运行海报构建与现有测试，验证两版展示、下载及历史版本入口。

嗯，从海报设计师的角度想清楚配色是否合理？
我会重新看整张海报的色彩层级，重点比较两种方案：把蓝绿底加深、文字提亮，或把文字所在区域换成浅纸色，保留黑色大字。两种做法都能提高对比度，但对原有纸张和印刷风格的影响不同。

从海报设计的角度看，原来的蓝绿、米黄、酒红组合是合理的，问题主要是文字落在哪里。蓝绿和米黄形成冷暖对比，酒红人物是视觉焦点；但下半部的黑字叠在有排线的蓝绿底上，文字和纹理会互相干扰。仅加粗，解决不了这个问题。
我更推荐调整之前的方案：保留蓝绿插画区，把下方标语与活动信息放到一块连续的浅米色纸面上，使用近黑色文字。 这能延续上半部「纸上写字」的视觉语言，也让读者更容易从插画转向邀请信息。主标语靠字号和留白突出，时间、地点靠字重突出，不再增加颜色。
建议控制在这四种颜色：
用途 颜色 标语、正文 近黑 #171C1C下方文字区 浅米白 #F5ECD6，纹理很淡插画背景 保留现有蓝绿 人物与少量强调 沿用酒红，不扩大面积 近黑字与浅米白底的理论对比度约 14.6:1。之前建议的深蓝绿底配亮米白字也能做到约 7.4:1，但下半部会更沉重，小字反白在打印时也更依赖印刷质量。对这张需要远看、又有不少参与信息的海报，我更倾向浅纸色文字区；最终仍需要按实际尺寸检查，色值不能代替打印效果。

Unifying canvas background
那就采用贯穿整张的浅蓝绿色底＋近黑色文字。这样保留原来的冷暖配色和纸条主题，也能提高远看辨识度。
之前提议把底色加深，会让整张海报更沉重；只把下半部换浅色，又会切断画面的连续性。更合适的是统一提亮蓝绿底，并压低纹理的存在感。米黄纸条与酒红人物继续提供层次。
<proposed_plan>
统一浅蓝绿底的双版本海报
配色与视觉层级
- 整张海报使用同一浅蓝绿底
#C7DDD8，贯穿插画区、主标语和底部信息，不设置上下分色背景或横向色块。 - 纸条保留暖米白
#F5ECD6，与偏冷的背景形成柔和区分；保留黑色轮廓和纸张重叠关系。 - 主标语、课程名称、主讲人及参与信息统一使用近黑
#171C1C。以字号、字重和留白区分层级。 - 保留人物的酒红及深色服饰，作为画面的视觉焦点，不扩大酒红面积。
- 蓝绿底的排线和颗粒明显减淡，文字背后的纹理尤其克制。局部调整背景，避免整体提亮导致人物和纸条褪色。
两版内容与制作
- 普通话版：「重复的事，让 AI 接手；难办的事，和 AI 联手。」
- 粤语版：「AI，係你嘅對手，定係你對手？」仅替换主标语，其余使用正式中文。
- 两版沿用当前构图、主讲人及活动信息；第 3 讲按讲稿核对为「只有一日记忆的员工」。
- 使用 imagegen 修改共享原画背景并清理下方旧字，再以独立文字层排入两版标语和参与信息，叠加真实 SVG 二维码。
- 保持 A4 竖版，新增
paper-speaker-contrast和paper-cantonese-contrast；普通话版设为当前选稿，原版保留归档。
验收与交付
- 并排检查原版与新版，以及缩小预览、灰度预览：主标语应最先被读到，课程名称、时间地点其次，插画仍清晰。
- 逐字核对八讲标题、粤语用字和参与信息，检查旧字残留、遮挡与溢出。
- 核验单页 A4 PDF、字体和二维码；提供打印 PDF、预览 PNG，并保留构建脚本及冻结 HTML。
- 运行海报构建和现有测试。屏幕预览通过后仍需实际尺寸打印校样，确认远看效果。
- 不修改讲稿，不执行提交或发布。
</proposed_plan>
- 整张海报使用同一浅蓝绿底
PLEASE IMPLEMENT THIS PLAN:
统一浅蓝绿底的双版本海报
配色与视觉层级
- 整张海报使用同一浅蓝绿底
#C7DDD8，贯穿插画区、主标语和底部信息，不设置上下分色背景或横向色块。 - 纸条保留暖米白
#F5ECD6，与偏冷的背景形成柔和区分；保留黑色轮廓和纸张重叠关系。 - 主标语、课程名称、主讲人及参与信息统一使用近黑
#171C1C。以字号、字重和留白区分层级。 - 保留人物的酒红及深色服饰，作为画面的视觉焦点，不扩大酒红面积。
- 蓝绿底的排线和颗粒明显减淡，文字背后的纹理尤其克制。局部调整背景，避免整体提亮导致人物和纸条褪色。
两版内容与制作
- 普通话版：「重复的事，让 AI 接手；难办的事，和 AI 联手。」
- 粤语版：「AI，係你嘅對手，定係你對手？」仅替换主标语，其余使用正式中文。
- 两版沿用当前构图、主讲人及活动信息；第 3 讲按讲稿核对为「只有一日记忆的员工」。
- 使用 imagegen 修改共享原画背景并清理下方旧字，再以独立文字层排入两版标语和参与信息，叠加真实 SVG 二维码。
- 保持 A4 竖版，新增
paper-speaker-contrast和paper-cantonese-contrast；普通话版设为当前选稿，原版保留归档。
验收与交付
- 并排检查原版与新版，以及缩小预览、灰度预览：主标语应最先被读到，课程名称、时间地点其次，插画仍清晰。
- 逐字核对八讲标题、粤语用字和参与信息，检查旧字残留、遮挡与溢出。
- 核验单页 A4 PDF、字体和二维码；提供打印 PDF、预览 PNG，并保留构建脚本及冻结 HTML。
- 运行海报构建和现有测试。屏幕预览通过后仍需实际尺寸打印校样，确认远看效果。
- 不修改讲稿，不执行提交或发布。
- 整张海报使用同一浅蓝绿底
我会按确认的配色制作两版：先修改共用插画，再排入独立文字和二维码，最后检查打印文件与海报页面。

Preparing archive and index
两版初稿已导出。浅蓝绿底现在贯穿整张，原来的粗排线明显减淡，米白纸条和酒红人物仍有层次；下方黑字也更容易辨认。
我已核对八张纸条，第三讲标题仍是「只有一日记忆的员工」。接下来检查灰度效果、字体嵌入和二维码，并更新海报索引。
