fix(mobile): 481–519px 中间带的卡片与属性网格溢出 by modusensus · Pull Request #543 · slow-stack/mneme

modusensus · 2026-11-01T23:22:48Z

问题

#542 给面板加了 320–480px 的移动端断点，防溢出的关键写法是把 minmax(252px,1fr) 换成 minmax(min(252px,100%),1fr)。但那两条只写在 @container (max-width:480px) 里，基础规则仍是裸 minmax(252px,1fr)（.mneme-cards）与裸 minmax(200px,1fr)（.mneme-attrgrid）。

于是一段两不管的中间带出现了：481–519px。它在 480 断点之外（左栏回到 216px 横向排列），两栏又排不下——卡片轨道仍被要求 252px，横向溢出 2–11px，被外层 overflow:hidden 直接切掉（不是滚动条，是切掉看不见）。

用真实 CSS 在 Edge 156 headless 里按宽度逐一渲染（320/360/390/430/460/480/481/490/500/510/519/520/540/560/640/900 × 记忆页/实体页，共 32 页）实测：

宽度	修复前	修复后
记忆页 481 / 490 / 500 / 510	各 1–2 条 `SCROLLX`（`.mneme-cards` 300 > 可用 265）	ovf=0，卡片宽 217 / 226 / 236 / 246
实体页 detail 481–519	257–276px 而属性网格仍要 200px	209–247px 单列，不溢出
320 / 360 / 390 / 430 / 460 / 480 / 519 / 520 / 540 / 560 / 640 / 900	ovf=0	ovf=0（未回归）

改了什么

兜底上移到基础规则（真正的修复）。min(252px,100%) 的正确作用域本来就是「所有宽度」，481–519px 只是其中最窄的一段，写在断点里等于给中间带留缺口。480 档里的重复声明一并删掉（已上移，留着只是死代码）。
回归测试换锁定位置。原来两条 body.includes("minmax(min(252px,100%),1fr)") 锚在 480 档 body 上，兜底一上移就会假红。改成新增 topLevel 切片器：遍历 CSS 块，遇到 @ 就按括号配对跳过并整块丢弃，只留顶层规则；再断言切片长度 > 10000 防止切片器自己坏掉导致假绿。锁两件事——两处基础 minmax(min(…,100%),1fr)。

本 PR 不做什么

不碰图谱的 touch-action。 过程中曾把它从 none 改成 pan-y（理由是图谱的拖拽只挂 mousedown/mousemove/wheel，全仓 onPointerDown/onTouchStart 命中 0），评审指出这套论证反过来也成立：pan-y 会把纵向手势交给浏览器，而图谱收到的仍是鼠标事件，浏览器在 none 下是否派发兼容鼠标事件、兼容事件能否撑起纵向拖拽，没有真机无法定论。已全部回退，基础规则与 480 档的 pan-y 都与 main 一字不差。真要两者兼得，得把图谱改成 Pointer Events 并自己接管手势，那是另一个改动。

另有一处刻意的取舍：我一度给基础规则加 max-height:min(440px,52vh)，想把 481–519px 那段 440px 高的图谱压下来。实测确实压到 353px——但 52vh 在常见窗口高度（≈680px）下对桌面也生效，900px 宽的桌面同样被压成 353px，等于顺手改了大屏观感。已回退；代价是 481–519px 中间带的图谱仍是 440px 高，这个问题刻意不修。

验证

变异自证：把基础 minmax(min(252px,100%),1fr) 退回裸 minmax(252px,1fr) → 红。恢复后 85/85。
node --check lib/client.js 通过；check-sync → src/ 与 lib/ 一致（82 个文件）（client.js 是 lib-only 文件，不在比对集合内）；test/contrast.test.js 5/5（本次未在 @container / @media 内写任何颜色）。
全量 npm test：2609 tests / 2608 pass / 0 fail / 1 skipped（skipped 是既有那条）。

已知未覆盖

仍是没有真机：adb devices 为空，需要设备接上并重启宿主让插件重新探测 adb。所有宽度结论来自 Edge headless + 真实 CSS 的静态测量；交互层面（拖拽、滚动链、软键盘顶起、单指缩放）未经真机验证。

480 主断点之上、两栏又排不下的一段宽度（481–519px）落回基础规则，而 minmax(min(252px,100%),1fr) 此前只写在断点里，基础规则仍是裸 minmax(252px,1fr)。结果是卡片轨道仍要求 252px、横向溢出 2–11px 被外层 overflow:hidden 切掉；实体页属性网格同理。 - 两处 100% 轨道下限上移到基础规则（它的作用域本来就是所有宽度）， 480 档里的重复声明删掉 - .mneme-graphsvg 的 touch-action 由 none 改 pan-y：图谱没有触屏手势实现，none 只让手指在图上竖划时页面滚不动 - 回归测试改锁「剥掉嵌套块后的顶层规则」，新增 topLevel 切片器实测（Edge headless + 真实 CSS，320–900px 共 24 个页面）：修复前 481/490/500/510 各有 1–2 条横向溢出，修复后全部为 0。

🔵 Needs a closer look

Because the touch-action change affects mobile scroll and gesture arbitration, approval should wait for human validation of vertical scrolling, graph interaction, and nested scroll behavior on a representative touch device.

No open issues 🎉

What changed in this PR

This pull request fixes responsive layout overflow in the 481–519px width range and restores vertical touch scrolling over the graph without changing desktop graph sizing.

Changes:

Moves width-safe minmax() safeguards into the base card and attribute-grid rules.
Changes graph touch-action from none to pan-y.
Updates regression tests to verify the base CSS declarations and documents the changes in the changelog.

Review findings:

Moderate: The cssBlock scanner can mistake @ characters in selectors, comments, or strings for at-rules, potentially skipping unrelated top-level rules and allowing placement checks to pass incorrectly.
Moderate: The topLevel assertion does not protect the nested 480px graph rule; changing that rule back to touch-action: none could leave the test green while reintroducing the mobile scrolling issue.

File	Summary
`dsh-mneme/test/client.test.js`	Adds top-level CSS checks for the intermediate-width grid fixes and graph touch behavior.
`dsh-mneme/lib/client.js`	Applies width-safe grid tracks globally and enables vertical graph touch scrolling.
`dsh-mneme/CHANGELOG.md`	Documents the overflow issue, touch-scrolling change, trade-offs, and validation results.

#543 里把 .mneme-graphsvg 的 touch-action 从 none 改成 pan-y，理由是全仓 onPointerDown/onTouchStart 命中 0、图谱的拖拽只挂 mousedown/mousemove/wheel，触屏上没有自定义手势可抢，留 none 只会让手指在图上竖划时页面滚不动。评审指出反过来也成立：pan-y 会把纵向手势交给浏览器做页面平移，而图谱的拖拽只有鼠标事件实现——触屏纵向拖拽到底走哪条路，取决于浏览器在 touch-action:none 下是否派发兼容鼠标事件，没有真机无法定论。这一版不做无法复验的行为变更。 - lib/client.js 基础规则回到 touch-action:none，注释改写成保留理由 - 480 档里 #542 引入的 touch-action:pan-y 一并收回（限高 max-height 保留） - 回归锁翻转：基础规则必须是 none，顶层规则不得出现 pan-y - CHANGELOG 对应段落改写成回退后的结论，保留为什么没做这个改动复验：Edge 156 headless 静态测量 320–900px 共 32 页，卡片与属性网格零溢出；图谱高度 ≤480 为 320px（480 档 max-height 生效）、≥481 为 440px（内联高度）； touch-action 全段 none。npm test 2609 / 2608 pass / 0 fail / 1 skipped。

上一版把基础规则的 touch-action 从 none 改成 pan-y，评审两轮指出同一个问题：这一版既没有真机验证触屏拖拽路径，又顺手删掉了 480 档原有的 pan-y，等于在没有依据的情况下改了两处行为。现在按最小改动收敛： - 基础规则 .mneme-graphsvg 保持 touch-action:none（与 main 一致），只留一段注释说明为什么不在这一版动它 - 480 档的 touch-action:pan-y 恢复成 main 的样子，本 PR 不再涉及 - 回归锁只留两处基础 minmax(min(…,100%),1fr)，不再锁 touch-action - CHANGELOG 里那段 touch-action 的论证整段删除本 PR 的实际范围回到一件事：卡片网格与属性网格的 100% 轨道下限从断点内移到基础规则，补上 481–519px 这段中间带。复验：Edge 156 headless 静态测量 320–900px 共 32 页零溢出；npm test 2609 / 2608 pass / 0 fail / 1 skipped。
