feat(web-demo): 新增可收合與可拖曳調整的控制欄版面 - #15
Conversation
Browser Lab 左側控制欄固定為 380px 且無法收合，使用者在小螢幕或需要 更大預覽空間時無法自行調整版面。本次新增圖示切換鈕與可拖曳分隔線， 並將版面狀態保存於 localStorage，重新載入後可完整還原。 實作內容： - 在預覽面板標題列左側新增面板圖示切換鈕，可收合或展開左側控制欄。 - 於控制欄與預覽面板之間新增 role="separator" 分隔線，可用滑鼠拖曳調整寬度。 - 分隔線支援雙擊還原預設 380px，以及鍵盤 ArrowLeft／ArrowRight／Home／End 調整。 - 寬度限制在 260px 至 720px，且不超過工作區寬度的 60%，確保預覽面板保有可用寬度。 - 以 miniexcel.browser-lab.layout/v1 鍵保存寬度與收合狀態，載入時還原並依目前視窗夾限。 - 收合以 hidden 屬性搭配網格樣式實作；900px 以下的堆疊版面隱藏分隔線並維持單欄滿版。 - 拖曳期間於 body 加入 is-resizing 狀態，避免選取文字並維持 col-resize 游標。 - localStorage 無法使用或內容無效時回退為展開的預設版面，不影響既有操作。 影響範圍： - web-demo/public/index.html：新增控制欄切換鈕、分隔線與工作區 id。 - web-demo/public/styles.css：新增三欄網格、分隔線、切換鈕與收合狀態樣式。 - web-demo/public/app.js：新增版面狀態、localStorage 存取、拖曳與鍵盤調整邏輯。 - web-demo/tests/browser.spec.mjs：新增桌面版切換、拖曳、鍵盤、無效儲存值回退與行動版無溢位測試。 - docs/compatibility.md、docs/compatibility.zh-CN.md：更新 Browser Lab Playwright 覆蓋範圍說明。 驗證項目： - npm ci：通過。 - npm run build：通過。 - npm run test:e2e：28 項通過、20 項依既有桌面／行動版篩選條件跳過。 - 版面量測：1280px、901px、412px、320px 皆無橫向溢位；收合後預覽面板佔滿工作區。 - 主控台檢查：拖曳、鍵盤調整、切換與重新載入皆沒有警告或錯誤。

In `@web-demo/public/app.js`:
- Around line 159-163: Update readStoredLayout to validate the complete stored
layout record before restoring any fields: require a finite width within 260–720
and collapsed to be a boolean; otherwise return the expanded default layout with
width 380. Preserve both stored values only when the entire record is valid, so
initLayout does not restore partially invalid data.

- The resize width is computed from the rail's left edge, so the splitter's 14px track is included in the result. Grabbing the center and moving by only 1px changes a 380px rail to about 388px, and grabbing another point produces a different offset; track the pointer-down position and starting rail width and apply only the pointer delta.
elements.railSplitter.addEventListener("pointermove", (event) => {
if (activePointer === null || event.pointerId !== activePointer) return;
const left = elements.controlRail.getBoundingClientRect().left;
setRailWidth(event.clientX - left, { persist: false });
web-demo/public/app.js:250
- The new keyboard handler has four distinct key paths, but the regression test exercises only
ArrowLeft. Add focused assertions forArrowRight,Home, andEnd(including their clamping and persistence) so the keyboard acceptance paths cannot regress independently.
const next = {
ArrowLeft: current - RAIL_KEYBOARD_STEP,
ArrowRight: current + RAIL_KEYBOARD_STEP,
Home: min,
End: max,

已修正，commit dcdad1f。
有效意見：Number.isFinite(parsed?.width) 加上 parsed?.collapsed === true 只做單欄位檢查，因此 { "width": 0, "collapsed": true } 會被接受並以 260px 呈現且維持收合，width 超出範圍也只由 CSS/applyRailWidth 夾限，並未回退到規定的展開 380px 預設。
修正方式（web-demo/public/app.js:154-167）：先驗證形狀再決定是否還原任何欄位——非單純物件（null、陣列）、width 非有限數值或不在 260–720、collapsed 非 boolean 時，一律回傳 { width: 380, collapsed: false }；只有整筆記錄合法才同時套用兩個欄位。
驗證：新增 9 組無效資料的回歸測試（含 {width:0,collapsed:true}、{width:900,collapsed:true}、{width:null}、collapsed:"yes"、缺欄位、陣列與字串），確認控制欄可見、aria-expanded="true"、寬度 380px，且後續持久化的內容為 { width: 380, ... }。暫時還原修正時測試於 { "width": 0, "collapsed": true } 失敗，確認可攔阻。npm run test:e2e 29 項通過。

已修正，commit dcdad1f。
有效意見：body.is-resizing { cursor: col-resize; user-select: none; } 的宣告會被後代元素自身較明確的規則蓋過（例如 .segment、.button、.icon-button、.tab 的 cursor: pointer）。由於拖曳期間游標樣式取決於指標下的元素，滑過控制欄按鈕時會顯示 pointer，選取行為也可能被後代宣告還原。
修正方式（web-demo/public/styles.css:277-281）：改為 body.is-resizing, body.is-resizing * 同時套用 cursor: col-resize !important 與 user-select: none !important，確保整個拖曳期間（含 pointer capture 移動到其他元素上）維持調整游標與禁止選取。
驗證：新增 splitter drag keeps the resize cursor over interactive descendants 測試，實際按下分隔線並拖曳後檢查：body 具備 is-resizing、body 與 cursor: pointer 的 #rowsModeButton 之 computed cursor 皆為 col-resize、user-select 皆為 none、指標位置的 elementFromPoint 亦為 col-resize，放開後子元素恢復 pointer、分隔線維持 col-resize。暫時還原修正時測試在子元素斷言失敗，確認可攔阻。npm run test:e2e 29 項通過。
PR mini-software#15 的自動化審查指出兩個問題：readStoredLayout 逐欄位寬鬆驗證，資料 半殘時仍會套用無效欄位；拖曳期間的 is-resizing 只設在 body，子元素自身的 cursor: pointer 會蓋掉 col-resize。兩者皆已修正並補上可重現的回歸測試。 修正內容： - readStoredLayout 改為整筆記錄驗證：非物件、陣列、寬度非有限數值或超出 260px～720px、collapsed 非 boolean 時，一律回退為展開的 380px 預設版面。 - 無效資料不再只靠渲染階段夾限，避免以 260px 或維持收合的狀態殘留。 - is-resizing 狀態改為同時套用到 body 與其所有子元素，並以 !important 蓋過 按鈕等元素既有的 cursor: pointer，拖曳期間一律維持 col-resize 並禁止選取文字。 - 測試新增 9 種無效儲存值（型別錯誤、0、900、null、缺欄位、陣列、字串）的 回退驗證，並確認回退後的 380px 會正確寫回儲存內容。 - 測試新增拖曳游標契約驗證：body 與 cursor: pointer 子元素的 computed cursor 皆為 col-resize、user-select 為 none，指標放開後恢復原本的 pointer。 影響範圍： - web-demo/public/app.js：readStoredLayout 改為整筆記錄驗證。 - web-demo/public/styles.css：is-resizing 游標與選取規則一併套用到子元素。 - web-demo/tests/browser.spec.mjs：擴充無效版面回退測試並新增游標契約測試。 - docs/compatibility.md、docs/compatibility.zh-CN.md：更新為會校驗保存布局。 驗證項目： - npm run build：通過（miniexcel-wasm release 建置）。 - npm run test:e2e：29 項通過、22 項依既有桌面／行動版篩選條件跳過。 - 回歸驗證：暫時還原 app.js 修正時，「invalid stored layouts」測試在 {width: 0, collapsed: true} 案例失敗；暫時還原 styles.css 修正時， 「resize cursor」測試在子元素游標斷言失敗，確認兩項測試都能攔阻原始缺陷。
摘要
讓 Browser Lab 的版面可以自行調整：新增圖示切換鈕收合／展開左側控制欄，並在控制欄與預覽面板之間加入可拖曳的分隔線；切換狀態與寬度都會寫入
localStorage，重新載入後還原。Closes #14
背景
控制欄原本固定為
380px，與預覽面板之間只有固定間距，無法收合、無法調整，也無法記憶使用者的版面偏好。需要更大預覽空間（寬表格、JSON／Markdown 輸出）或需要更寬控制欄（Analyze 條件與彙總編輯列）時都必須手動縮放瀏覽器。實作內容
#railToggleButton），以aria-expanded反映狀態、aria-controls指向控制欄，並以title提示下一個動作。role="separator"、aria-orientation="vertical"、可聚焦的分隔線（#railSplitter），提供aria-valuemin／aria-valuemax／aria-valuenow。body.is-resizing狀態，游標移出分隔線仍可持續調整，過程中不選取文字並維持col-resize游標。380px；鍵盤ArrowLeft／ArrowRight以 16px 調整，Home／End跳到最小／最大寬度。260px～720px，且不超過工作區寬度的 60%，確保預覽面板保有可用寬度；視窗變更大小時重新套用夾限。miniexcel.browser-lab.layout/v1保存{ width, collapsed }；載入時還原，儲存值無效或localStorage不可用時回退為展開、380px。hidden屬性加.workspace.is-collapsed網格樣式實作；900px以下的堆疊版面隱藏分隔線並維持單欄滿版。影響範圍
web-demo/public/index.html：新增切換鈕、分隔線與工作區id。web-demo/public/styles.css：新增三欄網格（var(--rail-width)+ 分隔線欄）、分隔線與切換鈕樣式、收合狀態、行動版規則。web-demo/public/app.js：新增版面狀態、localStorage存取、拖曳與鍵盤調整邏輯。web-demo/tests/browser.spec.mjs：新增 4 項回歸測試（桌面版切換持久化、拖曳／雙擊／鍵盤持久化、無效儲存值回退、行動版與 320px 無溢位）。docs/compatibility.md、docs/compatibility.zh-CN.md：更新 Browser Lab Playwright 覆蓋範圍說明。驗證
npm ci：通過。npm run build：通過（含miniexcel-wasmrelease 建置）。npm run test:e2e：28 項通過、20 項依既有桌面／行動版篩選條件跳過。1280px下切換與拖曳皆正確持久化；Pixel 7 與320px行動版在收合後仍無橫向溢位。1280px為380px + 14px + 854px、901px為380px + 14px + 475px、412px與320px為單欄滿版，document.scrollWidth等於視窗寬度。審查重點
localStorage的width。320px）是否維持單欄且無橫向溢位。Summary by CodeRabbit
