- EcommercePage.tsx:
- Introduce CommerceScenarioKey type (popular/poster/mainImage/scene/festival/model/background/retouch/salesVideo) and CommerceScenarioTemplate interface with scenario/output/desc/badge fields
- Add commerceScenarioOptions (9 scenario tabs with icons) replacing cloneOutputOptions as toolbar data source; each scenario maps to an output mode via commerceScenarioOutputMap
- Add commerceScenarioTemplates (16 templates across 8 scenarios) with thumbnail, badge, title, and description; popularCommerceScenarioTemplates aggregates cross-scenario highlights for the "热门" default tab
- Replace activeCloneTemplateCards with activeCommerceScenarioTemplates filtered by scenario; popular tab shows highlights, others show scenario-specific templates
- handleCommerceScenarioClick: switch scenario, auto-toggle output mode, toggle template strip visibility; clicking active scenario toggles strip; popular tab preserves current output
- handleCloneTemplateCardClick: auto-switch output mode to match template, fill prompt, focus textarea with 80ms delayed re-focus for reliability
- Template card markup upgraded: media thumbnail (94px cover image with hover scale), body with badge pill, title, and 2-line description
- Active scenario button shows close indicator (CloseOutlined) when strip is open
- Template strip defaults to visible (isCloneTemplateStripVisible initial true)
- Add "左右滑动查看更多" scroll hint for narrow viewports
- ecommerce-standalone.css (+355 lines):
- Scenario tabs: horizontal flex scroll with hidden scrollbar, pill-shaped buttons (grid: 24px icon + fluid label), per-scenario color accent via --mode-accent custom property (pink for popular, orange for poster/festival, green for mainImage/scene/background, blue for model/retouch/salesVideo)
- Active/open states: radial gradient glow, lifted shadow, intensified border color
- Icon slot: 24px rounded square with tinted background and inset highlight
- Close indicator: absolute top-right circle with hover scale
- Template cards: 2-column grid (94px media + fluid body), badge capsule, thumbnail with hover scale(1.035), title 820 weight, 2-line description clamp
- Responsive: ≤1024px 2-col card grid, ≤900px scroll-hint visible + left-aligned tabs, ≤640px horizontal scroll cards with snap, compact card sizing
- generationRecordClient.ts: Enhance save deduplication with payload signature — replace simple recordId-based dedup with stableJsonStringify-based signature comparison; same recordId + same signature skips save, changed payload proceeds; add buildSaveSignature covering tool/mode/title/status/prompt/taskIds/assets/config/result/metadata; store signature alongside savedAt in recentlySavedRecords map for per-turn save accuracy
- EcommercePage.tsx: Introduce EcommerceHistoryTurn interface and multi-turn conversation architecture —
- Add EcommerceHistoryTurn with full generation context (status/output/platform/market/language/ratio/requirement/images/results/counts/modules/scenes/replicateLevel); EcommerceHistoryRecord gains status/errorMessage/turns[] fields
- beginEcommerceHistoryTurn() — start a new generation turn, create or append to record, persist to localStorage immediately
- updateLocalEcommerceHistoryTurn() — real-time turn status sync (generating→done/failed) with record summary mirroring via syncRecordSummaryWithTurn()
- restoreHistoryTurnInputs() — one-click parameter restoration from failed turns for retry
- upsertCanvasNode() — insert or update canvas node by ID (dedup by turnId), alternating row layout (x: index*420, y: 0 or 160)
- Generate flow wired to turns: status callbacks update turn state; cancel sets turn to failed; results written to turn.results
- Record detail conversation panel refactored from single-message to per-turn iteration — each turn renders user message (requirement + meta + assets) and assistant message (status-aware text + progress bar during generation + result thumbnails); failed turns show "恢复参数" retry button; generating turn shows EcommerceProgressBar
- openEcommerceHistoryRecord() loads all turns as canvas nodes with distributed positions; preserves generating turn tracking via activeHistoryTurnIdRef
- History list items display status label (生成中/失败/time)
- Product set preview backdrop moved to createPortal(document.body) with z-index 4000
- pages/ecommerce.css: Bump product-set-preview-backdrop z-index from 100 to 4000 for Portal rendering layer
- EcommercePage.tsx: Add isCloneConversationCollapsed state for toggling conversation sidebar; introduce isMainCloneWorkspace / isRecordDetailWorkspace derived flags to scope record-detail features to main clone tool only; compute currentResultCount, activeHistoryRecord, and currentResultThumbs for display; add canvas reset button (zoom=1, offset=0) in preview toolbar when viewing a history record; build AI conversation panel (clone-ai-conversation-panel) as left sidebar with:
- Header showing record title, model/platform/language metadata, and collapse button
- User message bubble with requirement text and uploaded asset thumbnails (up to 4 + overflow count)
- Assistant message bubble with status-aware response text (done/generating/failed/idle), EcommerceProgressBar during generation, and clickable result thumbnails that open product set preview
- Collapse/expand toggle button with MenuFoldOutlined / MenuUnfoldOutlined icons
- ecommerce-standalone.css (+1204 lines): Define record detail workspace layout (CSS grid: 352px chat column + fluid canvas); grid-pattern background with radial gradient accent; conversation panel styling with chat bubble cards, asset thumbnail grids, result thumbnail buttons, scrollable body; collapsed state (grid-template-columns: 0 1fr); toggle button positioning; responsive breakpoints for tablets and mobile with adjusted chat width and stacked layout
