Extract Story Lab assembly tab and library chrome i18n

[IAnMove]

Why

Assets left StoryLabPanel in #100. The Assembly tab and leftover library chrome (header, tab labels, project types, Guided/Automatic, prepare buttons, Cancel/Resume/Storypack/Import/Smart assets/New/Duplicate, nav notes) still mixed EN/ES inline.

What

• StoryAssemblyTab is presentational; StoryProductionTimeline stays here with initiallyOpen={index === 0}
• StoryLabLibraryChrome owns the header toolbar; public panel handlers (generate, exportStorypack, importStorypack, newProject, reopen/restore) stay in StoryLabPanel
• storyLabTabs.ts is data-driven (id: 'trailer', id: 'assembly'); labels come from i18n
• EN/ES storyLab catalogs for library chrome, project types, tabs, nav notes and assembly copy
• Python/UI source contracts retargeted to catalogs / storyLabTabs / StoryAssemblyTab

Does not touch useStore.ts or _launch_runtime.py. Independent of any in-flight useStore slice PR.

Checks

• eslint on extracted files + tsc -p tsconfig.app.json --noEmit
• i18n catalogs
• Story Lab UI extract tests (storyLabResponsive, i18nFoundation)
• test_story_lab_trailer_ui, test_series_lab_ui, test_story_lab_audio_ui

Humans merge; checks must be green.

Note

Low Risk
UI refactor and copy migration only; no changes to useStore.ts, backend, or generation behavior beyond wiring the same handlers into new components.

Overview
Pulls Assembly and the library header toolbar out of StoryLabPanel into StoryAssemblyTab and StoryLabLibraryChrome, with tab/project-type definitions centralized in storyLabTabs.ts. Generation, import/export, and reopen/restore handlers stay in the panel; the new pieces are mostly presentational and call back through props.

i18n (EN+ES): Adds storyLab keys for library chrome (save status, prepare buttons, Storypack/Import/Smart assets, etc.), project types, tab labels, nav notes, and assembly copy. StoryLabNavigation’s mobile swipe hint uses nav.swipe. The i18n pilot list and forbidden-literal checks cover the extracted files so mixed inline strings are blocked.

Tests/docs: Python UI contracts and Story Lab responsive/i18n tests now assert catalogs and storyLabTabs / StoryAssemblyTab instead of hardcoded strings in the panel. SLICE_QUEUE.md reflects Assets (#100) and describes this slice as the next Story Lab extract.

PR Review — Loreframe Studio

Risk: low
Scope: 13 file(s); +718/-217; React UI, docs

Automated review from scripts/analyze_pr.py. This is a heuristic pass (no LLM) so humans still own the merge decision.

Findings

• low — UI changed — rebuild before merge
  Run cd ui && npm run build (CI already does this). Pinokio Update rebuilds for end users; keep ui/dist untracked.

Changed files

• added: ui/src/features/stories/StoryAssemblyTab.tsx, ui/src/features/stories/StoryLabLibraryChrome.tsx, ui/src/features/stories/storyLabTabs.ts
• modified: docs/development/SLICE_QUEUE.md, tests/test_series_lab_ui.py, tests/test_story_lab_trailer_ui.py, ui/scripts/check-i18n-catalogs.mjs, ui/src/features/stories/StoryLabNavigation.tsx, ui/src/features/stories/StoryLabPanel.tsx, ui/src/i18n/locales/en/storyLab.json, ui/src/i18n/locales/es/storyLab.json, ui/tests/i18nFoundation.test.tsx, ui/tests/storyLabResponsive.test.tsx

CONTRIBUTING checklist

• python scripts/verify_clean_repo.py
• python -m compileall -q app/services app/launch.py scripts
• cd ui && npm run build if the UI changed
• No weights, CivitAI sidecars, or generated guides
• Stays local-first (no required accounts / telemetry)
