I2 (test_pane_manager.py): 46 nouveaux tests
  - Module structure: 10 tests (exports, methods, factory, max panes)
  - Data flow: 8 tests (drag format, tree format, JSON, migration, localStorage)
  - DOM flow: 7 tests (grid, IDs, lazy render, collapse, empty pane, transfer)
  - Keyboard: 6 tests (all shortcuts + preventDefault counts)
  - Context menu: 4 tests (split, move-to, close actions)
  - CSS: 7 tests (grid, container, resize, drop zone, buttons, responsive)
  - HTML/App: 5 tests (wrapper, tab-bar, modules, imports)
  - Palette: 3 tests (commands, reset, category)
  - Editor lock: 2 tests
  - Dashboard: 1 test (TabManager vs openFile)

I3 (tests/e2e/): suite Playwright complète
  - package.json, playwright.config.js, split-view.spec.js
  - 12 test specs: basic ops, tab drag, tree drag, persistence, regression, keyboard nav
  - Exécution: cd tests/e2e && npm install && npx playwright test

Total: 353 tests passent (307 + 46)

"""
Tests for the Multi-Pane Split View (#75).
Tests for the Multi-Pane Split View (#75) — I1 + I2 + I4 combined.
Since PaneManager is a frontend JS module, these tests verify:
1. Backend integration: all file/sidebar/vault APIs still work (no regression)
2. Static file serving: pane-manager.js is served correctly
3. CSS: style.css includes pane grid classes
4. HTML: index.html includes the content-wrapper structure needed for panes
Covers:
I1: Unit tests for PaneManager JS module structure
I2: Integration tests (JS code patterns, DOM flow, data formats, CSS classes)
I4: Backend regression tests
