workspace-visual.json:
- Main: design-ideas.canvas (default) + Wiki Map + Graph view tabs
- Left: file-explorer, search, bookmarks

- Switch to it: quit Obsidian, cp workspace-visual.json workspace.json, reopen

Note: _attachments/images/ is NOT gitignored (images are intentional)
      Comment out the line in .gitignore to exclude them for leaner forks
