"""
Information Spaces package for MarkiTect.

This package provides the Information Space abstraction, enabling:
- First-class space entities with identity, metadata, and lifecycle
- Event-driven change tracking and notifications
- Persistent transclusion context with cross-space references
- HTML rendering with caching and theme support
- Bidirectional directory synchronization
- Composable space hierarchies

Package Structure:
    - models: Core domain models (InformationSpace, SpaceDocument, SpaceConfig)
    - events: Event system (SpaceEvent, EventBus, handlers)
    - repositories: Data access layer (ISpaceRepository, SqliteSpaceRepository)
    - transclusion: Persistent transclusion context and reference tracking
    - rendering: Space rendering (HTML, themes)
    - sync: Directory synchronization (export, import, bidirectional)
    - services: Business logic (SpaceService)
    - history: Optional git-based version control

Usage:
    from markitect.spaces import SpaceService, InformationSpace

    service = SpaceService()
    space = await service.create_space("my-docs")
    await service.add_document(space, "/intro.md", content="# Intro")
    await service.render(space, output_dir="./html/")
