Quick Look Plan

Current State

Quick Look thumbnail and preview extension targets are present in the project and share the app's Bedrock package inspection layer:

World Manager for Minecraft/Services/MinecraftPackageInspector.swift
- extracts .mcworld, .mcpack, .mctemplate, and .mcaddon
- normalizes archives with either flat contents or a single nested top-level folder
- infers pack type for ambiguous .mcpack and .mcaddon archives
World Manager for Minecraft/Services/MinecraftContentMetadataReader.swift
- shared manifest, icon, display-name, and world metadata parsing
World Manager for Minecraft/QuickLook/MinecraftPackageTypes.swift
- central UTType identifiers and extension definitions
World Manager for Minecraft/QuickLook/MinecraftPackageQuickLookModel.swift
- preview-friendly summary model
World Manager for Minecraft/QuickLook/MinecraftPackageThumbnailRenderer.swift
- branded thumbnail rendering with icon fallback
MinecraftPackageThumbnailExtension/ThumbnailProvider.swift
- renders Quick Look thumbnails for supported Minecraft package files
MinecraftPackagePreviewExtension/PreviewViewController.swift
- renders a basic image preview from package icons or generated thumbnail art

Archive inspection is covered by tests in World Manager for MinecraftTests/World_Manager_for_MinecraftTests.swift.

The target layer is intentionally thin, but the preview experience can still be improved:

render structured metadata with MinecraftPackageQuickLookModelBuilder
include:
- package icon or branded artwork
- title
- package kind
- key facts like version, UUID, minimum engine, game mode, difficulty, and last played
add explicit UI tests or fixture-driven render tests for package previews

xcodebuild ... build succeeds.
xcodebuild ... test should be run before release and whenever the shared archive inspection layer changes.
