CSS Changes:
- Removed all overflow/max-width/word-break rules from body/html
- Simplified to match WebView.swift CSS structure exactly
- Only img keeps max-width: 100%
- Removed box-sizing and universal max-width rules
JavaScript Height Detection:
- Simplified from Math.max() with multiple properties to simple document.body.scrollHeight
- This matches how the standard WebView gets height
- Should resolve 'No valid JavaScript height found' errors
The width overflow was caused by aggressive CSS rules that interfered
with native layout. The height detection issue was likely due to complex
JavaScript expressions not working with webPage.callJavaScript().
- Added universal max-width: 100% to all elements
- Added overflow-wrap, word-wrap, and word-break to body
- Added overflow-x: hidden to html
- Fixed pre blocks with white-space: pre-wrap and max-width
- Fixed tables with display: block and overflow-x: auto
- Added word-wrap to table cells
This prevents wide content (long URLs, code blocks, tables) from
overflowing the viewport width in iOS 26+ NativeWebView.
- Created BookmarkDetailView2 with native SwiftUI WebView (iOS 26+)
- Refactored BookmarkDetailView as version router
- Renamed original implementation to BookmarkDetailLegacyView
- Moved Archive/Favorite buttons to bottom toolbar using ToolbarItemGroup
- Added toggle button to switch between native and legacy views
- Implemented onScrollPhaseChange for optimized reading progress tracking
- Added NativeWebView component with improved JavaScript height detection
- All changes preserve existing functionality while adding modern alternatives
