Comprehensive code audit addressing naming consistency, dead code removal, and documentation improvements across the entire codebase. - Rename panel_pages.rs → pages_panel.rs for consistent naming - Unify view functions: all panels now use view() convention - Rename header_start/end() → start/end() for brevity - Update all imports and references - Remove Rotation::from_degrees() (only 4 fixed states needed) - Remove TransformState::identity() and is_identity() (Default suffices) - Remove duplicate convenience methods from RasterDocument, VectorDocument, PortableDocument (rotate_cw/ccw, flip_horizontal/vertical) - Remove unused imports and constants (ROTATION_STEP, FULL_ROTATION) - Rename constants: PDF_RENDER_SCALE → PDF_RENDER_QUALITY, PDF_THUMBNAIL_SCALE → PDF_THUMBNAIL_SIZE - Add comprehensive trait documentation explaining type erasure pattern - Document why large enum variants are acceptable - Add #[allow(dead_code)] with explanations for trait API types - Improve all constant and config comments - Collapse nested if statements using Rust 2024 let-chains - Replace single-arm match with if-let - Introduce StateChangeCallback<Message> type alias - Apply clippy auto-fixes for better code style
