Introduce an interactive Four Color Theorem demo: add FourColorComponent (template, styles, standalone component) with canvas-based grid, region generation, adjacency detection and a backtracking solver; include models for nodes/regions and grid constants. Wire up route and RouterConstants/UrlConstants, add menu entry in AlgorithmsService, and add i18n entries for English and German. Also add global color styles in styles.scss and a few minor i18n text adjustments.
Add active state support to topbar links (routerLinkActive) and CSS underline/hover styling; expose icons for algorithm categories and render them in the algorithms list. Update AlgorithmCategory interface and AlgorithmsService to include icon names, import MatIconModule where needed, and adjust algorithms template to show icon, title and description layout. Global style tweaks: dark theme background, canvas shadows, card hover/gradient accents, and new styles for algorithm cards and page title for improved visual polish.
Introduce TimSort support across the app: add TIM_SORT_WIKI to UrlConstants, implement timSort (with insertionSortRange and mergeRanges) in SortingService to produce SortSnapshot sequences (uses RUN=32, sorts runs then merges, marks comparing/unsorted/sorted states), and wire the algorithm into SortingComponent (UI entry and case branch). Also add TIMSORT_EXPLANATION translations in de.json and en.json, and add a few UI label keys (STIFFNESS, ELONGATION, RESTART_SIMULATION) to both locale files.
Switch route definitions to lazy-load components via loadComponent dynamic imports and remove direct component references from RouterConstants. Remove several components' standalone flags and adjust component metadata (styleUrl vs styleUrls) and imports accordingly. Make AlgorithmsService and AlgorithmsComponent synchronous (getCategories() now returns an array and template iterates categories directly). Replace alert in PathfindingComponent with MatSnackBar and inject it. Simplify LanguageService initialization to use existing translate configuration. Remove unused ReloadService. Make GenericGridComponent.lastCell protected. Miscellaneous tidy-ups across related files.
Add a new CLAUDE.md project guidelines file. Update BabylonCanvas to replace alert() with an Angular Material MatSnackBar and use ngx-translate for a localized WebGPU-not-supported message (injects MatSnackBar and TranslateService and updates imports). Add the corresponding WEBGPU.NOT_SUPPORTED entries to en.json and de.json for localization.
Update package-lock with multiple dependency bumps (Angular CLI/DevKit/schematics to 21.1.5, ajv to 8.18.0, minimatch/brace-expansion updates, tar, qs, swiper, hono, etc.). Wrap the generic grid canvas in a container and clean up HTML structure/indentation in algorithms and pathfinding templates (add card-grid wrapper and reformat content). Adjust global styles: refine .algo-container and app-root margins/gaps, and refactor hero/photo/intro styles for responsive layout. Changes are primarily dependency updates and UI/layout refinements.
