Right now there’s a manual index on the home page, but I don’t have a good way to see all the pages by category. Some of these are mainly for me but maybe I should make them all public.

1. Implementation category: vue, regl, canvas, svg, etc.
2. Feature category: printable, save-as-able, no-js-required, wayback compatible
3. Topic category: pathfinding, grids, hexagons, maps, voronoi, etc.
4. Difficulty category: beginner, intermediate, advanced
5. Knowledge category: reference, algorithms, implementation
6. Publish category: draft, published, abandoned
