first real evening of code. mostly laying pipe under the floor.
added a .gitignore so target/ stops following me aroundwrote geom with Point, Dir and Rect helpers, the small stuff everything else leans onrolled my own rng, a seeded splitmix64. std only, no getrandom, i want catches to be reproducible from a seedstarted the tile module, the enum and per-tile glyphsno graphics, no game, just the vocabulary the rest of the code will speak in. slow but satisfying.
