Read flat, tall and surface levels

Read metadata without building every maze

import {levelOf,mazeLevelsOfSize} from "@johnmorrisdotca/meikyuu/levels";
import {tallLevelOf,tallLevelsOfSize} from "@johnmorrisdotca/meikyuu/levels/tall";
const level = levelOf("maze",1)!;
const tall = tallLevelOf(1)!;
console.log(level.code,mazeLevelsOfSize("small").length,tall.width,tallLevelsOfSize(tall.size).length);

Level numbers start at 1; array positions start at 0. Flat maze sizes have names, while tall sizes are indices 1–6 and have a separate width field. Colossal square/tall lists are independent collections. Empty filters or unsupported sizes can produce empty arrays; missing numbered levels return null.

Import the surface collection you need

/3d/levels has the first solids; /dice and /shapes have additional collections; /all combines them. The same finder names operate only on that entry's data. A shape absent from an entry has an empty list. /3d/levels/recipes is the lighter recipe-only reader for a host that does not need score/effort metadata.

Keep the recipe code with saved solves. Major releases 2 and 3 changed numbering; a number alone needs the exact list/version. Maze collections now use geometry-aware score order, while arrows/mixed retain native effort order. See LEVELS.md and migration.
