/**
 * A namespaced, shape-safe attribute bag. Deliberately NOT
 * `Partial<Record<...>>`: `Partial` would type every property as
 * `AttributeValue | undefined`, and this repo's tsconfig does not set
 * `exactOptionalPropertyTypes` — so a `Partial` version would let
 * `{ 'namzu.x.y': undefined }` compile, an attribute that is present and
 * holds nothing. Plain `Record` over a template-literal key domain does not
 * require every possible key to appear — there is no finite set of keys to
 * require — so dropping `Partial` costs a caller nothing: it still supplies
 * only the keys it has, and gains that an explicit `undefined` is rejected
 * the same way `null` and a nested object already are.
