/**
 * Using decorators in a file means shipping TypeScript's decorator polyfill.
 * Plus, the decorator polyfill is meant to be generic and so adds more code
 * than needed.
 *
 * Fortunately, Lit supports a static "properties" property (mainly for
 * non-TypeScript users) that can be used to define properties in a more
 * build size efficient way, without the need for `@property()` or `@state()`
 * decorators.
 *
 * @remarks
 * Without this, map-components CDN build is 398kb.
 * With lifted decorator, it is 364kb (34kb smaller).
 * AND, with compact property options it's 354kb (7kb smaller).
 *
 * For comparison, map-components Stencil CDN build is 370kb (and they
 * lift all decorators too).
