// ── Global constants & DOM shortcuts ──────────────────────────────────────────
//
// Provides app-wide constants and a concise DOM query shortcut.
// This module depends on nothing and is loaded first.
//
// Globals provided:
//   $                  → document.querySelector() bound once
//   $id                → document.getElementById() bound once
//   svgNamespace       → SVG namespace URI for createElementNS
//   STORAGE_KEY        → localStorage key used by persist.js

/** Shorthand for document.querySelector, bound once. */
const $ = document.querySelector.bind(document);

/** Shorthand for document.getElementById, bound once. */
const $id = document.getElementById.bind(document);

/** SVG namespace URI, required when creating SVG elements via JS. */
const svgNamespace = "http://www.w3.org/2000/svg";

/** localStorage key for workspace persistence (save/load/new). */
const STORAGE_KEY = "workspace";
