<?php
/**
 * Addon Catalog — canonical metadata for every Double Opt-In addon.
 *
 * Single source of truth for addon names and descriptions. Used by:
 *  - the Addons admin page to render a marketplace grid (with state-
 *    aware CTAs that depend on whether the user has the addon
 *    installed, active, or has a bundle license),
 *  - the License-page Features Overview to surface bundle-covered
 *    addons even before they are installed (via bundle-pro's hook
 *    into the `f12_doi_license_features` filter),
 *  - bundle-pro's installer to humanize addon IDs in the install row.
 *
 * Under bundle-only licensing there are no per-addon purchase pages:
 * the single Pro bundle unlocks every module, so the UI points users
 * at one bundle upgrade CTA rather than a per-addon buy link.
 *
 * Lives in Core (not bundle-pro) so the marketplace UI works on free
 * sites without bundle-pro: the page can still show what addons exist
 * and point the user at the bundle upgrade.
 *
 * @package Forge12\DoubleOptIn\Addon
 * @since   4.4.0
