<?php
/**
 * Declarative registry of custom-event CONDITION types (Free variant): label +
 * value shape (rule_value / device / user_role). Mirrors CustomEvent::update()'s
 * conditions parser AND the full admin condition-type dropdown
 * (ConditionalEvent::$conditional_type_array).
 *
 * Free WRITABLE conditions via MCP: url_filters, device, user_role (see
 * WRITABLE_TYPES). url_parameters, landing_page, source and product_id are
 * PixelYourSite Pro conditions — kept here (mirroring the full admin dropdown) so the tool NEVER
 * reports a real condition type as "does not exist", an existing condition of
 * that type can still be read/labelled, and available_condition_types shows it
 * as `editable:false` (Pro). `isWritable()` returns false for those three.
