/**
 * Berke System 0.6.0 — stabilized front-end contract.
 *
 * Purpose:
 * 1) keep a single typography scale and RTL composition contract;
 * 2) establish shared container/spacing/card/control behavior;
 * 3) normalize historical Berke/Elementor surfaces while they are migrated;
 * 4) avoid changing stored WordPress content.
