/*
 * openQCM 2026 — main stylesheet
 *
 * Design tokens (colors, fonts, sizes) live in theme.json. This file consumes
 * them via the --wp--preset--* CSS variables WordPress generates automatically.
 *
 * Naming: every custom class is namespaced under .openqcm-<component> to avoid
 * collisions with WordPress core blocks and any residual Elementor CSS during
 * the migration phase.
