/*
 * StackGrade frontend visual overrides.
 *
 * This file must remain empty by default. Only add rules here when a
 * deliberate visual change is explicitly requested. Never populate it
 * as part of a standard production cutover.
 *
 * Permitted: non-visual functional fixes (z-index corrections, etc.)
 * Forbidden: font-family overrides, border-radius !important, shadow
 *            overrides, or any rule that changes appearance relative
 *            to standalone stack-selector.
