/*
 * tnk/faq-accordion — defensive <summary> color.
 *
 * Without this rule, the question line in each accordion item inherits a
 * near-invisible browser/theme default grey on TT5-derived child themes
 * that ship no per-element typography for raw <summary>. theme.json has
 * no schema for targeting <summary> inside core/details (verified against
 * WP 6.9), and a core/details block style variation cannot reach the
 * <summary> child — so a minimal CSS rule is the only place this fix can
 * live. Enqueued sitewide from tnk-patterns-styles.php for the same
 * has_block-cost reason that comparison-table.css is.
 *
 * Scoped to .is-style-faq so the patterns library does not influence
 * unrelated core/details usage on consumer sites. Consumer themes can
 * override by registering a higher-specificity selector.
