/* BWA FAQ Module */

/* ========== Base Styles ========== */
/* Brand wiring. Each role resolves into a distinct local var (--faq-*) so
   there is NO self-reference cycle. Resolution order:
   1. recolor token (--bg/--text/--accent/...) injected by the stan AI Assist
      agent on this root class.
   2. inherited --bwa-faq-* emitted at :root by BrandCorpusController from this
      plugin's manifest brandInheritance (folder slug = "faq").
   3. the literal fallback — the module's original default. */
