/*
 * AI Store Optimizer — front-end styles.
 *
 * Ported and namespaced from the design bundle's atida-preview.html. Every
 * rule is scoped under `.aiso-sections` so it cannot collide with the host
 * theme. Brand tokens live on the root .aiso-sections element. No global
 * resets, no shadows except subtle hover transitions, font-weight never
 * exceeds 600.
 *
 * In scope: shared helpers (.block / .section-head / .section-icon), About,
 * How-to-use timeline, SEO content block, Top categories, Ways to save,
 * FAQ accordion, Reviews, Similar stores. Out of scope (theme owns):
 * header, breadcrumb, store hero, trust strip, coupon list, footer.
