/**
 * faqsnow-blocks.css — the FaqsNow theme's authoritative visual styling
 * for every faqsnow-core block/component class (Quick Answer, FAQ,
 * Sources, Related Questions, AI Tool, Comparison, Key Takeaway,
 * Warning/Info), front end and editor alike.
 *
 * CSS layering contract (Phase 4/5): faqsnow-core/assets/css/blocks.css is
 * a minimal functional fallback only — no brand colors, no typography
 * system, no card styling. THIS file is the design system for those same
 * classes. It is enqueued with an explicit dependency on the plugin's
 * 'faqsnow-blocks' handle (see inc/enqueue.php,
 * faqsnow_enqueue_block_overrides()) so it always prints after the
 * plugin's fallback, regardless of which one is actually enqueued first.
 *
 * Every selector below is a single class at specificity (0,1,0), matching
 * the plugin's own selectors exactly — no ID selectors, no `!important`,
 * no raised specificity anywhere. This is a straightforward override, not
 * a specificity fight.
 *
 * These components render in two different contexts and this file has to
 * look right in both: (a) inline, wherever an editor placed a block
 * inside the_content() — nested inside .fn-article__content; and (b) at a
 * theme-fixed position (Quick Answer, FAQ, Sources, Related Questions) —
 * a direct sibling of .fn-article__content, inside .fn-article. Every
 * rule below is written to be correct in isolation rather than relying on
 * .fn-article__content's prose styling cascading in.
