/* QilyLean Curated Brief Unified Layout Standard
 * Canonical rule for EVERY curated brief:
 * - same sitewide 1180px content axis as the rest of QilyLean
 * - content may differ; page width/layout framework may not
 * - no private 920/1080/1220/1240/1560 article axis, no per-issue hero width, no standalone layout
 * - typography must follow one hierarchy; body/supporting text never outranks headings
