/* ============================================================================
   SermonBridge design system — Rev 19（2026-11-10 老板第 9 轮）
   方向：Sanctuary Neutral —— 近乎无彩的高级灰阶（石墨 → 暖白），
   靠排版（衬线标题 + 中性无衬线正文）、留白、玻璃与发丝线出质感。
   明确去掉「深色 + 高饱和暖金」的冲突配色；暖色只留在品牌标记的极小细节里。
   所有类以 sb- 前缀或专属语义命名，避免与 Tailwind CDN 工具类打架。
