   Design rules (from approved landing page):
   - Bright backgrounds = dark text; dark backgrounds = light text
   - A card: white-green | B card: gold-beige | C card: deep emerald
   - D advisor + AI quiz: 门灵 purple accent
   - Package cards equal height, top-aligned, buttons pinned to bottom
   - No watermark text. Strong contrast on placeholders, disclaimers, eyebrows.
