/* ==========================================================================
   家族資產管理系統 — shared stylesheet
   Design system: Stripe (awesome-design-md/design-md/stripe/DESIGN.md)

   Two deliberate adaptations from the source system:
   1. sohne-var is proprietary, so the stack falls back to the platform UI sans
      plus a Traditional Chinese face.
   2. Stripe's signature weight 300 is unreadable for CJK glyphs at UI sizes and
      works against this site's elderly-friendly brief, so body text runs at 400
      and only large Latin-heavy display text goes lighter. Everything else --
      palette, blue-tinted layered shadows, 4-8px radii, tabular numerals for
      financial data, precision spacing -- follows the system as written.
