   SentSee — Landing（Apple design 參考）
   依 emilkowalski/skills apple-design SKILL.md：
   - 系統字型為預設；字級越大、字距越緊（-0.02em），內文趨近 0
   - 階層靠「字重 + 字級 + 行高」：顯示 1.06 / 內文 1.55
   - 材質分層：半透明 + backdrop-filter 的結構鉻，內容從底下捲過
   - 動效只動 transform / opacity；按壓當下給回饋（:active ~100ms）
   - 尊重 prefers-reduced-motion / reduced-transparency / contrast
   - Craft：每個數值都有理由；Simplicity：先給最常用的路徑
