/* rongan.me/social — light, warm, crisp.
   Two hard rules, learned in production:
   1. System fonts only — zero font requests inside Instagram/TikTok webviews.
      ui-rounded/SF Pro Rounded matches the apps' own design system.
   2. No filter/backdrop-filter anywhere. WKWebView lets blurred children
      escape border-radius clipping (the old avatar-glow corner artifact).
      Gradients and box-shadows only. */
