/* =========================================================
   Instagram Bio Formatter — tool-specific styles.
   Layered on /tools/_shared/tool.css.

   Two visual layers:
   1. The editor (uses the shared design system; theme-aware)
   2. The .ig-frame preview (locked to Instagram's mobile light view
      regardless of the tool theme — point is to look like Instagram)
