   bMail app.

   Continues the landing page's language rather than inventing a second one:
   confident Archivo headings, softly lit card surfaces, hairline structure, and
   yellow spent only where it means something. Monospace is reserved for things
   that are literally data — addresses, keys, amounts — and never used for
   labels, which is what makes an interface read as a console instead of a
   product.
