   BIRD ATLAS — THEN. NOW. ALWAYS.

   An archive, not a toy. Aged paper, ruled ledgers,
   mounted photographs, film grain, gold hairlines, and
   letterspaced archival labels.

   Tap targets stay at 48px and the language stays plain,
   because a child and a grandparent use this at the same
   table.
