/* Layout (BOS-0406, 2026-10-16): one short page. Photo + name + one plain line on top, then the four sites as
   logo keys side by side (2 x 2 on a phone, 4 across from 760px); a tap opens that site's short story below.
   Then the contact panel (a quotes row is ready to paste in; see the comment in the page). Every corner is square. Buttons are mechanical keys
   in sockets. Dark only, on purpose. Type: Montserrat is the voice (black italic for big words, plain for
   reading); Michroma is the machine (section heads, key legends and the footer only). */
