   Kalibr — /start
   Work with us. One job: turn a tap from a bio link into a qualified call.

   TYPE. Kalibr's own stack, unchanged from the homepage: Archivo display,
   Instrument Sans body, JetBrains Mono labels. Distinctiveness here comes from
   the 3D mark and the motion, not from borrowing someone else's typography.

   STANDALONE. Does not use styles-v11.css. That file is 53KB, render-blocking,
   and the homepage LCP is already over budget; this page carries only its own.
   The :root token block is copied from it and must be kept in sync by hand.
