/* ============================================================================
   muhkoo.com — shared stylesheet for every page.
   "Cryptographic Instrument", refreshed for a product site: geometric sans
   (Montserrat) headers against cold mono metadata on near-black ink, hairline
   blueprint rules, corner ticks, a faint coordinate lattice, grain — plus
   screenshots in browser and phone frames, API chips and alternating rows.

   Renaming rule: hosting serves every asset with a one-year immutable cache,
   so any change to this file ships as site.v4.css.

   Class contract — pages use these names and must not invent others without
   adding them here:
