   AXIOM SERVICES

   Design position: a technical specification, not a landing page.
   Structure is carried by hairline rules, indexes and tables. Not by cards.

   Deliberately absent: gradients, gradient text, glow shadows, backdrop blur,
   radial halos, icon tiles above headings, uniform icon-card grids, hover
   bounce, decorative pulses, content hidden until scroll.

   Type      IBM Plex Sans / IBM Plex Mono
   Ink       deep slate stock, from the logo's own #3A4352 family
   Accent    gold, used sparingly. Violet is reserved for live system state.
