/* BX1 Group — site theme.
   One clean system implementing the final rendered design of the handoff
   reference (the "Bold" petrol/teal/amber theme). The reference applied this
   look as an override stylesheet fighting an older inline theme; here the
   merged result is expressed directly. Design tokens follow the handoff README.

   Geometry: border-radius 0 everywhere, no decorative shadows, 4px grid gaps,
   ~76px section rhythm, 1360px max content width.
   Type: Barlow Condensed (headings, uppercase) / Barlow (body) / IBM Plex Mono
   (figures, labels, eyebrows). */
