/* ==========================================================================
   Codic Systems — site.css
   --------------------------------------------------------------------------
   Design notes, so the next person changing this knows the rules:

   · Navy is the ground, white is the page, green is a seasoning. Green appears
     on roughly one element per view — a rule, a code, a single word. If a
     screen has three green things, one of them is wrong.
   · No gradients, glows, bevels or drop shadows anywhere. The brand forbids
     them and the restraint is what makes the hairlines read as deliberate.
   · Outfit carries the voice. A monospace utility face carries the data —
     registration numbers, codes, timings, labels. That split is the signature:
     this is a company whose credibility is verifiable, so the verifiable parts
     are set in the face that machines use.
   · Type scale is fluid via clamp(). There are no media-query font sizes.
   ========================================================================== */
