   The palette is MEASURED from the federation's own logo artwork (see
   docs/00-context.md), not chosen. Everything else follows from it.

   Two contrast facts drive most of the colour decisions:
     - #008DD2 on white is about 3.4:1. Fine for rules, borders and large
       type; NOT enough for body text, so links use a deepened blue.
     - #FFDD00 on white is about 1.3:1. It can never carry text. It is a
       structural accent only — bars and edges, echoing the flag.

   No external requests: no font CDN, no analytics. The file:// preview in
   local/ must work with nothing but the files on disk.
