/* Klara Code — klaracode.dev
   Dark by commitment, not by default: the studio mark is an iridescent sphere on
   black, so the whole page is built on that ground. Every colour below is pulled
   from the mark itself — amber, orange, magenta, violet, blue, cyan.
   Type: mono for the wordmark, labels and data (the code-window motif);
   a humanist serif for prose, which keeps neon from tipping into arcade. */
