Add the logo, a Viking jarl drawn like a woodcut whose spear-pointed crown holds a DNS tree. It is generated by scripts/logo.py, which mirrors the left half so the figure is exactly symmetrical, as logo.svg (white on a Nordic-blue disc) and logo-white.svg. It links home in the header, sits on the login page and is the favicon. The login page shows an angular "JARL" wordmark drawn as SVG paths over a rule with a "DNS" node, coloured from the theme. The header's "Jarl" uses a self-hosted Cinzel Bold subset (SIL OFL); jarld serves .woff2 as font/woff2. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
