<title>, the navbar brand text, and the logo were all hardcoded "Proxy - Theta 42"/"Dynamic Proxy". New conf.name/conf.logo keys (defaults matching current text/asset) thread through the existing values object pattern in routes/render.js and routes/docs.js, and top.ejs now renders <%- name %>/<%- logo %> for the title and a new navbar logo image. Footer (copyright, theta42.com link, GitHub/license links) and the existing favicon.svg are left as-is -- open-source attribution and a distinct, already-working icon asset, not deployment branding.
