 * Public surface theme — research-books.com brand.

 * app (which never loads this file) keeps its existing look.
 *
 * Tricolor system: warm cream backgrounds; navy for structure/authority;
 * coral (#e06656) as the accent; teal (#509ab6) as the interactive/link color.
 * Headings PT Serif; body/UI Josefin Sans. No top bar — the navy rail runs
 * top-to-bottom and carries the brand (top) + staff/links (bottom).
