/* =============================================================================
 * portal.css — единственият stylesheet на портала.
 *
 * Секция 1 (до реда "== край на мигрираните чат стилове ==") е МИГРИРАНА
 * ДОСЛОВНО от старото app/ui.py::_PAGE_HTML (<style> блокът) — вкл.
 * :root палитрата (--accent #2563eb и т.н.), която е design base-ът за
 * целия портал занапред. `header`/`#user-info` тук вече не се match-ват
 * от чат страницата (нейният <header> е заменен от .site-header по-долу —
 * "shell" промяна, изрично позволена), но правилата остават непокътнати,
 * за да е чат секцията 1:1 копие на оригинала.
 *
 * Секция 2 добавя общата рамка на портала (nav, footer, toast) и
 * admin компонентите (таблици, форми, tiles), с font stack, spacing и
 * :root палитрата, споделени с чат секцията.
