/**
 * Bootstrap-flavoured UI layer.
 *
 * Loaded after frontend.css when Design → Bootstrap UI layer is on. It only
 * refines typography, cards, buttons, navigation and the AJAX filter bar, so
 * the layout engine, RTL sheet and dark-mode tokens keep working untouched.
 * Every colour reads a theme token first and falls back to a literal, so the
 * dashboard colour pickers still drive the palette.
