/*
 * Precheck UI layer.
 *
 * Loaded last on every page, after Bootstrap and the ported PHP stylesheets, so the shared
 * components look the same everywhere: inputs, radios and checkboxes, switches, modals, alerts,
 * tables, badges and menus. Buttons and tabs are deliberately left as they were. It changes how
 * components look, never page layout.
 *
 * Bootstrap 5.3 components read CSS variables, so most of this sets those variables instead of
 * fighting specificity. Brand colour and font are unchanged (#1E7EF2, Gilroy).
