/*
 * Only the pieces Bootstrap doesn't already provide: brand theme colors,
 * the app shell (top bar + sidebar), the login screen, and a couple of
 * small custom components (status pill, ref-number monospace). Everything
 * else (buttons, cards, alerts, forms, tables, grid) uses Bootstrap classes
 * directly in the markup — duplicating those class names here would win the
 * cascade (this file loads after bootstrap.min.css) and silently override
 * Bootstrap's own component styling.
