/*
 * Look of jaipuriaalumni.ac.in, carried over so the app matches it.
 * The first part is the site's own inline CSS (same values), including its quirks: it overrides
 * --bs-primary and --bs-secondary but not --bs-link-color-rgb or the focus ring, so plain links and
 * focus glows stay Bootstrap blue just as they do on the live site.
 * The second part holds this app's own components, built from the same tokens.
