/*
 * Bir Hospital public site - design system (tokens, typography, accessibility, shared components).
 * Loaded after style.css so the tokens and base typography apply to every public page.
 * Brand colours are variables only: change them here (or override :root from a CMS-driven <style>) - never inline.
 *
 * Kalimati: no font file ships with the project. Copy Kalimati.ttf or .woff2 (and Kalimati-Bold.*) to
 * public/frontend/website/fonts/ (website) and public/fonts/ (admin); until then the Devanagari stack falls back
 * to a locally installed Kalimati, then Noto Sans Devanagari (loaded from Google Fonts), then Mangal.
