/**
 * File:     public/assets/css/app.css
 * Project:  Bistro Control (PHP/MySQL rewrite)
 * Version:  1.0.0
 * Updated:  2026-09-26
 *
 * Purpose:  Visual style ported 1:1 from the original React/Tailwind
 *           prototype (glassmorphism cards + neumorphism inset forms).
 *           Written as plain CSS (no build step / no Tailwind) so it
 *           runs on a bare PHP/MySQL shared host with zero tooling.
