/*
 * panel.css — the project design system.
 *
 * A shadcn/ui-inspired skin layered on top of stock Bootstrap 5.3. The look is
 * a single light theme: monochrome (neutral zinc scale), quiet, and spacious, with
 * soft rounded corners and a single accent reserved for danger.
 *
 * How it works (the design workflow):
 *   1. Design tokens live in :root (the light palette).
 *   2. Those tokens are mapped onto Bootstrap's own --bs-* variables, so every
 *      Bootstrap component inherits the palette, radius and typography.
 *   3. A few components are refined by hand (buttons, forms, cards, tables,
 *      badges, modals, toasts, the sidebar) to match shadcn's detailing.
 * To restyle the whole app, edit the tokens — not the components.
