/*
 * Foundry — the Tendra Systems design system for internal tools, as one
 * plain-CSS file for apps without Tailwind (static pages, server templates).
 * Tailwind / shadcn apps use foundry-tailwind.css instead.
 *
 * Source of truth: docs/foundry/ (tokens/, guidelines/, components/).
 * Rules: docs/design-system.md.
 *
 * Copy this file and fonts/ next to it. Fonts are self-hosted: apps must
 * render with no internet. Archivo has no Cyrillic, so Ukrainian text falls
 * back to the system sans; that is expected.
 *
 * Theme: light by default, dark when the OS asks for it. `data-theme` on
 * <html> pins either one regardless of the OS.
