/*
 * Yuimaru User Guide — shared stylesheet.
 *
 * This deliberately reuses the real app's design tokens (colours, type, radius,
 * shadow) so the guide looks and feels like Yuimaru itself. Values mirror
 * web/src/styles/tokens.css. The little UI mock-ups in the guide (buttons,
 * cards, the save heart, toasts, status pills) are built from these same
 * tokens, so what you see here is what you see in the app.
