/*
 * VPS Base design system.
 *
 * 1. Tokens   - every color, space, radius and type size is a CSS variable.
 *               Light is the default; dark applies via prefers-color-scheme
 *               or [data-theme="dark"] (the header toggle). Never hard-code
 *               a color in a component: add or reuse a token.
 * 2. Base     - element defaults, focus ring, reduced motion.
 * 3. Layout   - app shell: left sidebar, mobile sheet, header, main.
 * 4. Components - one block per component; markup lives in
 *               web/templates/components.html. See documentation/design-system.md.
 *
 * Sizes: controls are 36px (--target) and small ones 32px (--target-sm)
 * with a mouse; on touch screens (pointer: coarse) both grow to 44px.
