/*
 * DesignAChip powered by Aizen, preview site stylesheet. Load css/tokens.css first, it holds the brand tokens.

 * Contents
 *   1. Names used on this site, all pointing at the brand tokens (dark is the default, light is a full second theme)
 *   2. Base
 *   3. Shell, rail, top bar, preview bar
 *   4. Components (hud panel, buttons, tags, tables, forms)
 *   5. Template lights (DASH speed lines, HAYDN resonance pulses, LIAM slow glow)
 *   6. Pages (home, wizard, family, market, protect, claims, abilities, pricing, sign up)
 *   7. Start screen and world layer
 *   8. Reduced motion, paused motion and small screens
 *
 * Fonts. The brand names Chakra Petch, Schibsted Grotesk and JetBrains Mono. This site loads no font file
 * from anywhere, so those names apply only where a visitor already has them installed. Everyone else gets the
 * system fonts that follow them in the stack.
 * Motion. Nothing flashes. The fastest repeating change is a slow drift, pulse or breath with a period of
 * about two seconds or more. Every colour that carries text is checked by tests/contrast.test.js.
