// Claude — measured design system as an Astryx theme.
// Decoded live from the real page by Mozaika: colors by role, type scale, radius,
// motion timings and real hover/press states — measured, not guessed.
// Decoded with Mozaika — full system + other formats: mozaika.design/decode/claude.ai
// Usage: <Theme theme={claudeTheme}>…  (Astryx needs React 19;
// import '@astryxdesign/core/astryx.css'; build for SSR: npx astryx theme build <this file>)
