/* Car Catalog — styles.css
   Plain CSS, no preprocessors. Mobile-first responsive.
   Design system established Session 13 (2026-05-16):
   - Neutral palette, deep desaturated indigo accent.
   - Spacing + type scales, light/dark palettes, motion + radii tokens.
   - System fonts only (offline-first; no external font imports).
