/* yfeld.de design system — implements docs/plan/04-design.md.
   Calm, typographic, fast. System fonts, no JS, one accent color.
   Mobile-first: base styles are the phone layout; the only width
   breakpoints are (min-width: 40rem) and (min-width: 64rem).
   Widths use rem/ch/min()/clamp() — never a fixed px width over 320px
   outside a media query — so the page never scrolls horizontally. */
