/*
 * site.css — the visual design system for music.rjnestor.com.
 *
 * Direction (decided 2026-07-22): a person-forward, editorial frame with no genre of its
 * own — the one constant is R.J. Nestor. A cool, non-seasonal palette pulled from the
 * headshot (porcelain, slate-teal from the eyes, petrol, dusty blue from the shirt, charcoal
 * from the piano). Literata for headlines/body, IBM Plex Sans for nav/labels/buttons.
 * Porcelain-light is the default; a warm-charcoal dark mode is the alternate.
 *
 * Mobile-first: base rules target small screens; one min-width query layers on the desktop
 * layout. Numerals are lining everywhere (no descending figures — a hard preference).
