/* relics.css — one quiet editorial-minimal studio: tokens, themes and shared
   components. Direction (REDESIGN-BRIEF.md): ref.digital owns the navigation
   concept (in-flow header, oversized wordmark, bracketed links, square outline
   controls that invert on hover) and the deep-red accent; philipreadman.com owns
   the light theme and the tonal card language. Dark theme is an ideal neutral
   black scale. Flat material: separation by tone and hairline, no shadows, no
   glow. Native scroll; essential text visible at rest. */
