   BARNES PROJECTS — index.css
   Classic / minimalist restyle. A scientific-monograph aesthetic:
   ink on paper, Playfair Display + Inter + JetBrains Mono, a single
   restrained nobel-gold accent. Light is the default theme; body.light
   holds the light palette, the bare body holds the dark palette (toggle
   driven by index.js, key: barnes-lcars-theme).
