   rmartorell.nl — dashboard
   Design: "aurora over donker water" — a warm/cool gradient-mesh
   backdrop with slow drifting light ribbons and a fine print grain,
   replacing any literal grid/wireframe motif. Fraunces carries the
   headline's warmth; JetBrains Mono is kept only as a small,
   restrained technical accent (eyebrows, tags, status); Manrope
   carries body copy.
