   Loaded after templatemo-scholar.css and overrides its look:
   - violet of the real boards (OKLCH hue 307), Tailwind violet/slate scale
   - Inter for text, JetBrains Mono for labels (like the silkscreen on boards)
   - the hero is the one dark surface: slate-950, violet-500 glow at 30 %,
     heading highlight violet-300 -> fuchsia-300
   - PCB motifs (traces, vias, silkscreen frame) and schematic icons
