/* Latlas design system: a trading terminal. Shared by the portal and every Grid Botty page.
   Near-black slate, phosphor-green signal, red for losses, amber for warnings. Square panels, fine grid,
   faint scanlines. Headings: Martian Mono. Data and figures: JetBrains Mono. Prose: IBM Plex Sans.
   Tailwind's color scales are remapped in theme.js, so existing utility classes follow the palette. */
