   Cortado Labs — placeholder stylesheet

   Intentionally simple and neutral. Real design direction (colors, type,
   imagery) will be provided later, so everything visual is centralized in
   the CSS custom properties below to make it cheap to swap out.
   Do not over-invest in visual polish here. See CLAUDE.md.
