   Kyrillos Isaak — portfolio
   Hand-written CSS. No framework, no build step.

   Design language: instrument modules. A light grey ground, panels outlined
   in hard 1px near-black, every panel wearing a lowercase monospace label
   strip. Square corners throughout. Colour appears only where it means
   something. Light is the default; the dark toggle inverts the same system.
