   Oven — landing page
   Hand-written CSS. No framework, no build step, no runtime.

   The palette is deliberately monochrome. Orange is an accent, not a theme: a
   status dot, a link arrow, one keyword class in the code, the focus ring.
   A page washed in a brand colour reads as decoration; a page that is mostly
   ink reads as a tool.
