   PROMPT IA — Styles
   Design Direction: BAUHAUS GEOMETRIC (Hard Rule #16 — unique to this tool)
   Palette/type/layout: cream base #f2ece0, flat primaries red #d8362a /
     blue #1f4ea1 / yellow #f2b705 + ink #15110c; heavy uppercase tracked
     geometric sans headings + system mono labels; flat colour blocks, 2.5px
     solid black borders, ZERO radius, NO shadows, strict composition.
   Signature: every prompt ingredient is a primary-colour geometric block
     (subject=square, style=circle, lighting=triangle) that assembles into the
     constructed prompt; constructed geometric logomark.
