# High Contrast Mono — pure black and white, no mid-greys.
# Huge type, hard edges, zero decoration. The stark poster — vs swiss, which
# keeps hairlines and grey. Nothing but ink and paper.

  # Charts are the one place this theme breaks its own rule, and it has to.
  # Colour on a chart is data, not decoration: with a black accent and a white
  # accent_alt the derived palette drew three identical black series and one
  # white one that disappeared into the page. Greys alone cannot carry four
  # series at a readable contrast either.
  #
  # These are flat poster primaries, which is the same design language the
  # display face and the hard black rules already speak. Ink leads so a
  # single-series chart still reads as this theme.

  prefers:
    - one idea, huge
    - short declarative statements
    - typographic contrast as the visual
  avoid:
    - mid-tones, gradients, shadows on text
    - more than one idea per slide
    - anything that softens the statement
  headline_style: >
    Say it flat and big. "BLACK AND WHITE" over "A Balanced Introduction".
    Remove every word you can.
  body_style: >
    Short, blunt, complete. One sentence per point. No hedging.
