Bring your own model access. Five minutes to set up, then every playground is yours.

A prompt is a design variable. Treat it like a brand-voice swatch, not a magic spell.

Style is composable. Move warmth, verbosity, directness as independent dials.

Character design isn't decoration. Backstory, beliefs, and blind spots shape every response.

Where the model says no is a design surface. Over- and under-refusal both fail users.

Lists, headings, JSON, paragraphs. Format is part of voice; pick one on purpose.

Rubrics + sample sets. Score behavior the same way you score a usability study.

Conversations have shape. Choreograph turns the way you'd choreograph an onboarding.
