New skill for visual brainstorming: generate AI design variants, open a
comparison board in the user's browser, collect structured feedback, and
iterate. Features: session detection (revisit prior explorations), 5-dimension
context gathering (who, job to be done, what exists, user flow, edge cases),
taste memory (prior approved designs bias new generations), inline variant
preview, configurable variant count, screenshot-to-variants via $D evolve.
Uses {{DESIGN_SHOTGUN_LOOP}} resolver for the feedback loop. Saves all
artifacts to ~/.gstack/projects/$SLUG/designs/.
