Create a coordinated family of three editorial 2D illustrations for Still, a fictional budgeting app. Subjects: Save (a reassuring place for small reserves), Spend (thoughtful everyday choices), and Grow (steady progress, not overnight wealth). Use warm off-white, deep purple, soft coral and moss green. Keep the tone calm, optimistic and tactile, with simple silhouettes and considered negative space. Each illustration must feel part of the same family through palette, proportions and mark-making. Supply each subject as a separate editable SVG on a transparent 480 × 400 canvas. No text, brand marks, gradients, photographs or embedded raster images. Keep the subjects readable at website-card size. This is the shared design brief for interface demonstration artwork, not a recorded model prompt or evaluation.
