Summary

• stop treating the BetterFit mark as a mascot or workout illustration
• use the supplied identity badge for greeting states and a functional profile avatar for users
• replace workout-card bars with a shared articulated vector rig for push, pull, legs, and cardio poses
• add independently colorable front/back anatomy shapes mapped directly to BodyRegion
• reuse the same body-map geometry in Plan and Recovery
• refresh README screenshots to show the corrected artwork

Asset roles

• Identity: supplied BetterFit artwork, no face or mood states
• Avatar: initials or system guest silhouette
• Movement: one vector rig with pose-specific joints and equipment
• Anatomy: region-addressable vectors for chest, back, shoulders, arms, core, and legs
• Mascot/pet: none, so no sprite system is introduced

Verification

• targeted SwiftLint: 0 violations in the new design-system files
• mise run ios:build:dev
• mise run test: 95 Swift tests and 23 pipeline checks pass
• visually inspected Workout, Plan, and Profile on iPhone 16 simulator
