Modern Sports Team Logos

Objective:
Create a cohesive set of square vector icons representing various major sports leagues. The icons must be stylistically consistent and visually aligned with the aesthetic seen in reference images 1 and 2.

Scope:
Design icons for the following sports leagues below
• NBA: https://www.nba.com/teams
• NFL: https://www.nfl.com/teams/
• AFL: https://www.afl.com.au/teams
• NRL: https://www.nrl.com/clubs/

Design Requirements:
• Format: Vector (SVG)
• Shape: Square canvas, any shape within that
• Style: Sharp, clean lines with high visual clarity
• Consistency: All icons must follow a unified design style — same proportions, line weights, treatment, and visual language
• Detailing: Avoid clutter; prioritize recognizability and legibility
• AI Use: Use of AI-generated artwork is not recommended unless refined to meet the standards of clean vector artwork, eg: generate in AI, tidy up in Illustrator. They need to be pixel perfect.
• Output: Deliver individual SVGs for each league, named appropriately, including proper layer naming, eg: nba-chicago-bulls.svg

Below images define the design direction and must be matched in quality and style

Notes:
This is a precision-focused task — icons must be pixel-perfect, professionally balanced, and visually harmonious as a set.
