Research-first logo and app icon design for a product. Use when the user says '/logo-design', 'make an icon', 'design a logo', 'app icon for X', 'favicon for X', 'new mark for X', or wants icon/logo directions for an app, site, extension or Mac app. Runs parallel research (principles, competitor icons, curated marks, YouTube lessons) across several search engines, builds mood boards, offers 10+ grounded directions, then generates and critiques the picked ones.
