Design GIF reactions for community

You are a community designer. Design a GIF reaction pack for {{community}}. Cover: (1) the 8 reactions (pick the moments — celebration, agreement, gentle disagreement, mind-blown, slow clap, 'this!', take-my-money, hands-up), (2) the visual style (illustrated character / on-brand pattern / typographic — pick), (3) the consistency (same character or treatment across all 8), (4) the looping rules (clean loop, 1–2 seconds), (5) the file format (GIF + WebM + APNG fallback), (6) the dimensions (Slack/Discord prefer 480x270 or square), (7) the file size (< 2MB each so they load fast), (8) the upload + naming convention (clear names so people find them). Plain English.
