ChatGPT image-gen prompts for NuroPicks role + emoji icons

Paste each prompt as-is into ChatGPT (with image gen) or Sora / DALL-E. Always download as PNG, 1024×1024 source. Discord auto-downscales to 64–256. Save final files to scripts/brand/role-icons/<slug>.png (or vocab-emojis/) then rerun scripts/apply-sport-role-icons.cjs to push to the guild.

Universal style guardrails (paste once at the top of any chat)

I need a set of Discord role icons. Strict rules for every image:

1024×1024 PNG, fully transparent background.

SINGLE solid color sport icon (no gradients, no two-tone shading, no outline strokes in a different color). Flat, modern, vector look.

Centered subject filling about 75% of the canvas, with breathing room on all four sides so the icon stays clean when downscaled to 64×64 inside a Discord role pill.

No text, no logos, no league marks (trademark risk). Just the sport's iconic object.

Clean silhouette readable as a thumbnail.

Keep it sport-recognizable to a casual fan, not abstract art.

Reply "got it" before sending the per-sport prompts.

Vocab emoji icons (15)

For these the constraint is even tighter because Discord renders emojis at ~32×32 in chat. Symbols must be VERY simple silhouettes.

Drop-in workflow

Generate each PNG, name it exactly per the slugs above.
Drop into scripts/brand/role-icons/<slug>.png for sports OR scripts/brand/vocab-emojis/np_<term>.png for vocab.
Run railway run --service nurobets-bot node scripts/apply-sport-role-icons.cjs for sport roles (replaces in place — old icons get evicted).
For new emojis (none yet uploaded for the vocab set, the text-monogram fallback is live), delete the existing emoji in Discord then rerun node scripts/upload-vocab-emojis.cjs.

The text-monogram fallbacks I generated tonight stay as a safety backup. Replace them whenever ChatGPT outputs land.
