Media Generation (Fal.ai) — v3.1

Leading words: pick the model, run the script, dual-model ads, one image per message, native filesystem path.

Decision model (read this first):

1. Pick the job: still / edit / upscale / video / Instagram ad pair.
2. Run scripts/generate.py (or the documented fal_client call). Do not paste a rotated key; use FAL_KEY="$FAL_KEY".
3. Image-to-image when a reference exists. Dual-model for ad concepts (Nano Banana Pro Edit + Ideogram v4).
4. One image per chat message (Telegram).
5. Depth: references/endpoint-models.md, references/model-input-formats.md, references/high-conversion-prompting.md, references/fal-key-troubleshooting.md, references/wix-product-image-extraction.md.
