All the old photos show that one, but we sold out and switched.)\n\nLabel: small kraft-paper label on the front, black text, \"CEDAR & SMOKE\" with a tiny pine tree drawing.\n\nThe wax is creamy off-white.

Gets tons of likes.\n- The big home-goods chain's listings, where every product sits alone, sharply lit, soft shadow underneath.\n\nOther:\n- My sister thinks it should be lit with a flame in every photo.\n- Listing goes live Nov 15 for the holiday rush.","rules":[{"type":"maxWords","max":130},{"type":"plainText"}],"mistakes":[{"title":"Not checking which jar is current","why":"The AI may describe the old amber jar with the cork lid, which the notes say is gone.","fix":"Add: \"Show the current jar: frosted white glass, matte black lid.\"","checks":["r0"]},{"title":"Leaving out the marketplace rules","why":"The AI goes for the moody shot with pinecones and a walnut table, which the marketplace will reject.","fix":"Add: \"Pure white #FFFFFF background, square 1:1, no props.\"","checks":["r1"]},{"title":"No negative prompt","why":"Image tools add props and random text unless you tell them what to leave out.","fix":"Add a last line: \"Negative prompt: props, table, pinecones, extra text, logos.\"","checks":["r2"]},{"title":"Getting options and tips","why":"The AI writes headings, three variations and photography advice.","fix":"Add: \"Output only the prompt and the Negative prompt line, plain text.\"","checks":["plainText","maxWords"]},{"title":"Trusting the AI to count words","why":"Product descriptions pile up unless you cap them.","fix":"Add: \"Prompt paragraph about 50 words.\"","checks":["maxWords"]}],"promptHints":[{"label":"Says the background","patterns":["#?FFFFFF","pure white","white background"]},{"label":"Sets the shape","patterns":["1\\s*:\\s*1","square"]},{"label":"Rules out props","patterns":["no props","no (pinecones|table|objects)"]},{"label":"Adds a negative prompt","patterns":["negative prompt"]},{"label":"Names the current jar","patterns":["frosted","black lid","current"]}],"hint":"Your notes mix old photos, moody ideas and the marketplace's strict rules.
