Title or description value invalid

CAT_VALIDATION_ERROR_TITLE_INVALID and CAT_VALIDATION_ERROR_DESCRIPTION_INVALID fire when text content includes disallowed characters, all caps, excessive punctuation, or HTML markup. Strip HTML and promotional symbols before submitting the feed.

Snap Catalog Manager validates titles against character limits, casing rules, and content policies — promotional language, all-caps, special characters, or keyword-stuffed titles are rejected.

1. Trim title to the channel's character limit (most: 150–200 chars).
2. Use Title Case — capitalize first letters of major words, not entire words. Remove ALL CAPS phrases.
3. Remove promotional language: 'SALE', 'Best Quality', 'Free Shipping', 'Buy Now', etc.
4. Format consistently: Brand + Model + Key Specs + Color/Size + Pack.
5. Re-submit; title updates typically propagate within 1–4 hours.

• Smart quotes from Word/Docs — Unicode chars often fail title validation
• Repeating brand name multiple times — flagged as keyword stuffing
