Return:
1) ONE-LINER (under 14 words) — for category cards
2) SHORT (≈30 words, 2–3 sentences) — for the buy box
3) LONG (≈80 words, 4–6 sentences) — for the product page hero

Lead each version with the buyer's job-to-be-done, not the feature list. Use AU English. No "unleash", no "revolutionary", no "game-changing".
