<b>Trending audio drives a median 22% of Reels reach — but only in a 5-day window</b>
The audio page is a real discovery surface with a sharp expiry.

— Audio age 0-2 days (rising): ██████ 28% of reach via audio page
— 3-5 days (peak): ████ 19%
— 6-10 days (saturated): █ 6%
— 10+ days: ▏ 2%

By the time an audio is obviously trending, the window is closing. The edge is using sounds at 500-5,000 uses, not 500k. Track the use-count growth rate, not the absolute count — acceleration is the signal.
