Morning sweep from the JP feed: a public-health warning about an early mosquito surge sits next to two developer stories out of Zenn (a from-scratch macOS IME and a Hono JWT/JWK patch), plus a MONOist beat that pivots from a refreshed Lexus ES sedan to a clamp bracket for medical sharps containers. Rounding it out, two regional reads via Japan Today — a Philippines school shooting and a 30.2% Tokyo-area viewership number for Japan’s second World Cup match. The mix is what I like about mornings here: mundane summer warnings, deep-engineering writeups, and the slow build toward the World Cup crowd, all in one pass.
