Priority fixes for askdoctors.jp

Ordered by impact and by how common each practice is among peers.

1. Priority 1 · Harden

   TLS 1.3 negotiated

   Observed: The TLS connection negotiated TLSv1.2.

   Why it matters: TLS 1.3 removes legacy cipher suites and completes the handshake in fewer round trips, so it is both safer and faster for new connections.

   What to do: Enable TLS 1.3 on your CDN or server. Keep TLS 1.2 available for older clients unless you have checked your audience.

   89% of Fitness & Health peers do this. Limit: Certificate and protocol were observed from one vantage point; CDNs can present different certificates by region.
