          # Switch apt to HTTPS mirrors. Measured from this runner on
          # 2026-08-04: the SAME index file takes 20.1s over http:// and 3.1s
          # over https://. apt fetches many indexes serially, so http:// does
          # not read as "slow" -- it reads as a hang (zero bytes in
          # /var/cache/apt/archives after 3+ minutes, apt's http workers parked
          # in S state). rocker/r-ver:4.4 already ships ca-certificates and
          # apt 2.8.3 has the https method built in, so nothing needs to be
          # installed over http first to bootstrap this.
