# services/flowtrack.nix — Kayla's private period tracker.
#
# The application and NixOS module live in the standalone flowtrack flake.
# nginx is the only public listener and Authelia admits just kayla and fred;
# the app maps them to owner and read-only viewer. Nightly snapshots go
# straight to the SSD branch of the pool (not via mergerfs), which had the
# cleanest SMART record of the data disks.
