Poem

🐰 Hops and snippets, versions anew,
Traefik updated, steady and true,
TinyAuth dons its v4 shoes,
Env names swapped for clearer cues,
A carrot cheer for simple moves 🥕

In @docker-compose.example.yml:
- Line 4: The docker-compose example uses a floating Traefik tag ("image:
traefik:v3"), which makes builds non-reproducible; update the image tag to a
specific pinned version (e.g., "traefik:v3.6.6") in this file and also update
the corresponding reference in docker-compose.dev.yml (which currently uses
"traefik:v3.3") so both files consistently pin to the same stable v3.x release.
- Line 21: The docker-compose service using image
ghcr.io/steveiliop56/tinyauth:v4 uses v3 env names and is missing a required
secret: rename TINYAUTH_APPURL to APP_URL and TINYAUTH_AUTH_USERS to USERS
(ensure the value is in the v4 user:hashed_password format), and add either
SECRET (32-char random string) or SECRET_FILE to the tinyauth environment block
for session signing; keep the existing volume mount for persistence and leave
the Traefik middleware address (/api/auth/traefik) unchanged.
