The demo container used to invent a "Hello, world" page in code via
docker/seed-demo.php. That diverged from the real Scriptor home site
(https://scriptor-cms.dev / live mirror scriptor.cms) which has the
canonical Scriptor demo content — themed pages, Articles with sample
posts, Contact + Footer Pages hierarchy, real Unsplash imagery.

This makes the Docker demo show the SAME site as production:

  docker/seed-demo.sql            — sqlite3 dump captured via
                                    `vendor/bin/imanager dump`
                                    (full schema + data, 93 lines)
  docker/seed-demo-uploads.tar.gz — public/uploads/ for the three
                                    referenced image dirs (568 KB,
                                    ustar format to keep alpine
                                    busybox tar quiet)

The entrypoint now restores the snapshot on first start (no DB),
then runs schema:migrate so a dump captured on an older schema is
caught up if the image carries newer migrations. The programmatic
seed-demo.php is gone.

Admin credentials in the seed match scriptor.cms: admin /
gT5nLazzyBob — bcrypt-hashed.

Refreshing the seed when scriptor.cms content evolves:
  vendor/bin/imanager dump --db=data/imanager.db > docker/seed-demo.sql
  COPYFILE_DISABLE=1 tar --format=ustar -czf docker/seed-demo-uploads.tar.gz \
    -C public uploads/<referenced-subdirs>

Verified locally on macOS Docker 28.1:
  - up -d --build → seed restored, no tar warnings, all 8 pages
    routable (incl. nested /some-pages/legal-notice/), uploaded
    images served from /uploads/.
  - down (no -v) + up → entrypoint sees DB, skips seed, state preserved.
