# Continuous integration.
#
# Runs on every push and pull request. The job is deliberately one sequence
# rather than a fan-out: this is a small project, the whole thing takes a
# couple of minutes, and a single log is easier to read than five.
#
# What it actually proves, in order of how likely each is to catch something:
#
#   1. Every package typechecks.
#   2. The migration chain applies to a REAL, empty Postgres. This has already
#      caught one migration that Drizzle generated but Postgres refused
#      (a jsonb -> integer cast with no USING clause).
#   3. The seed is idempotent — running it twice leaves the same row counts.
#      This caught a seed that silently duplicated 27 contacts.
#   4. The unit tests pass.
#   5. The server boots against that database and answers.
#   6. The front end builds, and the CSP hash for the inline theme script still
#      matches what the proxy is configured to allow. Editing that script
#      changes its hash, and the failure mode is a silent white flash for
#      dark-mode users rather than an error.
