The README previously described this stack as shared by "every project
under Documentos/", which is just this machine's local checkout location,
not something the repo itself should assume. Every project lives in its
own git repository; the path to this repo's checkout is a per-project
setting (ZITADEL_ADMIN_PAT_DIR), not a fixed convention.
Also drops leftover em dashes across the docs and compose comments for
plainer prose.
Postgres, Zitadel and SeaweedFS were previously duplicated or fragilely
cross-referenced across the Musify, Ping and docker-manager repos. This
consolidates them into one place: compose.yml is the production shape
(no published ports, joins infra-net), compose.dev.yml is a thin overlay
that publishes ports for local development.
