Using fizzy.localhost causes CORS errors when using minio for Active
Storage because the minio endpoint is at minio.fizzy.localhost — a
sibling subdomain, not a subdomain of the app host. Switching to
app.fizzy.localhost makes both hosts subdomains of fizzy.localhost,
resolving the CORS issue. See #2814 for the related minio CORS fix.
fizzy.localhost will continue to work if people want to use it, but all
docs and scripts have been updated to point to app.fizzy.localhost.
* Split docs/API.md into per-resource sections under docs/api/
* Move API endpoints index above authentication in docs/api/README.md
* Fix trailing comma in boards.md JSON example
* Fix trailing comma in cards.md, add Response label to identity.md, add Rich Text to endpoint index
