Mastodon on the current mastodon/mastodon:latest (Ruby 4.0 / Rails 8.1.3) aborts at Zeitwerk eager_load_all (task: non-zero exit 1) without a usable VAPID key. The two keys were declared 'plain', so under CI allow-empty-plain they render empty and the web+sidekiq services never converge. Omitting the env vars (0fc5408db) was not enough: empty and absent both crash identically, so a valid key must be present. Add 'vapid_private'/'vapid_public' credential algorithms that emit one linked P-256 keypair (private = unpadded base64url 32-byte scalar, public = unpadded base64url uncompressed point 0x04||X||Y), wire the mastodon schema to them, and render both keys unconditionally.
