Sorry, something went wrong.
The Dockerfile copies only package*.json before running `npm ci`, but the postinstall hook executes `node scripts/download-pocketbase.js`. Since scripts/ has not been copied yet, npm ci fails with MODULE_NOT_FOUND and the build aborts. Copy scripts/ before npm ci so postinstall succeeds. The rest of the source is still copied afterward to preserve layer caching for the dependency install step.
start.sh has a #!/bin/bash shebang and uses bash-specific syntax
({1..30} brace expansion and `wait -n`), plus calls curl to wait
for PocketBase health. The node:20-alpine base image ships neither
bash nor curl, so the container fails immediately at runtime with
"./start.sh: not found" (ENOENT on the shebang interpreter).
Install bash and curl via apk so start.sh runs as authored.

Summary
Two independent bugs in deploy/docker/Dockerfile block every Docker deploy from this file (and any PaaS that builds from it — Coolify, Railway-via-Dockerfile, etc). Both fixes together are needed to get a usable image.
Bug 1 — npm ci fails because postinstall can't find its script
The Dockerfile copies only package*.json before running npm ci, but the postinstall hook executes node scripts/download-pocketbase.js. At that point scripts/ is not in the image, so npm aborts:
```
Missing Svelte config file in /app — skipping
Error: Cannot find module '/app/scripts/download-pocketbase.js'
```
Fix: copy scripts/ before npm ci.
Bug 2 — container crash-loops with ./start.sh: not found
deploy/railway/start.sh has a #!/bin/bash shebang and uses bash-specific syntax ({1..30} brace expansion, wait -n), plus calls curl to wait for PocketBase to become healthy. node:20-alpine ships neither bash nor curl, so the container fails immediately at runtime:
```
/usr/local/bin/docker-entrypoint.sh: exec: line 11: ./start.sh: not found
```
This message is misleading — the file exists and is executable. The error is ENOENT on the shebang interpreter (/bin/bash).
Switching the shebang to #!/bin/sh is not viable because BusyBox sh doesn't support the bash features the script uses.
Fix: install bash and curl via apk.

Verified
Built and ran the image locally on linux/arm64. Container starts cleanly:
```
Starting tinykit...
Starting Pocketbase...
Pocketbase is ready!
Superuser ready!
Starting SvelteKit server...
Listening on http://0.0.0.0:3000
```
GET /tinykit → HTTP 200.
